Abstract
Basidiomycetes fungi usually grow from hyphae that become interwoven into mycelium and can be propagated on a base of steam sterilised cereal grains such as wheat sorghum rye millet maize and barley. This mycelium-impregnated cereal is termed as spawn and typically used to propagate basidiomycetes fungi in mushroom cultivation. A study was designed to assess the potential of selected spawn grains as basidiomycetes growth substrates for enhancement of enzyme production. Barley sorghum and wheat as spawn grains were assessed for growth and multiplication of four white-rot biodegraders namely ST2 FBR FBW and FBJ G3. The preliminary findings indicated that mycelium grain weight was significantly highest in the wheat followed by sorghum grain after 14 days of incubation period whereas barley was observed not suitable for the growth of the respective biodegraders. FBW isolate had colonised sorghum rapidly within six days as compared to wheat grain seven days however the mycelia extension in wheat grain 4.96 cm was greater than recorded in sorghum grain 4.83 cm respectively at day-7 of incubation period. Additionally mycelial grain weight in sorghum was significantly lower 4.19 g than those recorded in wheat grain 5.55 g after 14 days of incubation period. The present results concluded that wheat is an ideal grain as growth substrate for rapid mycelium extension and multiplication of white-rot biodegraders and will be used in the formulation study.
