Title: Standardization of parameters for cost effective quality mushroom spawn production
Author: Ajay Singh, Sujata & Jitendra Kumar
For mushroom spawn production polypropylene bags (PP) of various sizes & gauges without respiratory filters are being used in India. Out of three sizes and gauges used, PP bags of 16”(L) X 7”(B) size of 110 gauge found best in terms of effective autoclaving & shaking during incubation. Plugging of spawn substrate bags with polyfill (polymer) in place of non absorbent cotton reduced the cost of spawn production by three percent. Immediate washing of boiled Triticum aestivum (wheat) grains with cold water retained the gluten in Triticum aestivum (wheat) grains vis a vis when grains were not washed after boiling. Colonization of grains by mushroom mycelium was faster when these were treated with 2% CaSo4 + 2% CaCo3 + 0.5% plaster of paris after boiling as compared to when treated with 2% CaSo4 & 0.5% CaCo3. It took only 12 days to colonize one kg grains when incubated at 25°C.
