Researchers have used genomic sequence comparisons to predict an ocean bacterium’s trophic strategies, which may provide a technique to analyze the diversity of ocean bacteria, many of which are difficult to culture in the lab. Federico Lauro et al. compared the genomes of two common ocean bacteria: the copiotrophic Photobacterium angustum, which lives in warm, nutrient-rich waters and is fast ...

Résumé Characteristics of Lactic Acid Bacteria (LAB) isolated from rotifers, ~rachionus plicutilis, resembled those of Lactobacillus plantarum or Carnobacteriurn sp. It was investigated whether the artificial maintenance of a high concentration of LAB in rotifers might increase their dietary value for turbot larvae, particularly when the fish were infected with pathogenic Vibrio sp. One LAB str...

Humans and animals are increasingly being subjected to various probiotic formulations with the claim of providing a number of health benefits to the consumer. These formulations usually incorporate bacterial consortia comprising of mostly lactic acid bacteria (LAB). Recent studies have shown that strains found in different regions of the gut are genetically different from each other and may the...

BACKGROUND In vivo imaging of orally administered lactic acid bacteria (LAB) and commensal bacteria in mice is shown to provide information on the spatial and temporal distribution of bacteria in the gastrointestinal tract. The bacteria can be detected and monitored using bioluminescence or near-infrared fluorescence. RESULTS Fluorescence imaging of bacteria was established by expressing the ...

The natural populations of lactic acid bacteria (LAB) and silage quality pineapple residue were investigated in this study. A total 34 LAB strains originally isolated from characterized identified by phenotypic genotypic methods. These Gram-positive catalase-negative bacteria, which divided into four groups: Lactiplantibacillusplantarum (52.9%), Levilactobacillus brevis (14.7%), Lacticaseibacil...

Thrombosis is characterized by congenital and acquired procatarxis. Lactic acid bacteria-fermented soybean milk products (FS-LAB) inhibit hepatic lipid accumulation and prevent atherosclerotic plaque formation. However, the therapeutic efficacy of FS-LAB against thrombosis has yet to be investigated. In this study, FS-LAB were administered subcutaneously into the tails of rats, with the subsequ...

Bacteriocins are antibacterial proteins produced by bacteria that kill or inhibit the growth of other bacteria. Many lactic acid bacteria (LAB) produce a high diversity of different bacteriocins. Though these bacteriocins are produced by LAB found in numerous fermented and non-fermented foods, nisin is currently the only bacteriocin widely used as a food preservative. Many bacteriocins have bee...

Some lactic acid bacteria (LAB) are known as representative of probiotics. To screen LAB effective to enhance intestinal immunity, in the present study, we developed an accurate and convenient in vitro evaluation system using Peyer's patch cells (PP-cells) isolated from the mice intestine. We observed that the amount of immunoglobulin A (IgA) produced by PP-cells co-cultured with LAB was well c...

Cell free extracts of four strains of Lactic acid bacteria (LAB) viz. Lactobacillus. acidophilus, Streptococcus.cremoris, Lactobacillus bulgaricus –56 and Lactobacillus bulgaricus –57 inhibited growth of Vibrio alginolyticus in nutrient broth. The antagonism of LAB to Vibrio alginolyticus was further confirmed by streak plating wherein suppression of growth of Vibrio was obtained. Juveniles of ...

INTRODUCTION Ogi is a popular fermented cereal gruel consumed mainly in the western part of Nigeria. Traditionally, uncooked Ogi is normally administered to diarrhoea patients to reduce the frequency of stooling. This study was therefore undertaken to identify, quantify and determine the antimicrobial properties of lactic acid bacteria (LAB) isolated from Ogi. METHODS The Ogi samples (Yellow,...
