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...
متن کاملIdentification and Characterization of a Bacteriocin-Like Substance, Produced by Leuconostoc mesenteroides, as a Bio-Preservative Against Listeria monocytogenes
By conducting a systemic screening from Chinese traditional Tofu, a bacteriocin producer with broad antimicrobial spectrum was found. The producer was identified by 16S rDNA sequencing, and it was identified as Leuconostoc mesenteroides. The producer possessed typical bacteriocin traits, such as be heat-stable and proteinase-labile. Its inhibition spectrum contained many distantly related gener...
متن کاملDetection 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. Materi...
متن کاملCharacterization of the Dextran Produced by Leuconostoc mesenteroides from Date Fruit Extract
In the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium Leuconostoc mesenteroides NRRL B512 (f) was investigated. In comparison to blue dextran (Mw≈2000 Da), dextran molecular weight was reduced (Mw2000 KDa). Flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concen...
متن کاملNosocomial Outbreaks Caused by Leuconostoc mesenteroides subsp. mesenteroides
From July 2003 through October 2004, 42 patients became infected by strains of Leuconostoc mesenteroides subsp. mesenteroides (genotype 1) in different departments of Juan Canalejo Hospital in northwest Spain. During 2006, 6 inpatients, also in different departments of the hospital, became infected (genotypes 2-4). Parenteral nutrition was the likely source.
