bacteriocin 是什么意思

中文翻译与英英解释

n.
= bacillin.
Bacteriocins are proteinaceous toxins produced by bacteria to inhibit the growth of similar or closely related bacterial strain(s). They are typically considered to be narrow spectrum antibiotics, though this has been debated.

例句与用法

1.Isolation and purification of the bacteriocin are studied
优化后的抗菌活性明显增强。

2.Mode of action of plantaricin l - 1 , an antilisteria bacteriocin produced by lactobacillus plantarum
1对单核细胞增生李斯特氏菌作用机理的研究

3.A bacteriocin with a broad spectrum activity produced by grapevine crown gall biocontrol strain e
淀粉酶产生菌的分离鉴定及发酵条件与酶性质研究

4.Study on the isolated bacteriocin ' s property shows that the bacteriocin has good stability against temperature and ph . the antimicrobial activity is not influenced disposed for 10 minutes under 80 , and only 13 % loss of activity is suffered under the temperature of 100 for 10min
对分离出的细菌素的性质研究表明,细菌素具有较好的热稳定性和酸碱稳定性,在温度80处理10min对活性没有影响, 100处理10min活性仅损失13 ,在ph3 - 10的范围内活性变化不大。

5.In the research field of food preservation , an intense interest for scientists is focused on the isolation of antimicrobial substances from microbial metabolites . natural biopreservatives derived from traditional fermented foods are generally recognized as safe . in this paper , one strain screened for its safety and broad antimicrobial spectrum and its antimicrobial substance - - bacteriocin are studied in detail
本文从传统的发酵食品中筛选出一株安全、具有广谱抗菌活性的芽孢杆菌,并对其抗菌活性物质细菌素进行分析,为微生物天然生物防腐剂的开发以及在食品中的应用提供理论依据。

6.Two protein peaks can be obtained by bio - gel p - 6 chromatography and both peaks have antimicrobial activity . so the bacteriocin is consisted of two proteins with different mw . only one protein with larger mw can be detected through tricine - sds - page , and its mw is about 8 , 570da
采用30硫酸铵就能完全把发酵液中的细菌素全部沉淀,通过生物胶bio - gelp - 6层析发现细菌素被分离出两条抗菌蛋白峰,这表明r21 - 4产生的细菌素是由两种不同分子量的蛋白质组成的,通过tricine - sds - page检测,只能检测到一条分子量相对较大的细菌素,分子量在8 , 570da左右。

7.Antimicrobial effect of the bacteriocin produced by r21 - 4 is studied in the food systems . the results show that the conspicuous antimicrobial effect in the preservation of fresh milk . the samples were stored under 37 and the bacteria concentration in the sample with bacteriocin was 3 - 5 order less than the sample without bacteriocin
考察了r21 - 4产生的细菌素用有机溶剂萃取制备的方法及其在食品中的防腐效果,结果表明,细菌素在消毒鲜牛奶的保藏中具有明显的防腐效果,样品添加细菌素在37保存24h - 48h后与对照相比细菌总数相差3 - 5个数量级,防腐效果显著。
