A novel bacteriocin, pentocin JL-1, produced by Lactobacillus pentosus that was isolated from the intestinal tract of Chiloscyllium punctatum, was purified by a four-step chromatographic process. Mass spectrometry based on MALDI-TOF indicated …

Pentocin JL-1, a Novel Bacteriocin Isolated from Lactobacillus pentosus , against Drug-Resistant Staphylococcus aureus HanJiang,JiongZou,HuiCheng,JiehongFang,andGuangrongHuang

2017年11月29日 · In our study, we aimed to purify and characterize pentocin JL-1, which was produced by Lactobacillus pentosus isolated from the intestinal tract of Chiloscyllium punctatum, exhibiting a broad inhibitory spectrum. This bacteriocin can inhibit not only MRSA but also other multidrug-resistant S. aureus strains.

2018年3月27日 · Pentocin MQ1 is a novel bacteriocin isolated from L. pentosus CS2 of coconut shake origin. The purification strategy involved adsorption-desorption of bacteriocin followed by RP-HPLC. It has a molecular weight of 2110.672 Da as determined by MALDI-TOF mass spectrometry and a molar extinction value of 298.82 M −1 cm −1. Pentocin MQ1 is not ...

2018年3月26日 · We report for the first time membrane permeabilization as a mechanism of action of the pentocin from the study against Gram-positive bacteria. Pentocin MQ1 is a cell wall-associated bacteriocin. Application of pentocin MQ1 improved the microbiological quality and extended the shelf life of fresh banana.

2017年11月29日 · A novel bacteriocin, pentocin JL-1, produced by Lactobacillus pentosus that was isolated from the intestinal tract of Chiloscyllium punctatum , was purified by a four-step chromatographic process.

2021年7月23日 · Pentocin ZFM94 performed activity against Gram-positive bacteria, Gram-negative bacteria, and fungi, especially for S. aureus D48, M. luteus 10209, and E. coli DH5α. Many pentocins produced from L. pentosus also can inhibit a variety of Gram-positive bacteria, Gram-negative bacteria, and the fungi Candida albicans ( 27 ).

2008年8月1日 · Lactobicillus pentosus 31-1, isolated from Chinese traditional ham, produced a bacteriocin active against Gram-positive bacteria including Listeria spp. The bacteriocin, named pentocin 31-1, has been purified by ammonium sulphate precipitation, SP-Sepharose Fast Flow and SDS–PAGE.

2017年11月29日 · Pentocin JL-1 has potential as a biopreservative in the food industry and is effective against multidrug-resistant S. aureus and has a drastic impact on the structure and integrity of MRSA cells. Staphylococcus aureus and its drug-resistant strains, which threaten public health and food safety, are in need of effective control by biopreservatives.

2010年2月1日 · Pentocin 31-1 was produced by Lactobacillus pentosus 31-1, isolated from the traditional China fermented Xuan-Wei Ham. In this work, study on its application as biopreservative in chill-stored nonvacuum-tray-packaged pork meat was carried out. Pentocin 31-1 was prepared by pH-adsorption in 5 l stainless steel fermentor.
