Optimization of the cultivation conditions for mushroom production with European wild strains of Agaricus subrufescens and Brazilian cultivars

Abstract

BACKGROUND

The almond mushroom Agaricus subrufescens (formerly Agaricus blazei or Agaricus brasiliensis) is cultivated at commercial level in Brazil and some Asian countries on local substrates and casing mixtures. Despite its tropical origin, A. subrufescens might be a seasonal option for mushroom growers in western countries, where some wild strains have been isolated. For this purpose, cultivation conditions were developed starting from the substrate and casing mixture commonly used for commercial production of the button mushroom Agaricus bisporus in France.

RESULTS

The commercial compost, based on wheat straw and horse manure, used for A. bisporus and the casing mixture (peat and limestone) supplemented with fine sand proved efficient to grow A. subrufescens. Increasing the depth of the casing layer improved significantly the yield and time to fruiting. Daily variations in temperature did not markedly modify the yield. Significantly higher mushroom biomass was obtained with three wild European strains compared with three Brazilian cultivars. The very productive wild strain CA438-A gave mushrooms of size and dry matter content comparable to those of a cultivar.

CONCLUSION

Commercial production of A. subrufescens can be developed in western countries on the wheat straw-based substrate commonly used for A. bisporus in these regions, by a simple modification of the casing mixture and maintaining the incubation temperature throughout the crop, which is expected to save energy during summer. Good yields were obtained cultivating European strains under optimised parameters. © 2013 Society of Chemical Industry

Antioxidant activity and β-glucan contents of hydrothermal extracts from maitake (Grifola frondosa)

Abstract

Maitake (Grifola frondosa) was hydrothermally extracted at 4 different temperatures (121, 130, 140, and 150°C) for 30 and 60 min, and the total phenolic content (TPC), antioxidant activity, and β-glucan content of the extracts was evaluated. The highest TPC was detected in the extract at 150°C treated for 60 min with 13.61 mg gallic acid equivalents (GAE)/g. The antioxidant activity of the maitake extracts, evaluated by determining DPPH radical scavenging activity (RSA), ABTS RSA, reducing power, and tyrosinase inhibitory activity increased with increasing treatment temperature and time. The content of β-glucan was the highest (5.13%) in the extract prepared at 140°C for 30min. These results suggest that hydrothermal extraction could be used as a tool to increase the antioxidant activity of maitake extracts.

Drying effects on the antioxidant properties of polysaccharides obtained from Agaricus blazei Murrill

Abstract

Three polysaccharides (ABMP-F, ABMP-V, ABMP-A) were obtained from Agaricus blazei Murrill via methods such as freeze drying, vacuum drying and air drying, respectively. Their chemical compositions were examined, and antioxidant activities were investigated on the basis of assay for hydroxyl radical, DPPH radical, ABTS free radical scavenging ability and assay for Fe2+_chelating ability. Results showed that the three ABMPs have different physicochemical and antioxidant properties. Compared with air drying and vacuum drying methods, freeze drying method resulted to ABMP with higher neutral sugar, polysaccharide yield, uronic acid content, and stronger antioxidant abilities of hydroxyl radical, DPPH radical, ABTS radical scavenging and Fe2+-chelating. As a result, Agaricus blazei Murrill polysaccharides are natural antioxidant and freeze drying method serves as a good choice for the preparation of such polysaccharides and should be used to produce antioxidants for food industry.

مقاله 2013: بررسی خصوصیات ژن aap1 قارچ دکمه ای آگاریکوس بایسپوروس Agaricus bisporus که در محصول آن در تحمل دمای بالا و همچنین استرس نقش دارد

Characterization of the aap1 gene of Agaricus bisporus, a homolog of the yeast YAP1

Abstract

The structure, homologies, polymorphism and expression profiles of a new gene, aap1, have been studied for precisely characterizing it and defining its putative involvement in thermo-tolerance of both vegetative mycelium growth and sporophore differentiation. Sequence polymorphism was analyzed in 3 homokaryons of A. bisporus and 24 strains having different abilities for mycelial growth at temperatures above 30 °C and for producing mature fruiting bodies at 25 °C. The level of gene expression was measured by real-time PCR both in vegetative mycelium after transfer from 25 to 32 °C and in primordia and fruiting bodies produced during cultures at 17 or 25 °C. The results indicated that aap1 gene belong to a new subfamily of the yeast YAP1 homologs. It is not a dominant contributor to the thermo-tolerance of A. bisporus, but the protein it encodes may be involved as an overall stress resistance transcription factor. The way Aap1 senses redox level differs from that of AP-1-like transcription factor Yap1.

Possibility to use the spent mushroom substrate in soil fertilization as one of its disposal methods.


Abstract

Production of mushroom is a branch of agriculture intensively growing in the world and Poland. This production introduces into natural environment a large spent mushroom substrate waste that requires utilization. Agricultural and non-agricultural disposal of the spent mushroom substrate, is possible when it is secured in a suitable manner, minimizes the risk of transmission of pests, fungi, bacteria, vinises, and weed seeds. After application into the soil SMS improves its physical properties and increases the content of macro- and microelements.

Combined Vacuum Impregnation and Electron-Beam Irradiation Treatment to Extend the Storage Life of Sliced White Button Mushrooms (Agaricus bisporus)

Abstract

This study assessed the application of an antibrowning solution using vacuum impregnation (VI) and then electron-beam irradiation as a means to extend the shelf life of sliced white button mushrooms (Agaricus bisporus). A preliminary study helped to determine the best antibrowning solution and VI process parameters. Mushroom slices were impregnated with 2 g/100 g ascorbic acid + 1 g/100 g calcium lactate; 2 g/100 g citric acid + 1 g/100 g calcium lactate; 1 g/100 g chitosan + 1 g/100 g calcium lactate; and 1 g/100 g calcium lactate at different vacuum pressures and times and atmospheric restoration times. Selection of the antibrowning solution and VI parameters was based on texture and color of the mushroom slices. Next, the slices were irradiated at 1 kGy using a 1.35-MeV e-beam accelerator. Physicochemical, sensory, and microbial quality of mushrooms was monitored for 15 d at 4 °C. The best impregnation process in this study was 2 g/100 g ascorbic acid and 1 g/100 g calcium lactate at 50 mm Hg for 5 min and an atmospheric restoration time of 5 min. The control (untreated) samples suffered structural losses throughout storage. Only the vacuum impregnated-irradiated samples had acceptable color by the end of storage. Sensory panelists consistently preferred the samples produced with VI and irradiation because exposure to ionizing radiation inhibited growth of spoilage microorganisms.

Practical Application

Extending the shelf life of mushrooms is important for their marketing and distribution and reliable preservation methods are still needed. Treating sliced mushrooms with vacuum impregnation and electron-beam irradiation introduces physiologically active components such as beneficial antioxidants, vitamins, and cations, while assuring safety and maintaining quality.

Mushroom immunomodulators: unique molecules with unlimited applications

Highlights

Mushroom immunomodulators as safe alternatives to chemical drugs in medicine.
Application of mushroom immunomodulators in animal feed and aquaculture.
Mushroom cultivation for industrial production of immunomodulators.

For centuries, mushrooms have been used as food and medicine in different cultures. More recently, many bioactive compounds have been isolated from different types of mushrooms. Among these, immunomodulators have gained much interest based on the increasing growth of the immunotherapy sector. Mushroom immunomodulators are classified under four categories based on their chemical nature as: lectins, terpenoids, proteins, and polysaccharides. These compounds are produced naturally in mushrooms cultivated in greenhouses. For effective industrial production, cultivation is carried out in submerged culture to increase the bioactive compound yield, decrease the production time, and reduce the cost of downstream processing. This review provides a comprehensive overview on mushroom immunomodulators in terms of chemistry, industrial production, and applications in medical and nonmedical sectors.

The cultivation of Agaricus bisporus on the spent substrate of Flammulina velutipes



A large amount of spent substrate produced from the commercial culturing of edible mushrooms is becoming an environmental pollution issue. Here spent Flammulina velutipes substrate, supplemented with unfermented cow dung, gypsum, and calcium superphosphate, as the main compost constituent for the cultivation of Agaricus bisporus were tested. Compared to the conventional culturing method using rice straw as the primary compost constituent, the reuse of spent F. velutipes substrate reduces the cost, shortens the production cycle, and increases the economic yield of the A. bisporus culture. Therefore, such recycling is not only practical, but less environmentally damaging as well.

 

Key words: Spent mushroom substrate, Flammulina velutipes, compost, Agaricus bisporus.

 An improved rapid composting procedure enhance the substrate quality and yield of Agaricus bisporus

 The effect of passive aeration on substrate quality, composting period and yield was studied using different perforated high-density polyethylene (HDPE) pipes arrangements, as a composting method for substrate preparation to Agaricus bisporus cultivation. The ingredients are, mixture of wheat straw (60%), wheat bran (5.5%), chicken manure (31%), urea (0.5%) and gypsum (3%) with initial moisture (75%) used for composting. It was demonstrated that passive aeration is the key parameter controlling composting process, shortened the compost period, enhance the substrate quality and Agaricus yield as of pile composting. The substrate physico-chemical characteristics that is, moisture content, temperature pattern, bulk density, pH, electric conductivity, C: N ratio and thermophilic fungi activity varied significantly with composting period. The parallel arrangement (10% perforations) was found best among all the passive aeration treatments for achieving the quality substrate in shortest composting period of 16 day and enhance the A. bisporus yield up to 27.6%. This study also opens possibility to cultivate A. bisporus on a lingo-cellulosic, non-pasteurized, non-conditioned, aerated substrate and that composting for 16 days improve the mushroom yield with minimum energy, labor and infrastructure.

Effects of Compost on Mycelia Growth and Fructification, Mineral Elements and Proximate Composition of Pleurotus pulmonarius (Fries)

O Ugioro, M Kadiri, YO Fademu

Abstract

Studies were conducted on the growth and cultivation of Pleurotus pulmonarius (Fries) singer on lingocellulosic waste. Long composted substrate formulations of sawdust (86%) + rice bran (10%) + cassava peel (4%) supported the longest mycelia growth and density. Long composted also produced larger fruitbodies and significant increase in number of fruitbodies and compost % yield compared with uncomposted substrate having the same formulations. The mineral elements of Mg, Cu, Fe, Mn, Na, K, and P were found to increase from very young to mature fruitbody of both composted and uncomposted substrate with preponderance of potassium. Similar results were obtained for crude protein. However, organic carbon and organic matter tend to decrease from very young to mature fruitbody of composted and uncomposted substrates.

Complete Mitochondrial Genome of the Medicinal Mushroom Ganoderma lucidum

Abstract

Ganoderma lucidum is one of the well-known medicinal basidiomycetes worldwide. The mitochondrion, referred to as the second genome, is an organelle found in most eukaryotic cells and participates in critical cellular functions. Elucidating the structure and function of this genome is important to understand completely the genetic contents of G. lucidum. In this study, we assembled the mitochondrial genome of G. lucidum and analyzed the differential expressions of its encoded genes across three developmental stages. The mitochondrial genome is a typical circular DNA molecule of 60,630 bp with a GC content of 26.67%. Genome annotation identified genes that encode 15 conserved proteins, 27 tRNAs, small and large rRNAs, four homing endonucleases, and two hypothetical proteins. Except for genes encoding trnW and two hypothetical proteins, all genes were located on the positive strand. For the repeat structure analysis, eight forward, two inverted, and three tandem repeats were detected. A pair of fragments with a total length around 5.5 kb was found in both the nuclear and mitochondrial genomes, which suggests the possible transfer of DNA sequences between two genomes. RNA-Seq data for samples derived from three stages, namely, mycelia, primordia, and fruiting bodies, were mapped to the mitochondrial genome and qualified. The protein-coding genes were expressed higher in mycelia or primordial stages compared with those in the fruiting bodies. The rRNA abundances were significantly higher in all three stages. Two regions were transcribed but did not contain any identified protein or tRNA genes. Furthermore, three RNA-editing sites were detected. Genome synteny analysis showed that significant genome rearrangements occurred in the mitochondrial genomes. This study provides valuable information on the gene contents of the mitochondrial genome and their differential expressions at various developmental stages of G. lucidum. The results contribute to the understanding of the functions and evolution of fungal mitochondrial DNA.

Chemical, enzymatic and cellular antioxidant activity studies of Agaricus blazei Murrill

ABSTRACT

Mushrooms possess nutritional and medicinal properties that have long been used for human health preservation and that have been considered by researchers as possible sources of free radical scavengers. In this work, the antioxidant properties of water extracts from Agaricus blazei Murill, produced by maceration and decoction, are demonstrated in vitro. Resistance to oxidation is demonstrated through three mechanisms: i) inhibition of enzymatic oxidative process, with 100% inhibition of HRP (horseradish peroxidase) and MPO (myeloperoxidase); ii) inhibition of cellular oxidative stress, with 80% inhibition of the oxidative burst of polymorphonuclear neutrophils (PMNs); and iii) direct action over reactive species, with 62% and 87% suppression of HOCl and superoxide anion radical (O2• –), respectively. From the data, it was concluded that the aqueous extract of A. blazei has significant antioxidant activity, indicating its possible application for nutraceutical and medicinal purposes.

Keywords: Agaricus blazei Murrill; antioxidant; oxidant species; chemiluminescence; polymorphonuclear neutrophils

ABSTRACT

The fruiting bodies of the edible mushroom Lactarius salmonicolor (Russulaceae) collected from the wild were extracted with solvents of increasing polarity and evaluated for their antioxidant capacity by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method. Additionally, their total phenolic content was evaluated by a modification of the Folin-Ciocalteu method. The methanol extract showed the most potent radical scavenging activity (inhibition of 36.7% of DPPH at 3 mg/mL and 6.8 mg gallic acid equivalents/g of dry extract), and was further fractionated. Total phenolics and antioxidant activity found to be significant higher in the fractions of increased polarity. The phytochemical investigation which was performed by chromatographic and spectrometric techniques led to the isolation of nine compounds from the methanol extract and the identification of 10 fatty acids and fatty acids esters from the dichloromethane extract. Evaluation of the antioxidant activity of isolated compounds showed p-hydroxybenzoic acid (4) to be the most active. Among the various compounds found, the rare azulene type 7-acetyl-4-methylazulene-1-carboxylic acid (1) has been identified, which had been isolated only once before from L. deliciosus. Therefore, this compound seems to have some chemotaxonomic value for Lactrarius species exuding orange to red milk.

Effect of Mushroom Residue Used in Washed Soil on the Growth of Tomatoes

In order to reveal the regulating capacity of mushroom residue on washed soil, pots experiments were carried out. The growth of tomatoes planted on washed soil amended by mushroom residue were measured. Mushroom residue can be helpful to improve the plant height, stem diameter, the aerial parts fresh weight, root fresh weight, leaf photosynthetic rates and photosynthesis, and lay a good foundation for the growth of tomatoes. The effect of mushroom residue is the most significant. Among all the treatments of adding 2.5%, 5%, 10% mushroom residue, adding 10% mushroom residue is the best. It can significantly enhance the growth and photosynthesis of tomatoes, and is among the best of these three soil treatments for washed soil.

Main Phenolic Compounds of the Melanin Biosynthesis Pathway in Bruising-Tolerant and Bruising-Sensitive Button Mushroom (Agaricus bisporus) Strains

Abstract

Browning is one of the most common postharvest changes in button mushrooms, which often results in economic losses. Phenolic compounds, which are associated with browning, were extracted from the nonbruised and bruised skin tissue of various button mushrooms with a sulfite-containing solution and analyzed with UHPLC-PDA-MS. In total, 34 phenolic compounds were detected. Only small differences in the total phenolic content between bruising-tolerant and -sensitive strains were observed. The contents of γ-l-glutaminyl-4-hydroxybenzene (GHB) and γ-l-glutaminyl-3,4-dihydroxybenzene (GDHB) correlated with bruising sensitivity; for example, R2 values of 0.85 and 0.98 were found for nonbruised brown strains, respectively. In nonbruised skin tissue of the strains with brown caps, the GHB and GDHB contents in sensitive strains were on average 20 and 15 times higher, respectively, than in tolerant strains. GHB and GDHB likely participate in the formation of brown GHB–melanin, which seemed to be the predominant pathway in bruising-related discoloration of button mushrooms.

Potential of European wild strains of Agaricus subrufescens for productivity and quality on wheat straw based compost

Abstract

The Brazilian almond mushroom is currently cultivated for its medicinal properties but cultivars are suspected all to have a common origin. The objective of this work was to assess the potential of wild isolates of Agaricus subrufescens Peck (Agaricus blazei, Agaricus brasiliensis) as a source of new traits to improve the mushroom yield and quality for developing new cultures under European growing conditions. The wild European strains analysed showed a good ability to be commercially cultivated on wheat straw and horse manure based compost: shorter time to fruiting, higher yield, similar antioxidant activities when compared to cultivars. They have a valuable potential of genetic and phenotypic diversity and proved to be interfertile with the original culture of the Brazilian almond mushroom. Intercontinental hybrids could be obtained and combine properties from both Brazilian and European germplasm for increasing the choice of strains cultivated by the mushroom growers.
