De novo assembly of genomes from long sequence reads reveals uncharted territories of Propionibacterium freudenreichii

Propionibacterium freudenreichii is an industrially important bacterium granted the Generally Recognized as Safe (the GRAS) status, due to its long safe use in food bioprocesses. Despite the recognized role in the food industry and in the production of vitamin B12, as well as its documented health-promoting potential, P. freudenreichii remained poorly characterised at the genomic level. At present, only three complete genome sequences are available for the species.

In vitro assessment of antibiotic resistance pattern among lactobacillus strains isolated from goat milk

This study aimed to assess the antibiotic susceptibility of Lactobacillus strains of goat milk origin. Lactobacilli are generally recognized as safe, but can act as reservoir for genes carrying antibiotic resistance traits; which can further spread to commensal, food spoilage or pathogenic organisms. Lactic acid bacteria (LAB) strains coming from animal sources had significant interaction with antibiotics. Goat milk, being second to cow milk in production and due to its close resemblance to human milk composition, is among favorable source for isolating potential probiotic LAB strains.

Comparison of three Yarrowia lipolytica strains for lipase production: NBRC 1658, IFO 1195, and a local strain

Lipase production was examined with 3 strains of Yarrowia lipolytica: NBRC 1658, IFO 1195, and a local strain. All strains were obtained from Hacettepe University’s Department of Food Engineering. The addition of nitrogen and carbon sources and the effects of initial pH and temperature parameters were studied.
