In this study, the antibiotic resistance (AR) of lactic acid bacteria (LAB) isolated from traditional Turkish fermented dairy products was investigated. Yogurt, white cheese, tulum cheese, cokelek, camız cream and kefir as dairy products were collected from various supermarkets. Lactic acid bacteria such as Lactobacillus spp., Streptococcus spp., Bifidobacterium spp., and Enterecoccus spp. were...
Lactic acid bacteria are characterized as gram-positive, usually non-motile, non-sporulating bacteria that produce lactic acid as a major or sole product of their fermentative metabolism. In this study, the presence of lactobacilli were investigated in the intestines of beluga ( Huso huso) and Persian sturgeon ( Acipenser persicus ), inhabiting Caspian sea. The obtained data showed that various...
Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after exposure to propolis and cypermet...
Considerable advances have been made in the genetics and molecular biology of lactic acid bacteria, including Lactococcus, Lactobacillus, Leuconostoc, Pediococcus and Streptococcus spp. These have resulted in the construction of constitutive gene expression cassettes, inducible gene expression systems, and specific protein targeting systems for these bacteria. These developments are important i...
Gluconic acid reaches the large intestine to stimulate lactic acid bacteria. However, the fermentation pattern of gluconic acid has yet to be elucidated. Accordingly, we examined the fermentation properties induced by gluconic acid in the pig cecal digesta in vitro. We also tested sorbitol and glucose, substrates for which the fermentation rate and patterns are known. The gluconic acid-utilizin...
By applying non-sterile open fermentation of food waste, various thermotolerant l-lactic acid-producing bacteria were isolated and identified. The predominant bacterial isolates showing higher accumulation of l-lactic acid belong to 3 groups of Bacillus coagulans, according to their 16S rRNA gene sequence similarities. B. coagulans strains M21 and M36 produced high amounts of l-lactic acid of h...
Human breast milk contains potentially Probiotic lactic acid bacteria. Studies showed that this fluid has beneficial effects on the health of neonates. It is a complex species-specific biological fluid adapted to satisfy the nutritional requirements of the rapidly growing infants. These bacteria could protect the infant against infections and contribute to the maturation of the immune system. I...
