Screening identification and properties of a strain of thermophilic bacterium with strong degradation ability(Chinese)
-
摘要: 从高温堆肥物料中通过平板培养法分离、纯化并筛选出一株高效高温菌YB16.YB16具有同时分解淀粉、蛋白质、油脂和纤维素等大分子有机物的能力.经鉴定YB16为革兰氏阳性，杆状，有芽孢，好氧， G+Cmol%为50.66%，初步鉴定YB16属于芽孢杆菌属.pH生长范围为6.0～9.0，最适生长温度为65 ℃左右.Abstract: A strain of thermophilic bacterium with strong degradation ability named YB16 was plate-screened from thermophilic compost materials. The selected strain can decompose organic macromolecules such as starch, protein, lipid and cellulose simultaneously. YB16 was aerobic, Gram positive, rod, and formed spore and capsule. The results of DNA UV absorbency showed that G+C mol% of YB16 was about 50.66%. It was considered to be a variety of Bacillus sp. YB 16 grew well at pH6.0～9.0. The optimal growth temperature was about 65 ℃.
