Kombucha is sweetened black tea that is fermented by a symbiosis of bacteria and yeast embedded within a cellulose membrane. It is considered a health drink in many countries because it is a rich source of vitamins and may have other health benefits. It has previously been reported that adding lactic acid bacteria (Lactobacillus) strains to kombucha can enhance its biological functions, but in ...

Tauhe present work shows the relation between kefir fermentation ability and carbohydrate uptake rate. This was examined in a model system containing kefir co-culture and lactose in order to study fermentation induced by yeasts and bacteria at the same time. Lactose uptake rate was recorded by using (14)C-labelled lactose. The effect of lactose, cell concentration and pH on lactose fermentation...

The genus Corynebacterium includes Gram-positive species with a high G+C content. We report here a novel species, Corynebacterium kefirresidentii SB, isolated from kefir grains collected in Germany. Its draft genome sequence was remarkably dissimilar (average nucleotide identity, 76.54%) to those of other Corynebacterium spp., confirming that this is a unique novel species.

The aim of this study is to identify and characterise potential autochthonous functional starter cultures in homemade horsemeat sausage. The dominant microflora in the samples of horsemeat sausage were lactic acid bacteria (LAB), followed by micrococci. Among the LAB, Lactococcus lactis ssp. lactis and Lactobacillus plantarum were the dominant species, and since the first is not common in ferme...

The objective of this study was to identify lactic acid bacteria (LAB) isolated from kimchi and to evaluate its characteristics and functional properties for application in fermented dairy products as a probiotic or commercial starter culture. Eight stains isolated from kimchi were selected through an investigation of phenotypic characteristics. Two strains (DK211 and DK303) were identified as ...

Kefir is fermented milk with a slightly acidic taste obtained by incubating milk with kefir grains. These grains are white or lightly yellow gelatinous masses characterized by irregular forms, constituted by a complex mixture of lactococci, homofermentative and heterofermentative lactobacilli, yeasts and acetic acid bacteria living in a strong and specific symbiosis. This complex microflora is ...

Here, we summarize the composition and uses of Schizosaccharomyces pombe media and discuss key issues for consideration in the generation of S. pombe cultures. We discuss the concept of "culture memory," in which the growth state and stress experienced by a strain during storage, propagation, and starter culture preparation can alter experimental outcomes at later stages. We also describe the t...

Traditional preparation of African indigenous vegetables (AIVs) such as black nightshade (Solanum nigrum) and spiderplant (Cleome gynandra) involves either boiling discarding the first water or lengthy boiling. Fermentation is considered a better alternative processing technique due to enhanced retention phytochemical contents sensory properties. However, little known about impact lactic acid f...

UNLABELLED A method is described for growth of a Lactobacillus plantarum starter culture in jars of commercially available pasteurized fresh-pack kosher dill cucumbers so that jars can be used to inoculate commercial scale cucumber fermentation tanks. A procedure is also described to transfer lactic acid bacteria from frozen storage in MRS broth into cucumber juice and commercial jars of kosher...
