Abstract:
Substrate for cultivating Pleurotus ostreatus was prepared by soaking it in water containing 0.5&percent; lime with no further thermal treatment. Five substrates were used: grass (Digitaria decumbens), corn cob, corn straw and two mixtures of corn straw or grass with coffee pulp. Immersion time varied between 0-48 h. Mushroom yield measured as biological efficiency varied between 37.3 and 126&percent;. No fungal contamination was found, however certain group of bacteria like pseudomonads, bacilli and coliforms were detected. This technique seems to have potential; however good control of the moisture of the substrate must be maintained to limit proliferation of substrate bacteria.
