fective paddy straw pasteurization,
a pasteurizer was developed and its

was pasteurized after soaking in
normal water and without soaking.
Different temperature-time combi

used. Substrate obtained was used
to cultivate three commonly culti

efficiency of 93.8 %, respectively.
Contamination was absent when
straw was pasteurized at 80 ºC for 2
h under maximum compression
