Abstract EN
Staphylococcus aureus and its drug-resistant strains, which threaten public health and food safety, are in need of effective control by biopreservatives.
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 that pentocin JL-1 has a molecular mass of 2987.23 Da.
Only six of the twenty-five amino acids could be identified by Edman degradation.
This bacteriocin is thermostable and tolerates a pH range of 5–7.
Also, it is sensitive to proteinase K, trypsin, pepsin, and alkaline protease.
This bacteriocin has a broad inhibitory spectrum against both Gram-positive and Gram-negative strains and in particular is effective against multidrug-resistant S.
aureus.
Additionally, we showed that the cell membrane is the target of pentocin JL-1 against methicillin-resistant S.
aureus (MRSA), causing a loss of proton motive force.
Furthermore, pentocin JL-1 has a drastic impact on the structure and integrity of MRSA cells.
These results suggest that pentocin JL-1 has potential as a biopreservative in the food industry.
