| الوصف: | Para minimizar os problemas relacionados à ocorrência de cianobactéria em águas destinadas ao consumo humano há necessidade de se realizar estudos de alternativas técnicas de tratamento com destaque aos biofilmes com potencial de degradação de microcistinas (MC). O presente trabalho teve como objetivo avaliar o potencial de degradação de MC pela bactéria Sphingosinicella microcystinivorans B9, diferentes cepas de leveduras e bactérias probióticas. O teste foi efetuado com extrato de MC e diferentes quantidades de biovolume e densidade celular dos microrganismos. Os tratamentos foram mantidos a 27ºC com rotação de 100 rpm e as amostras para análise de MC e contagem dos microrganismos foram retiradas após 0 e 96 horas de contato. A bactéria B9 apresentou maior degradação de MC, chegando a 98% após 96 horas.To minimize problems related to the occurrence of cyanobacteria in water for human consumption there is need to investigate alternative treatment techniques with emphasis on biofilms with the potential degradation of microcystins (MC). This study aimed to evaluate the potential degradation of MC by bacteria Sphingosinicella microcystinivorans B9, different strains of yeast and probiotic bacteria. The test was carried out with the extract obtained from strain Microcystis sp. In the tests biomass and cultures of microorganisms were used and the treatments were maintained at 27ºC with 100 rpm. Samples for analysis of MC and for counting the microorganisms were collected at 0 and 96 hours. The bacterium B9 presented the highest potential of degradation of MC reaching 98% after 96 hours. |
