| Abstract: | Pleurotus ostreatus mushroom mycelium was cultivated in submerged culture in shake-flask experiments with acid extract from peat and yeast extract
as nutrient sources. Different concentrations of water-diluted peat extract were tested in an attempt to overcome the effect
of growth inhibitors apparently present in nondiluted peat extracts. The best results were obtained with a ratio of one part
of peat extract diluted with one part of water. Several operating variables were studied to optimize the growth of mycelial
biomass ofP. ostreatus. The best results produced approximately 5 g/L dry biomass with a yield of 60% and an efficiency of 33%. These results were
obtained in 8 d at 5% (v/v) inoculum ratio, 28°C, pH of 5.0, and 150 rpm. |
