Pleurotus sajor-caju Protein: A Potential Biosorptive Agent

Biosorption is a process in which microorganisms are used to extract and recover heavy metals from aqueous solutions. Mushrooms or macro fungi can act as effective biosorbents of toxic heavy metals. This process of biosorption is a result of physico-­chemical interactions between metal ions and cellular compounds. This study aims to investigate if a specific protein is over expressed during in situ biosorption by the fleshy macro fungi Pleurotus sajor-caju, when grown on the substrate jowar straw. The protein content was observed to increase with increase in the concentration of the heavy metal Zn (in the form of Zn (II) SO4) sprayed on a mushroom bed. Native PAGE demonstrated that from the total protein present, a specific protein, which requires further characterization, was over expressed. In addition, the total carbohydrate concentration was observed to decrease with increase in the protein content.

مقاله ۲۰۱۲: تاثیر طول های مختلف پایه، پیش سرما،‌ و ایجاد منفذ در بسته بندی ها روی ماندگاری و کیفیت قارچ دکمه ای در دماهای مختلف

سلام و خسته نباشید من میخواستم در مورد هر تن کمپوست قارچ چقدر محصول برداشت میشه مرسی و همچنین  اگر این کمپوست را در خواست بدهم مثلا از اذربایجان شرقی شهر میانه یا ترکمنچای به چه هزینه ای به دست ما میرسد  دوست دارم در همین زمینه اشتغا رایی کنم

بر اساس درصد بیان میشه- از ۱۵ درصد تا ۳۰ درصد بسته به نوع و شرایط کمپوست. یعنی به ازای هر تن کمپوست ۱۵۰ تا ۳۰۰ کیلو قارچ- کرایه ها متغیره از باربری ها بپرسید حدودا از ۴۰۰ شروع میشه برای حداقل خاور و ...

Potential uses of spent mushroom substrate and its associated lignocellulosic enzymes

Mushroom industries generate a virtually in-exhaustible supply of a co-product called spent mushroom substrate (SMS). This is the unutilised substrate and the mushroom mycelium left after harvesting of mushrooms. As the mushroom industry is steadily growing, the volume of SMS generated annually is increasing. In recent years, the mushroom industry has faced challenges in storing and disposing the SMS. The obvious solution is to explore new applications of SMS. There has been considerable discussion recently about the potentials of using SMS for production of value-added products. One of them is production of lignocellulosic enzymes such as laccase, xylanase, lignin peroxidase, cellulase and hemicellulase. This paper reviews scientific research and practical applications of SMS as a readily available and cheap source of enzymes for bioremediation, animal feed and energy feedstock.
