BACKGROUND Panax ginseng is a physiologically active plant widely used in traditional medicine that is characterized by the presence of ginsenosides. Rb1, a major ginsenoside, is used as the starting material for producing ginsenoside derivatives with enhanced pharmaceutical potentials through chemical, enzymatic, or microbial transformation. METHODS To investigate the bioconversion of ginsen...

Lactobacillus sakei subsp. carnosus was predominant in the spoilage flora of sliced, vacuum-packed, smoked, oven-cooked turkey breast fillets which developed mild, sour spoilage flavors after 4 weeks storage at 4 degrees C. In contrast, Leuconostoc mesenteroides subsp. mesenteroides predominated in the spoilage flora of sliced, vacuum-packed, unsmoked, boiled turkey breast fillets from the same...

Kimchi, a traditional food in the Korean culture, is made from vegetables by fermentation. In this study, metagenomic approaches were used to monitor changes in bacterial populations, metabolic potential, and overall genetic features of the microbial community during the 29-day fermentation process. Metagenomic DNA was extracted from kimchi samples obtained periodically and was sequenced using ...

BACKGROUND An adaptive-network-based fuzzy inference system (ANFIS) was compared with an artificial neural network (ANN) in terms of accuracy in predicting the combined effects of temperature (10.5 to 24.5°C), pH level (5.5 to 7.5), sodium chloride level (0.25% to 6.25%) and sodium nitrite level (0 to 200 ppm) on the growth rate of Leuconostoc mesenteroides under aerobic and anaerobic condition...

Leuconostoc mesenteroides is a member of lactic acid bacteria (LAB) with wide applications in the food and medical industries. Species in the genus Leuconostoc are catalase-negative and generally regarded as facultative anaerobic or aerotolerant organisms. Despite their extensive use in industry, certain issues concerning the aerobic life of L. mesenteroides, e.g., the mechanism involved in the...

A Leuconostoc mesenteroides ssp. mesenteroides was isolated from goat's milk on the basis of its ability to inhibit the growth of Listeria monocytogenes. The antimicrobial effect was due to the presence in the culture medium of a compound, named mesentericin Y105, excreted by the Leuconostoc mesenteroides Y105. The compound displayed known features of bacteriocins from lactic acid bacteria. It ...

In a previous study it was observed that Leuconostoc citrovorum 8081 failed to grow on a synthetic medium adequate for the growth of Leuconostoc mesenteroides P-60 and other common assay organisms (1). However, the addition to the medium of certain extracts from liver permitted excellent growth of L. citrovorum. Similarly, folic acid stimulated growth of the organism but the amounts necessary w...

In 4 M guanidine hydrochloride (GdnHCl), the dimeric enzyme glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides (G6PD) dissociated to subunits and was extensively unfolded. Rapid dilution of this high GdnHCl concentration allowed G6PD to partially renature, as measured by enzyme reactivation, to a level which depended on the conditions employed. The fraction of the enzyme which did...

Here, the genome sequences of Lactococcus lactis subsp. lactis bv. diacetylactis FM03 and Leuconostoc mesenteroides FM06, both isolated from cheese, are presented. FM03 and FM06 contain 7 and 3 plasmids, respectively, that carry genes encoding functions important for growth and survival in dairy fermentations.

The recent literature contains numerous references to the use of partially hydrolyzed dextrans as plasma substitutes (Bull et al., 1949; Thorsen, 1949). Because of this interest, and as part of a general study of bacterial polysaccharide synthesis, the nutritional requirements of the major dextran forming organisms, Leuconostoc mesenteroides and L. dextranicum, are being investigated (Whiteside...
