detection and characterization of weissellicin 110, a bacteriocin produced by weissella cibaria

background: weissellicin 110 is the only bacteriocin reported in weissella cibaria up to now. this bacteriocin represents several unique features. this is the first report on the gene sequence that encodes for the bacteriocin.objectives: providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives.material...

Purification and Characterization of Bacteriocin Produced by Weissella confusa A3 of Dairy Origin

A dramatic increase in bacterial resistance towards currently available antibiotics has raised worldwide concerns for public health. Therefore, antimicrobial peptides (AMPs) have emerged as a promisingly new group of therapeutic agents for managing infectious diseases. The present investigation focusses on the isolation and purification of a novel bacteriocin from an indigenous sample of cow mi...

Detection and activity of a bacteriocin produced by Leuconostoc mesenteroides.

Leuconostoc mesenteroides UL5 was found to produce a bacteriocin, referred as mesenterocin 5, active against Listeria monocytogenes strains but with no effect on several useful lactic acid bacteria. The antimicrobial substance is a protein, since its activity was completely destroyed following protease (pronase) treatment. However, it was relatively heat stable (100 degrees C for 30 min) and pa...
