Summary: | This review article explores sustainable biotechnological strategies for converting sulfate compounds and lignocellulosic waste, focusing on using sulfate-reducing bacteria (SRB) and the valorization of agroforestry residues and sanitary sewage. SRB show potential in effluent treatment, mine drainage, and the removal of sulfate and heavy metals from wastewater, with their metabolic activity being influenced by factors such as pH, temperature, and chemical oxygen demand/sulfate (COD/SO4=) ratio. In the context of a sustainable bioeconomy, the challenge of converting lignocellulosic waste into value-added products is addressed through physical pretreatment techniques such as milling, extrusion, microwave irradiation, and ultrasound, which are efficient in valorizing waste from urban tree pruning. The article highlights the importance of bioreactors in transforming raw materials into desirable biochemical products, discussing different types of bioreactors, such as batch, continuous stirred tank, airlift, fluidized bed, upflow anaerobic sludge blanket (UASB), and bubble column, and their specific advantages and disadvantages. Sustainable sulfate reduction is the central focus, integrating the application of SRB and the conversion of lignocellulosic waste in a way that complements the objectives of the work and promotes a more cohesive flow in the summary. Thus, the interrelationship between effluent treatment strategies and waste valorization is emphasized from an environmental sustainability perspective, highlighting the relevance of this study in the broader context of a sustainable bioeconomy. |

As BRS demonstram potencial no tratamento de efluentes, drenagem de minas e remoção de sulfato e metais pesados de águas residuais, sendo sua atividade metabólica influenciada por fatores como pH, temperatura e relação demanda química de oxigênio/sulfato — DQO/SO4=. No contexto de uma bioeconomia sustentável, o desafio de converter resíduos lignocelulósicos em produtos de valor agregado é abordado por meio de técnicas de pré-tratamento físico, como moagem, extrusão, irradiação por micro-ondas e ultrassom, eficientes na valorização de resíduos de poda de árvores urbanas. O artigo destaca a importância dos biorreatores na transformação de matérias-primas em produtos bioquímicos, discutindo diferentes tipos de biorreatores, como batelada, tanque agitado contínuo, airlift, leito fluidizado, reator anaeróbio de fluxo ascendente (UASB) e coluna de bolhas, e suas vantagens e desvantagens específicas. A redução sustentável do sulfato é o foco central, integrando a aplicação de BRS e a conversão de resíduos lignocelulósicos de maneira a complementar os objetivos do trabalho e promover um fluxo mais coeso no resumo. Assim, enfatiza-se a inter-relação entre as estratégias de tratamento de efluentes e a valorização de resíduos em uma perspectiva de sustentabilidade ambiental, destacando-se a relevância deste estudo no contexto mais amplo de uma bioeconomia sustentável.Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)2024-03-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/175210.5327/Z2176-94781752Revista Brasileira de Ciências Ambientais (RBCIAMB); v. 59 (2024): RBCIAMB - ISSN 2176-9478; e1752Revista Brasileira de Ciências Ambientais (RBCIAMB); Vol. 59 (2024): RBCIAMB - ISSN 2176-9478; e17522176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESenghttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1752/947Copyright (c) 2024 Revista Brasileira de Ciências Ambientais (RBCIAMB)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPaiva, Gilka Maria da SilvaAraujo , Gleice Paula deLins, Ivan XavierCavalcanti, Davi de LimaSantos, Leonardo Bandeira dosBenachour, MohandSantos, Valdemir Alexandre dos2024-04-11T00:42:07Zoai:ojs.www.rbciamb.com.br:article/1752Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2024-04-11T00:42:07Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false |
