Methods Chromosome DNA was isolated from Bacillus natto . The pro nattokinase gene was then amplified from chromosome by PCR.
方法从纳豆芽胞桿菌中分离纯化基因组DNA ,作为模板通过PCR扩增纳豆激酶原基因。
It was concluded that Bacillus natto was an excellent microbial feed additive.
结果提示,纳豆芽孢桿菌是优良的饲用微生物添加剂。
The results showed that Bacillus natto could inhibit not only some kinds of gram positive and gram negative bacteria, but also some kinds of yeasts and moulds.
结果表明,纳豆菌具广谱抗菌作用,对细菌、酵母菌和霉菌皆有一定的拮抗作用。
