Mushroom cultivation is one of the efficient ways by
which residues can be recycled. P. ostreatus grown on
different substrates are nutritious with high protein,
fiber and low fat. It may also offer economic incentives
for agribusiness to examine these residues as valuable
resources and develop new enterprises to use them to
produce nutritious mushroom products. Therefore, the
mushroom cultivation may become one of the most
profitable agribusiness that could produce food products
from different substrates and help to dispose them in an
environment friendly manner.
Almost all producers use rice straw for the
production of P. osteratus, which is also one of the best
substrate in this study. Therefore, use of a variety of the
substrates is essential. Although the amount of yield is
lower than in rice straw, other substrates such as rice
straw plus wheat straw, rice straw plus paper and
sugarcane bagasse can also be used as alternative
substrates with supplement in the cultivation of P.
osteratus.
