Comparative analysis of the exopolysaccharide biosynthesis gene clusters from four strains of Lactobacillus rhamnosus.
This is believed to be the first report demonstrating that the sequence, original organization and transcription of genes encoding EPS production are highly similar among four strains of Lb. Expand
Production of Exopolysaccharide by Lactobacillus rhamnosus R and Analysis of Its Enzymatic Degradation during Prolonged Fermentation
The decrease in viscosities and molecular weights of EPS withdrawn at different cultivation times permitted us to suspect the presence of a depolymerizing enzyme in the fermentation medium, and the loss of viscosity was increased up to 33%. Expand
Improvement of texture and structure of reduced-fat Cheddar cheese by exopolysaccharide-producing lactococci.
Exopolysaccharide-producing strains could contribute to the modification of cheese texture and microstructure and thus modify the functional properties of reduced-fat Cheddar cheese. Expand
Molecular analysis of bacterial population structure and dynamics during cold storage of untreated and treated milk.
New microbial species which can develop during cold storage after milk treatment are shown and contributes to identifying causes of reduced shelf life and deterioration of technological properties of milk during storage. Expand
MICs of Mutacin B-Ny266, Nisin A, Vancomycin, and Oxacillin against Bacterial Pathogens
The results indicate that nisin A and mutacin B-Ny266 are as active as vancomycin and oxacillin against most of the strains tested. Expand
Comparison of exopolysaccharide production by strains of Lactobacillus rhamnosus and Lactobacillus paracasei grown in chemically defined medium and milk
Exopolysaccharide (EPS) production was compared among three strains of lactobacilli. Lactobacillus rhamnosus strain 9595M can be classified among the highest EPS-producing strains of lactic acidExpand
Purification and structure of mutacin B‐Ny266: a new lantibiotic produced by Streptococcus mutans
Mutacin B‐Ny266 belongs to the type A lantibiotics and the proposed sequence is: F–K– –W–U–F– – –P–G– –A–K-O–G – –F–N– –Y– . Expand
Note : Genetic and biochemical characterization of nisin Z produced by Lactococcus lactis ssp. lactis biovar. diacetylactis UL 719
The bacteriocin produced by Lactococcus lactis ssp. lactis biovar. diacetylactis UL 719 was purified and characterized. Two peaks exhibiting antimicrobial activity were obtained after purification.Expand
Molecular characterization of three plasmids from Bifidobacterium longum.
Bifidobacterial plasmids were divided into five groups based on Rep amino acid sequence homology and the results suggest a new plasmid family for B. longum. Expand
Comparison of the activity spectra against pathogens of bacterial strains producing a mutacin or a lantibiotic.
Results indicate that many of the mutacins, especially those of groups A, B, C, D, I, J, K, L, M, and T, could be candidates for further development as useful antibiotics. Expand
