Efeito da aplicação de nitrato na redução biogênica de sulfeto sob diferentes concentrações iniciais de bactérias redutoras de nitrato e sulfato

Abstract: . The effect of sodium nitrate application in the reduction of biogenic sulphide was evaluated through a 2 k complete factorial design, using as variable response the production of sulfide at intervals of incubation of 7, 14 and 28 days. The most effective condition for reducing the sulphide production (final concentrations from 0.4 to 1.6 mg S 2-L -1) was obtained with an initial population of sulphate-reducing bacteria and nitrate-reducing bacteria of 10 4 MPN mL -1 and 427.5 mg L -1 nitrate. The results als… Show more

“…This molecule can penetrate the plasma membrane and react with cellular components within the cytoplasm of microorganisms. In addition, it causes serious damage to oil production systems 3,35,49 . Besides hydrogen sulfide, other toxic metabolites can be produced such as: enzymes, exopolysaccharides, organic and inorganic acids, and ammonia 50 .…”

“…O processo de formação de um biofilme ocorre em cinco estágios, iniciando pela migração, seguida da adesão (que pode ser irreversível e reversível), colonização, amadurecimento e dispersão (VASCONCELOS et al, 2020). Ademais, cada um desses estágios pode ser interrompido empregando diferentes métodos, físicos (YU et al, 2020), químicos (BUSANELLO et al, 2018 e biológicos (SOUSA et al, 2010), bem como a associação entre eles (SAGGU et al, 2019). Esta minirrevisão lista alguns desses métodos, visando o controle do crescimento de biofilmes, em termos da saúde humana, como produto ao final da disciplina sobre o tema, elaborado por discentes do Programa Brazilian Journal of Development, Curitiba, v.8, n.12, p. 78646-78664, dec., 2022 de Pós-Graduação em Biologia Celular e Molecular da Universidade Federal da Paraíba, em outubro de 2022.…”
