The objectives of this paper were production of probiotic yoghurt using L. paracasei ssp. tolerans, and evaluation of pH changes, viable counts, and organoleptic properties of the produced yoghurt. It was observed that the pH decrease during the fermentation period was faster in the milk inoculated with L. paracasei ssp. tolerans plus starter culture. There was a gradual decrease in pH in both ...

BACKGROUND Lactococcus lactis is industrially employed to manufacture various fermented dairy products. The most cost-effective method for the preservation of L. lactis starter cultures is spray drying, but during this process cultures encounter heat and oxidative stress, typically resulting in low survival rates. However, viability of starter cultures is essential for their adequate contributi...

One exciting area that has emerged through genetic analysis of the lactococci is the definition and practical application of gene systems that provide phage resistance to these industrially important bacteria. Naturally occurring phage-insensitive strains have been characterized and found to harbour multiple defence systems which can act at different points of the lytic cycle to prevent the suc...

Specific strains of the apathogenic coagulase-negative species Staphylococcus carnosus are frequently used as meat starter cultures, as they contribute to color formation and the production of aroma compounds. Here, we report the complete genome sequence of S. carnosus LTH 3730, a strain isolated from a fermented fish product.

Functional lactic acid bacteria (LAB) as starter cultures used in sourdough fermentation have been researched for years. This study evaluated the LAB strains Leuconostoc citreum DCM65 (mannitol, exopolysaccharide producing, antifungal activity) and Lactiplantibacillus plantarum subsp. MA418 (amylolytic their potential single or co-culture starters fermented buns containing different levels of s...

A FK506 analogue containing a non-natural starter unit was obtained through mutasynthesis by feeding cultures of Streptomyces sp. KCTC 11604BP fkbO deletion mutant with 3-cyclohexene-1-carboxylic acid. The structure of the new compound, 32-dehydroxy-FK506, and its biological activities were determined.

Morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (LAB), isolated from traditional yoghurts produced by tribes of Iran. From 60 yoghurt samples, a total of 137 LAB isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. Biochemical tests showed the occurrence of 9.76% mesophilic ho...
