Dextran a polymer of glucose is produced by different microorganisms like Leuconostoc mesenteroides, Lactobacillus sps, Streptococcus mutants, Weissella confusa etc. It has a wide range of applications in the food, pharmaceuticals and other industries. It also has significant role in green synthesis of silver nanoparticles. In the present study an efficient low molecular dextran produced by an ...

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,...

A total of 119 lactic acid bacteria (LAB) were isolated, by culture-dependant method, from rhizosphere samples of olive trees and desert truffles and evaluated for different biotechnological properties. Using the variability of the intergenic spacer 16S-23S and 16S rRNA gene sequences, the isolates were identified as the genera Lactococcus, Pediococcus, Lactobacillus, Weissella, and Enterococcu...

The genome of Weissella oryzae SG25T was recently sequenced and a botulinum neurotoxin (BoNT) like gene was identified by bioinformatics methods. The typical three-domains organization of BoNTs with a N-terminal metalloprotease domain, a translocation and a cell binding domains could be identified. The BoNT family of neurotoxins is rapidly growing, but this was the first indication of the possi...

Dextran a bacterial exopolysaccharide and a polymer of glucose is produced by different microorganisms like Leuconostoc mesenteroides, Lactobacillus spp, Streptococcus mutans, Weissella confusa etc. It has a wide range of applications in the food, pharmaceutical and other industries. Dextran and its derivatives like iron dextran, clinical dextran, food grade dextran are rapidly emerging as new ...

Dextran a bacterial exopolysaccharide and a long chain polymer of glucose is produced by different microorganisms like Leuconostoc mesenteroides, Lactobacillus spp, Weissella spp and Streptococcus mutans. It has a wide range of application in the food, pharmaceutical and other industries and so is emerging as new and industrially significant product. In the present study the cells of Weissella ...

Growth behavior of five lactic acid bacteria previously isolated from Persian sturgeon (Acipenser persicus), were evaluated at different pH, temperature and salt concentrations. Also, antibacterial activity of extracellular products (ECPs) of this LAB were assessed to Aeromonas hydrophila . Further, their antibiotic susceptibility was determined with some commonly used antibiotics in aquacultur...
