“…In DF, where specific microorganisms are desired to have the higher metabolic activity for production of biohydrogen, a high COD concentration could disrupt the microbial community dynamics. This possible disruption may lead to growth inhibition, decreased metabolic activity, and low production yields [42]. Additionally, the sugarcane vinasse showed a high concentration of polyphenols, which are toxic for the anaerobic microorganisms [33].…”

“…Máca & Dohányos, 2012) cujo estudo mostrou que sistemas com maiores concentrações de amônia toleram maiores concentrações de AGV, garantindo uma faixa de pH adequada para a atividade bacteriana. De qualquer forma, assim como os AGV, a amônia não apresenta toxicidade para os microrganismos, mas seu acúmulo no sistema pode levar à inibição da ação bacterianaDuan, et al, 2016; Venkiteshwaran et al, 2016).Sabendo que o acúmulo de produtos intermediários pode afetar a eficiência do tratamento anaeróbio, a carga orgânica deve ser controlada nos reatores(Pouresmaeil, Nosrati & Ebrahimi, 2019) Pouresmaeil et al, (2019). estudaram a digestão anaeróbia de vinhaça, e constataram que a produção de hidrogênio aumentava a partir do aumento do substrato até uma concentração de 11,60g DQO/L.…”
