| Samenvatting: | Bisphenol A [4'4'-dihydroxy-2,2 diphenylpropane] (BPA) is an organic compound used in a wide range of household products. BPA is considered as a powerful endocrine disruptor that puts human health at risk. In this investigation, evaluated the growth of Pleurotus ostreatus in presence of 50 and 75 mg/L of BPA in submerged fermentation, evaluating the; specific growth rate (µ), maximum biomass (Xmax), glucose consumption, percentage (%) and biodegradation constant (k) of BPA, enzymatic activity of laccase (U/L), and some of its enzymatic kinetic parameters. The highest values regarding the kinetic parameters of growth and laccase production were obtained in the medium with 75 mg/L of BPA. P. ostreatus showed neutral-basic pH values in the media added with BPA. Glucose consumption was 100% in all media. During the first 100 h of growth, this fungus degraded more than 50% of both concentrations. This research is the first in Mexico that demonstrates the degradative efficiency of P. ostreatus BE01 by degrading a concentration of BPA that has not been previously reported and is higher than those reported in various environmental matrices. |
