Culturalable and non-culturable microorganisms naturally ferment majority of global fermented foods and beverages. Traditional food fermentation represents an extremely valuable cultural heritage in most regions, and harbors a huge genetic potential of valuable but hitherto undiscovered strains. Holistic approaches for identification and complete profiling(More)
The pH-neutral cell supernatant of Enterococcus faecalis BFE 1071, isolated from the feces of minipigs in Göttingen, inhibited the growth of Enterococcus spp. and a few other gram-positive bacteria. Ammonium sulfate precipitation and cation-exchange chromatography of the cell supernatant, followed by mass spectrometry analysis, yielded two bacteriocin-like(More)
Lactobacillus plantarum CNRZ 1228 exhibited heme-dependent catalase activity under environmental conditions similar to those encountered during sausage fermentation. The 1,455-bp catalase gene (katL) was cloned and encoded a protein of 484 amino acids. Expression of katL in a heterologous host showed that katL encodes a functional catalase. PCR screening of(More)
The aim of this study was to characterize dairy Lactobacillus plantarum-group strains on the basis of their phenotypic and genotypic profiles in order to increase the knowledge on the ecology and biodiversity within this wild Lactobacillus group. In addition, their in vitro potential probiotic properties were evaluated with a view to identifying potential(More)
On the basis of phenotypic and DNA-DNA reassociation studies, strain CCUG 34545T has been considered to represent a distinct Lactobacillus curvatus subspecies, Lactobacillus curvatus subsp. melibiosus. However, in several independent studies dealing with Lactobacillus sakei and L. curvatus strains, the subspecies division of L. curvatus has been found to be(More)
Enforced restrictions on the use of antibiotics as growth promoters (AGPs) in animal production have prompted investigations into alternative feed additives in recent decades. Probiotics are currently the main feed additive used in livestock. However, the selection of probiotic candidates relies on human-based methods and little is known about the(More)
A rich variety of indigenous fruits and vegetables grow in Africa, which contribute to the nutrition and health of Africa's populations. Fruits and vegetables have high moisture and are thus inherently prone to accelerated spoilage. Food fermentation still plays a major role in combating food spoilage and foodborne diseases that are prevalent in many of(More)
The functional features of Lactobacillus plantarum HAC01 (HAC01), isolated from fermented Korean kimchi, were studied with regard to the fat mass, immunometabolic biomarkers and dysbiosis in a diet-induced obesity (DIO) murine model. L. rhamnosus GG (LGG) served as reference strain and a PBS-treated group as control. The administration of L. plantarum HAC01(More)
Bacteriocins produced by lactic acid bacteria (LAB) are ribosomally synthesized antimicrobial peptides, with a diverse mode of bactericidal activity. This study focused on characterization of the bactericidal activity of bacteriocin ST8SH, with special attention to control of Listeria and Enteroccus species. Lactobacillus plantarum ST8SH produces a(More)
