In order to improve
the degradation efficiency of lignocellulose
while increasing the yield of mushrooms, white rot fungi treatment
(Pleurotus ostreatus, Pleurotus eryngii, and Pleurotus geesteranus) combined with ammonia fiber expansion was proposed as a method
for treating lignocellulose (Pennisetum sinese, salix chips, and pine chips) for mushroom cultivation. Compared
with treatment using either ammonia fiber expansion or white rot fungus,
the combined treatment significantly improved lignocellulose degradation
rate by 10–20% and reduced the time required significantly.
Among them, P. geesteranus was the
most effective bacterium for the combined treatment of lignocellulose.
Ammonia fiber expansion-treated lignocellulose contributed to mycelial
growth and increased the activity of three lignin hydrolase enzymes
(laccase, manganese peroxidase, and lignin peroxidase) and mushroom
yield. The mushroom yield was increased by 44.6%. The combined treatment
method proposed in our study improves lignocellulose resource utilization
and is therefore useful in the treatment of agricultural solid organic
waste.
