Five parental strains of Pediococcus were examined for plasmid content. Each strain contained three to six resident plasmids, ranging in size from 4.5 to 39.5 megadaltons. A bacteriocin-like substance produced by Pediococcus cerevisiae FBB63 was tentatively linked to a 10.5-megadalton plasmid after being cured with novobiocin.

Pediococci are found in foods and on plants and as beer-spoilage agents. The goal of the present study was to use the DNA sequences of the first three variable regions of the 165 rRNA gene, the 16S-23S rRNA internally transcribed spacer region sequence and approximately a third of the 60 kDa heat-shock protein gene to elucidate phylogenetic groupings within the genus Pediococcus. Phylogenetic t...

AIMS The possibility of substrate inhibition by glucose on biomass and pediocin production was studied in cultures of Pediococcus acidilactici on a residual medium. METHODS AND RESULTS Calculation of the substrate inhibition coefficient in the context of microbial growth is generally laborious, and very prone to experimental error. However, a simulation combining logistic and Monod kinetics e...

A medium using fish waste as substrate was designed for production of lipase by Enterococcus faecium MTCC 5695 and Pediococcus acidilactici MTCC 11361. Medium components and culture conditions (fish waste protein hydrolysate (FWPH) concentration, fish waste oil (FWO) concentration, pH, temperature, and fermentation time) which affect lipase production were screened using factorial (5 factors ∗ ...

This study was carried out to investigate the isolation and characterization of lactic acid bacteria (LAB) from naturally fermented sauce-type kimchi. Sauce-type kimchi was prepared with fresh, chopped ingredients (Korean cabbage, radish, garlic, ginger, green onion, and red pepper). The two isolated bacteria from sauce-type kimchi were identified as Pediococcus pentosaceus and Lactobacillus br...

Pediocin PD-1, produced by Pediococcus damnosus NCFB 1832, is inhibitory to several food spoilage bacteria and food-borne pathogens. However, pediocin PD-1 is not active against other Pediococcus spp. and differs in this respect to other pediocins produced by Pediococcus acidilactici and Pediococcus pentosaceus. Production of pediocin PD-1 starts during early growth and reaches-a plateau at the...

background: lactic acid bacteria (lab) isolated originally from sourdough are probably the best candidates as biopreservatives, because they are well adapted to the non-aseptic conditions in sourdough fermentation. the aim of the present study was to study antifungal properties of a dominant endogenous lab isolated from whole barley sourdough. methods: whole barley flour from a mixture of barle...

Pediococcus pentosaceus strain wikim 20 is a lactic acid bacterium that was isolated from kimchi, a representative traditional Korean fermented food. Here, we announce the complete genome sequence of P. pentosaceus strain wikim 20 consisting of a 1,830,629-bp chromosome and provide a description of its annotation.

Pediococcus acidilactici strain K3 is an alcohol-tolerant lactic acid bacterium isolated from nuruk, which is a traditional Korean fermentation starter for makgeolli brewing. Draft genome of this strain was approximately 1,991,399bp (G+C content, 42.1%) with 1525 protein-coding sequences (CDS), of which 44% were assigned to recognized functional genes. This draft genome sequence data of the str...

Pediococcus pentosaceus FBB61 and L7230, isolated from cucumber fermentations, produced a bacteriocin, designated pediocin A, which had identical activity spectra against species of Pediococcus, Clostridium, Staphylococcus, and Streptococcus. Both strains possessed a 13.6-megadalton plasmid (pMD136). Plasmid curing experiments suggested that both bacteriocin immunity and production determinants...
