Standardized application of yeast bioluminescent reporters as endocrine disruptor screen for comparative analysis of wastewater effluents from membrane bioreactor and traditional activated sludge

Abstract: A standardized protocol is demonstrated for bioluminescent strains Saccharomyces cerevisiae BLYES, BLYAS and BLYR as high-throughput screening tools to monitor the estrogenic, androgenic and toxic potencies in wastewater. The sensitivity and reproducibility of the assay in wastewater monitoring was evaluated for 7 day semi-continuous batch reactor using activated sludge with hormones spiked raw sewage. Yeast bioluminescent assay successfully captured the rapid removal of estrogenic and androgenic activities in… Show more

“…The study suggests that adding biomass materials and appropriate aerobic conditions could facilitate the degradation of nonylphenol in sewage sludge. To monitor the estrogenic, androgenic and toxic potencies in wastewater, Wang et al (2015a) demonstrated a standardized protocol for bioluminescent strains Saccharomyces cerevisiae BLYES, BLYAS, and BLYR as highthroughput screening tools. The standardized protocol was applied for a year-long monitoring of the effluent of a wastewater treatment plant featuring parallel operated fullscale membrane bioreactor and traditional activated sludge treatment.…”

“…Presume-se que a degradação ocorra pelo aumento da capacidade de as bactérias utilizarem os estrógenos ou metabólitos como fonte de carbono e energia para o crescimento microbiano (PETRIE et al, 2014). A idade do lodo de até 10 dias parece exercer maior influência na remoção de compostos estrogênicos que períodos superiores a este (WANG et al, 2015). Conforme resultados observados por Wang et al…”

“…(2015), a remoção de atividade estrogênica em esgotos tratados por sistema de lodos ativados não pôde ser correlacionada aos parâmetros operacionais como demanda bioquímica de oxigênio, sólidos suspensos, tempo de detenção hidráulica e idade do lodo superior a 10 dias (WANG et al, 2015).…”
