Abstract

Discarded oyster mushroom beds were examined for their bioactive compounds and industrially important enzymes. Spent oyster mushroom beds were used as substrate by micro organisms such as Bacillus megaterium, Pseudomonas aeruginosa, Proteus vulgaris, Bacillus amyloliquefaciens and Micrococcus sp were used production of industrially important enzymes and bioactive compounds. Bioactive compounds such as total sugars and reducing sugars were produced by B. amyloliquefaciens. B. megaterium, B. amyloliquefaciens showed positive result in lipid hydrolysis. Microorganisms such as B. megaterium, P. aeruginosa, P. vulgaris, B. amyloliquefaciens, and Micrococcus sp used spent oyster mushroom bed as good source for production of industrially important enzymes such as laccase, lignin peroxidase , manganese peroxidase, cellulase, protease, amylase, pectinase, xylanase and catalase.

Keywords: Spent oyster mushroom beds, B. amyloliquefaciens, laccase, cellulase, amylase, xylanase.
