dc.description.abstract | Rice husk is a waste generated in large quantities in various countries, although its
reuse is limited due to low nutritional quality and high silica content. Therefore, this
study sought to evaluate using raw or carbonized rice husks to partially substitute
eucalyptus sawdust in substrates to produce the edible mushroom Pleurotus ostreatus.
The substrates were formulated with proportions of 0 to 100% of eucalyptus sawdust
and raw or carbonized rice husks. P. ostreatus was grown for 90 days on the substrates
to evaluate mycelial growth, fresh mass production, biological efficiency, and protein
and fat content. The organoleptic quality of the mushrooms produced was evaluated
by sensory analysis. The substrates’ moisture, pH, and C and N contents were
evaluated before and after cultivation. The substrates with 25 and 50% of raw or
carbonized rice husk in a mixture with sawdust provided nitrogen and water more
adequately to the fungus, improving the fresh mass production, the protein content of
mushrooms, and biological efficiency (75–83%) compared to the reference substrate
(100% eucalyptus sawdust), without altering the sensory quality. Given the
environmental issues caused by carbonization, using raw rice husk in a mixture of up
to 50% eucalyptus sawdust is recommended for P. ostreatus production. | |
