Efeito de linhagens de Fusarium oxysporum antagonistas em grupos funcionais de bacterias do solo

Abstract

Linhagens de Fusarium oxysporum antagonistas estao sendo utilizadas na Italia para o controle biologico de Fusarium spp., em diversas culturas, especialmente em condicoes de estufa. O presente trabalho teve como objetivo conhecer as interacoes entre as linhagens antagonistas, geneticamente manipuladas ou nao, e grupos funcionais de bacterias do solo, envolvidas no ciclo do carbono e do nitrogenio. Foram avaliados tres solos agricolas da regiao de Albenga (norte da Italia), sendo dois solarizados e o outro nao, e um solo cultivado com Popolus por dez anos da regiao de Carignano (norte da Italia). Nao foram observadas diferencas significativas, apos a introducao dos antagonistas, quando foram avaliados os efeitos nos grupos funcionais: amonificadores, oxidadores de nitrito e amonia, fixadores nao simbiontes aerobicos e anaerobicos de nitrogenio e denitrificadores, pelo metodo do numero mais provavel. Tambem nao foram observados efeitos em bacterias amiloliticas, proteoliticas, celuloliticas, pectinoliticas e bacterias totais, atraves do metodo de contagem de colonias em meio de cultura seletivo.
