Rapid identification of shrimp bacterial pathogens by enzymatic amplification and digestion of 16S rRNA gene 用16SRRNA基因的内切酶图谱快速鉴别几种对虾病原菌
The results suggested that daidzein improved the level of serum testosterone and rumen bacterial digestion and metabolism in ruminates. 结果表明:大豆黄酮可以提高血清睾酮水平,并改善瘤胃微生物消化代谢。
If ultrasonic are applied as pretreatment to disintegrate the sludge flocs and disrupt bacterial cells 'wall, the hydrolysis can be improved a lot, so that the residence time can be shortened and the efficiency of anaerobic digestion be significantly increased. 在厌氧消化前,对污泥进行超声波预处理,使污泥细胞壁破裂,细胞内含物溶出,可以加速污泥的水解过程,从而达到缩短消化时间,提高消化效率的目的。
Bacterial genomic DNA samples were first digested by a group of selected restriction enzymes, separately. The resulting digests were then ligated to one of the three types of specially designed adapters corresponding to the restriction enzymes used for digestion. LPA法利用“酶切-连接-PCR”之组合,首先选定一组限制性内切酶,各自单独地酶切细菌总DNA样品,然后酶切产物分别与相应的寡聚核苷酸片段接头连接。
As functional feed, probiotics feed can adjust the bacterial colony balance in animal gut flora balance, so never produce resistance to drugs. It also has great palatability, high animal digestion rate and stable performance. 作为功能性饲料,益生菌饲料调节动物肠道菌落平衡,不产生抗药性,适口性好,动物消化率高且功能稳定。
