Abstract: The objective of this experiment was to explore the effects of cellulose degrading bacteria on the fermentation quality of bamboo powder. In this experiment, Bacillus safensis and Cellulomonas iranensis which were isolated from termite guts were added to bamboo powder with a moisture content of approximately 70% for silage fermentation. The control group without any additives was labeled as CK. After 14 and 30 days of ensiling, silage-bags were opened and samples were taken, the fermentation quality and fiber composition of the bamboo powder were evaluated statistically. The results indicated that adding BS and CE could improve the fermentation quality of bamboo powder. Compared to the control group, the addition of BS and CE significantly reduced the pH value, coliform bacterial count, the content of crude fiber, the content of neutral detergent fiber and the content of acid detergent fiber. Therefore, this study provides theoretical support for the development of woody feeds, such as bamboo powder silage.

摘要: 为探究纤维素降解细菌对竹粉青贮饲料发酵品质的影响,本试验利用从白蚁肠道中筛选得到的沙福芽孢杆菌(Bacillus safensis, BS)和伊朗纤维单胞菌(Cellulomonas iranensis, CE)添加到含水量为70%左右的竹粉中进行青贮发酵,以未添加组作为空白对照(CK),在青贮14和30 d后开袋取样测定竹粉的发酵品质和纤维组分,发现添加沙福芽孢杆菌和伊朗纤维单胞菌均可以改善竹粉的发酵品质。与CK相比,添加沙福芽孢杆菌和伊朗纤维单胞菌能显著降低竹粉青贮的pH值、大肠杆菌数量、粗纤维、中性洗涤纤维和酸性洗涤纤维的含量。因此,添加沙福芽孢杆菌和伊朗纤维单胞菌有助于改善竹粉青贮发酵品质和促进纤维降解,为竹粉青贮等木本饲料的开发提供了理论支持。
