Identificação das bactérias intestinais da traça-cera
Resumo
Globalmente, o uso de polímeros industriais de fontes de combustíveis fósseis é praticamente inevitável devido à diversidade de aplicações; porém, os problemas ambientais e ambientais que estão levando à busca de alternativas que permitam reduzir o uso destes, bem como estratégias para controlá-los por meio da degradação, com a participação de alguns agentes ativos bioorgânicos. Os insetos são de interesse, como possíveis biodegradantes devido à ação de bactérias no trato digestivo. Levando em consideração esses antecedentes, este estudo teve como objetivo identificar as bactérias presentes no intestino das larvas da traça-cera (Galleria mellonella). Trinta larvas foram alimentadas com dieta de isopor y trinta larvas em dieta natural por um período de 7 dias. Posteriormente, as larvas foram retiradas para estudo do trato gastrointestinal por PCR. Resultados obtidos mostraram a presencia de células bacterianas de Carnobacterium maltaromaticum, Brevibacterium sandarakinum, Pseudomonas psychrophila, Pseudomonas sp., Providencia sp., Corynebacterium sp. Porém, é necessário verificar a real ação isolada desses grupos de bactérias na degradação efetiva dos polímeros.
