Abstract:RESUMOMicrorganismos foram isolados de areia fenólica resultante de atividades metalúrgicas, utilizando meio mínimo para fungos e pentaclorofenol (PCF) como única fonte de carbono. Após quatro repiques sucessivos em intervalos de 15 dias de incubação, as culturas foram plaqueadas em meio de Martin. Três gêneros de fungos foram isolados e identificados como Acremonium sp., Paecilomyces sp. e Penicillium sp. Estes foram testados para degradar os corantes índigo e RBBR (Azul Brilhante de Remazol -R) e o organoclo… Show more
In this work, we isolated and identified filamentous fungi present in swine wastewater (SW) that are resistant and with the ability to remove atrazine removal. For the isolation, the SW was inoculated into liquid medium containing 0.01 and 0.1 g L-1 of atrazine and after the adaptation period, was transferred on solid medium containing 10 mg L-1 atrazine. Three strains of filamentous fungi were isolated and identified as Cladosporium cladosporioide, Rhizopus stolonifer and Penicillium purpurogenum. The isolates were tested for their ability to degrade atrazine in liquid medium containing 1.5 g L-1 of the herbicide as single source of carbon and nitrogen. In 15 days of culture, the isolated R. stolonifer showed a higher removal rate (73.75%), followed by P. purpurogenum (73.42%) and C. cladosporioides (68.42%), indicating a high possibility of using these microorganisms in the removal of atrazine in waters and effluents.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
