滤纸平板法结合摇床培养筛选到２个纤维素分解能力较强的混合菌Ｍ１和Ｍ２。在以纤维素为碳源的培养液中，２８℃振荡培养４ｄ，滤纸纤维素失重率分别达５７．５３％和５４．９２％，未经处理的稻草秆纤维素失重率为３８．８２％和３６．２１％。膨化稻草比稻草秆易分解，纤维素降解率可达６８．８３％和６０．０２％。经初步鉴定，Ｍ１由木霉Ｆ１和芽孢杆菌Ｂａ组成，Ｍ２由木霉Ｆ２和芽孢杆菌Ｂａ组成。实验结果表明，由真菌、细菌组成的混合菌分解纤维素的能力明显强于其中任何一个单一菌株。
Filter paper plate method combined with shaker culture to filter out two cellulose decomposition strong mixed bacteria M1 and M2. In the medium with cellulose as carbon source, the weight loss rate of cellulose in filter paper reached 57.53% and 54.92% respectively after shaken at 28 ℃ for 4 days. The weight loss rate of untreated rice straw was 38.82% And 36.21%. Expanded straw was more easily decomposed than straw, the degradation rate of cellulose reached 68.83% and 60.02%. After preliminary identification, M1 consists of Trichoderma F1 and Bacillus Ba, M2 consists of Trichoderma F2 and Bacillus Ba. The experimental results show that the ability of the mixed bacteria composed of fungi and bacteria to decompose cellulose is obviously stronger than any one of them.
