Diversidade bacteriana associada à biodegradação de resíduos sólidos urbanos

Abstract: RESUMO O conhecimento das populações bacterianas responsáveis pela biodegradação dos resíduos sólidos dispostos em aterros sanitários pode levar ao desenvolvimento de alternativas tecnológicas viáveis para o tratamento e a estabilização dos resíduos, resultando em impactos positivos para a operação de aterros, a recuperação de energia, a saúde pública e o meio ambiente. O objetivo deste trabalho foi caracterizar a diversidade bacteriana associada à biodegradação de resíduos sólidos urbanos (RSU) aterrados em u… Show more

“…There are several mechanisms by which bacteria precipitate calcium carbonate; some are applied in concrete for crack healing (MONDAL; (DEY) GHOSH, 2019). Bacteria of the genus Bacillus can synthesize enzymes (AIRES et al, 2020). Precipitation via ureolysis involves the synthesis of the enzyme urease using the bacterial metabolism in the formation of ammonia (NH 3 ) and dissolved inorganic carbon (DIC) (according to Equation 1) and causes an increase in alkalinity in the bacterial cells (Equations 2 and 3).…”
