considering the emergence of antibiotic resistance, scientists are interested in using new antimicrobial agents in the treatment of infectious diseases including infections of the enteric systems. lactic acid bacteria have the great potential to produce antimicrobial compounds that inhibit and control pathogenic bacteria. the aim of this study was to determine the anti-bacterial and anti-adhere...
Lactobacillus delbrueckii subsp. bulgaricus CNRZ 397 (Lb. bulgaricus) is characterized by a high level of peptidase activities specific to proline-containing peptides. A prolidase (PepQ, EC 3.4.13.9) was purified to homogeneity and characterized as a strict dipeptidase active on X-Pro dipeptides, except Gly-Pro and Pro-Pro. The values for Km and Vmax were, respectively, 2.2 mM and 0.33 mmol min...
Lactobacillus delbrueckii subsp. bulgaricus (Lb. bulgaricus) is an important species of Lactic Acid Bacteria (LAB) used for cheese and yogurt fermentation. The genome of Lb. bulgaricus 2038, an industrial strain mainly used for yogurt production, was completely sequenced and compared against the other two ATCC collection strains of the same subspecies. Specific physiological properties of strai...
We previously reported that dissolved oxygen (DO) suppresses yogurt fermentation with an industrial starter culture composed of Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus) 2038 and Streptococcus thermophilus 1131, and also found that reducing the DO in the medium prior to fermentation (deoxygenated fermentation) shortens the fermentation time. In this study, we found that deoxyg...
Microbial analyses of fermented milk products require selective methods to discriminate between close species simultaneously present in high amounts. A culture-based method combining novel chromogenic agar media and appropriate incubation conditions was developed to enumerate lactic acid bacteria (LAB) strains in fermented milk. M1 agar, containing two chromogenic substrates, allowed selective ...
