“…Faster degradation of fungicides in microflora inoculated treatments is attributed to the involvement of lignin degrading enzymes system. Some other findings have also revealed the role of laccase, Mn-dependant peroxidase and high carbon content in SMS in breakdown of organopollutants [22][23][24]. The SMS from Pleurotus pulmonarius has also been tried earlier to treat a PCP contaminated water system and after 2 days of incubation, 89% removal of PCP has been reported with 5% SMS [24].…”

Experiments were conducted both under in vitro and in situ conditions to determine the biodegradation potential of button mushroom spent substrate (SMS) and its dominating microbes (fungi and bacteria) for carbendazim and mancozeb, the commonly used agricultural fungicides. During 6 days of incubation at 30 ± 2°C under broth culture conditions, highest degradation of carbendazim (17.45%) was recorded with B-1 bacterial isolate, while highest degradation of mancozeb (18.05%) was recorded with Trichoderma sp. In fungicide premixed sterilized SMS, highest degradation of carbendazim (100.00-66.50 lg g -1 ) was recorded with mixed

“…More than 30 million tons of mushrooms were produced in 2013, which resulted in an accumulation of a large amount of spent mushroom compost (SMC) production. Approximately 1 kg of mushrooms generates 5 kg of SMC (Lau et al 2003;Phan and Sabaratnam 2012). Therefore, the waste management of SMC is a major problem confronted by mushroom producers.…”

The activities of xylanase extracted from spent mushroom composts (SMCs) of Coprinus comatus, Auricularia auricular, Pleurotus ostreatus, Pleurotus citrinopileatus, Agrocybe cylindracea, Hericium erinaceus, Hypsizygus marmoreus, and Tremella fuciformis were investigated. The crude extract from T. fuciformis SMC showed high xylanase activity with a value of 255.2 U/mg. Furthermore, this xylanase was purified using a combination of ammonium sulfate precipitation, diethylaminoethylcellulose (DEAE-cellulose), and gel filtration column chromatography. The enzyme was purified 20.7-fold with a yield of 43.1% and activity of 5293.8 U/mg. The purified xylanase showed maximum activity at 50 °C and pH 6, retained 80% activity after 1 h incubation at 50 °C, and sustained stability over a wide range of pH values (2 to 10). Under the optimal conditions, the enzyme exhibited a Km value of 2.5 mg/mL towards birchwood xylan. The activity of xylanase was enhanced in the presence of Mg 2+ , Ca 2+ , Ba 2+ , NH4 + , and Tween 80, while some metal ions, particularly Fe 3+ , inhibited its activity. The saccharification of several biomass wastes using the crude xylanase enzyme was studied. The results showed the potential for saccharification of alkaline-pretreated wheat bran solution where 75% saccharification was achieved.

“…It was observed that the addition of SMC to the contaminated medium reduced the toxicity, added enzymes, microorganisms, and nutrients for the microorganisms involved in degradation of PAHs (Lau, et al, 2003). Organic wastes like banana skin, spent mushroom compost and brewery spent grain in earlier studies were found to enhance the biodegradation of used lubricating oil up to 90% loss of oil within the period of 3 months (Abioye, et al, 2009b(Abioye, et al, , 2010.…”
