In this work, a kinetic study of the extraction of phenolic compounds from the micelial biomass of Pleurotus ostreatus obtained by submerged fermentation of was carried out. The conversion factors from substrate to biomass (Yx/s), substrate to product (Yp/s) and biomass productivity (Px, and Pp) were calculated, with values of 0,39 g of biomass·g of glucose-1, 0,1 g of total phenols·g of glucose-1, 0,047 g of biomass·L-1 h-1 and 0,0006 g of phenols L-1 h-1, respectively. The growth data were adjusted to the Gompertz model with a coefficient of determination (R2) of 0,88, while the glucose consumption data adjusted better to a Logistic model with an R2of 0,95(p < 0,05). The kinetic parameters of the process were obtained, such as the specific growth rate (µ, 0.031 h-1) and the specific speed of glucose consumption (µg, 0,011 h-1). [ABSTRACT FROM AUTHOR]
