ABSTRACT
With the world's focus on bio-fuel, cellulolytic microorganisms are being exclusively explored. In this paper, a strain of rod, NBG, was obtained from the rumen of Inner Mongolia sheep by an enrichment method with Whatman No.1 filter paper as the selective substrate. The strain was found to effectively degrade filter paper in solution. It was identified as Fibrobacter succinogenes based on DNA G + C mol %, together with morphological, physiological and biochemical tests. The endo-glucanase, -glucosidase and filter paper enzyme activity of NBG reached 62.5 ± 3.0 U•mL-1, 169.0 ± 9.4 U•mL-1 and 30.8 ± 5.4 U•mL-1, respectively, within 72 h of fermentation.
RESUMO
Com o foco mundial em biocombustíveis, microrganismos celuloliticos estão sendo exclusivamente explorados. Neste trabalho, uma cepa de bastão, NBG foi obtida do rumen de ovelhas do interior DA Mongolia com o método de enriquecimento e o papel de filtro No.1 como substrato seletivo. A cepa foi encontrada para degradar efetivamente o papel de filtro na solução. Foi identificado como Fibrobacter succinogenes baseado em DNA + c mol% juntamente com testes morofológicos, fisiológico e bioquímicos. A endo-glucanase e o papel de filtro chegaram com relação a atividade de enzima NBG 62.5 ± 3.0 U.ml-1, 169±9.4U.ml-1 e 30.8±5.4U.ml-1, respectivamente, com 72 horas de fermentação.
