Abstract
Pleurotus tuber-regium is a tuberous wild mushroom species, highly expensive, nutritious, very rich in proteins and known to possess medicinal values. The dwindling forests and the absence of commercial cultivation of this mushroom have resulted in scarcity of the sclerotia. The study was conducted to determine the optimum temperature, pH and light regime for the growth of P. tuber-regium and evaluate the use of water hyacinth (Eichhornia crassipes), plantain (Musa sapiens) leaves, millet (Eleusine coracana) stalk and composted 'wawa' (Triplochiton scleroxylon) sawdust as substrates for its cultivation. Pleurotus tuber-regium grew fastest at 35°C, pH 6 and in continuous darkness. Only plantain leaf substrate produced fruitbodies and sclerotia whilst 'wawa' sawdust produced only sclerotia in bags. Plantain leaves yielded fruitbodies with a Biological Efficiency (B.E) of 54.47% while the sclerotia gave a B.E of 62.05%. The B.E value of 99.65% was obtained from sclerotia of 'wawa' sawdust. The sclerotium had highest crude protein content followed by the pileus and stipe in decreasing order. Knowledge of the growth requirements and the potential substrates will facilitate large scale production and commercialization of the fungus.

مقاله 2014: فعالیت آنتی اکسیدانی پلی ساکارید های استخراج شده از قارچ شاه صدف
Antioxidant activity of polysaccharide extracted from Pleurotus eryngii using Response surface methodologyHighlights- •Three polysaccharide fractions were obtained from Pleurotus eryngii.
- •Polysaccharide extracted by ultrasonic technology using Response surface methodology (RSM) optimized conditions.
- •Antioxidant capacities were investigated by radical-scavenging assay.
AbstractUltrasonic technology was applied for polysaccharide extraction from the fruiting bodies of P. eryngii
and response surface methodology (RSM) was used to optimize the effects
of processing parameters on polysaccharide extraction yield. Three
independent variables were extraction time (A), ultrasonic power (B) and
the ratio of solvent to sample (C), respectively. Results showed that
the maximum yield of P. eryngii polysaccharide (PEPS) was
obtained at an optimum condition: extraction time 39 min, ultrasonic
power 517 w, the ratio of water to material 19 mL/g, and the PEPS
extracting yield reached 34.3% under the conditions. PEPS were
precipitated into three crude polysaccharides, PEPS30, PEPS60 and
PEPS80, by different concentration of ethanol respectively. The
antioxidant activities of these three polysaccharides were evaluated.
The results showed that PEPS80 had the best reducing power, DPPH radical
scavenging ability and oxygen radical scavenging ability, followed by
PEPS60 and PEPS30. Keywords- antioxidant activity;
- polysaccharide;
- Pleurotus eryngii;
- response surface methodology (RSM)

مقاله 2014: جلوگیری از قهوه ای شدن و حفظ کیفیت قارچ دکمه ای آگاریکوس بایسپوروس با استفاده از تیمارهای تدخینی Browning inhibition and quality preservation of button mushroom (Agaricus bisporus) by essential oils fumigation treatmentAbstractThe effect of essential oil fumigation treatment on browning and postharvest quality of button mushrooms (Agaricus bisporus)
was evaluated upon 16 days cold storage. Button mushrooms were
fumigated with essential oils, including clove, cinnamaldehyde, and
thyme. Changes in the browning index (BI), weight loss, firmness,
percentage of open caps, total phenolics, ascorbic acid, microbial
activity and activities of polyphenol oxidase (PPO), phenylalanine
ammonia lyase (PAL), and peroxidase (POD) were measured. The results
indicated that all essential oils could inhibit the senescence of
mushrooms, and the most effective compound was cinnamaldehyde.
Fumigation treatment with 5 μl l−1 cinnamaldehyde decreased
BI, delayed cap opening, reduced microorganism counts, promoted the
accumulation of phenolics and ascorbic acid. In addition, 5 μl l−1
cinnamaldehyde fumigation treatment inhibited the activities of PPO and
POD, and increased PAL activity during the storage period. Thus,
postharvest essential oil fumigation treatment has positive effects on
improving the quality of button mushrooms. http://www.sciencedirect.com/science/article/pii/S0308814613015185
