Abstract
ABSTRACT
The present investigations entitled “Studies on cultural requirements and cultivation technology
of some medicinal mushrooms” was undertaken to understand the cultural requirements, spawn
production technique of some medicinal mushrooms viz., Auricularia polytricha, Pleurotus ostreatus,
Pleurotus eryngii, Flammulina velutipes, Lentinula edodes and Ganoderma lucidum and above all their
cultivation technique so as to commercialize the cultivation of later five mushrooms. Different solid
media were tried for maintaining the pure cultures and PDA and MEA were found to support maximum
radial growth. In case of various liquid media, Glucose- asparagine solution was found to support
maximum mycelial growth of F. velutipes, L. edodes, P. eryngii and G. lucidum while Elliott’s and
Richard’s solution supported good growth in case of A. polytricha and P. ostreatus, respectively. An
optimum temperature of 250C and pH in acidic (4.5) to slightly acidic (6.5) range were found to be
preferred by these fungi. Glucose (a monosaccharide), sucrose (a disaccharide) and starch (a
polysaccharide) were recorded as good carbon sources. In case of nitrogen sources, ammonical nitrogen
and among amino acids, leucine, alanine and aspartic acid supported good growth. Trace elements viz.,
molybdenum, iron and manganese, vitamins viz., thiamine and biotin, and growth regulators viz.,
gibberellic acid supported best mycelial growth of the test fungi. For spawn production, grain spawn was
evaluated as good substrate. While for cultivation, good yield was recorded using supplemented (5 per
cent and wood chips) sawdust in all the test fungi while wheat straw was recorded to give good yield in
case of P. ostreatus and P. eryngii that could be recommended for commercial cultivation as they showed
superior yield than other substrates
