Growth and production of laccase enzymes of Pleurotus ostreatus during the degradation process of bisphenol a

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...

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. El Bisfenol A [4'4'-dihidroxi-2,2 difenilpropano] (BFA) es un compuesto orgánico utilizado en una amplia gama de productos de uso doméstico. EL BFA es considerado como un potente disruptor endócrino que pone en riesgo la salud humana. En esta investigación se evaluó el crecimiento de Pleurotus ostreatus en presencia de 50 y 75 mg/L de BFA en fermentación sumergida, evaluando la; velocidad específica de crecimiento (µ), biomasa máxima (Xmáx), consumo de glucosa, porcentaje (%) y constante de biodegradación (k) del BFA, actividad enzimática de lacasas (U/L), y algunos de sus parámetros cinéticos enzimáticos. Los valores más alto con respecto a los parámetros cinéticos de crecimiento y producción de lacasas, se obtuvieron en el medio con 75 mg/L de BFA. P. ostreatus mostró valores de pH neuro-básicos en los medios adicionados con BFA. El consumo de glucosa fue del 100 % en todos los medios. Durante las primeras 100 h de crecimiento, este hongo degradó más del 50 % de ambas concentraciones. Esta investigación es la primara en México que demuestra la eficiencia degradativa de P. ostreatus BE01 al degradar una concentración de BFA que no ha sido reportada anteriormente y que es superior a las reportadas en diversas matrices ambientales.
