菠萝渣纤维素降解菌的筛选及鉴定

摘要

In order to accelerate the fermentation of pineapple residue, various cellulose degrading-bacteria were isolated from naturally fermented pineapple residue by using manifold selective media, and obtained a pineapple residue cellulose degrading strain c3bl-3 through preliminary and repeated screenings with optimal medium of protein cellulose medium (PCS).It was identified as Chryseobacterium sp.according to its morphology, physiology, bio-chemical and molecular characteristics.%为了加快菠萝渣快速发酵,通过利用多种选择性培养基,从自然发酵的菠萝渣中分离到多种纤维素分解菌,经过初筛和复筛,获得了降解菠萝渣纤维素的菌株c3b1-3,其最适合的培养基为蛋白纤维素培养基;通过形态、生理生化特征和分子综合鉴定得出c3b1-3为金黄杆菌属(Chryseobacterium sp.).
