Mushroom cultivation is an economical biotechnological process for the conversion of various unused lignocellulosic wastes into protein rich food. The present study was conducted to assess the suitability of three different cereal grains viz., bajra (Pennisetum glaucum L.), wheat (Triticum aestivum L.)  and maize (Zea mays L.) for spawn production of Macrocybe gigantea  (Massee) Pegler & Lod. and further its cultivation on two agrowastes (wheat straw and paddy straw) for assessing biological efficacy. It was observed that among the three cereal grains tested, bajra grains took significantly (P?0.05) less time for spawn development. Moreover, a minimum period of spawn run (16.3 days), highest sporophore yield (343.6g/500g of dry substrate) and biological efficiency (68.7%) were also recorded from substrate bags inoculated with bajra grain spawn. These results suggest the use of bajra grain spawn for quick and successful cultivation of M. gigantea.

Mushrooms are type of white-rot fungi such as basidiomycetes, which degrades a lot of agro wastes by the secretion of precious bioconversion enzymes and produce the final enriched product. These enzymes take part in organic and inorganic waste remediation in the environment. This review analysed from the standpoint of scientists reserching in lignolytic enzyme production from various mushroom cultivation and also highlights the role of recent approaches within the production of giant volume of commercially important enzymes from biodegradable wastes. Then the proceeding work is to survey the novel lignolytic enzyme production aspects and their major characteristics, microbial sources such as basidiomycetes (white-rot fungi), downstream processing, relevant biochemical properties, diverse applications, enzyme mycotechnology and some recent research developments.
