We identified Lactobacillus isolates from Japanese women and newborn infants by a DNA-DNA hybridization method. The predominating lactobacilli were Lactobacillus crispatus and Lactobacillus gasseri in the women's vaginas and the newborns' intestines and L. gasseri and Lactobacillus fermentum in the women's intestines. All L. crispatus strains were exclusively strong H2O2 producers.
The diversity of lactic acid bacteria associated with Hussuwa fermentation, a Sudanese fermented sorghum food, was studied using a polyphasic taxonomical approach. Predominant strains could be well characterised based on a combination of phenotypic tests and genotypic methods such as ARDRA, rep-PCR and RAPD-PCR, as well as 16S rRNA gene sequencing of representative strains. Thus, the majority (...
Traditional fermentation of cassava is dominated by a lactic acid bacteria (LAB) population. Fermentation is important for improving product flavour and aroma as well as safety, especially by reduction of its toxic cyanogenic glucosides. The production of Gari from cassava in Benin typically occurs on a household or small industrial scale, and consequently suffers from inconsistent product qual...
Normal-gravity (22 to 24 degrees Plato) wheat mashes were inoculated with five industrially important strains of lactobacilli at approximately 10(5), approximately 10(6), approximately 10(7), approximately 10(8), and approximately 10(9) CFU/ml in order to study the effects of the lactobacilli on yeast growth and ethanol productivity. Lactobacillus plantarum, Lactobacillus paracasei, Lactobacill...
The aim of our study was to develop an original probiotic cheese based on the Estonian open-texture, smear-ripened, semisoft cheese "Pikantne." Cheese was produced by two methods using cheese starter cultures (Probat 505) in combination with 0.04% of probiotic Lactobacillus fermentum strain ME-3 (10(9) cfu/mL) with high antimicrobial activity and antioxidative properties. The probiotic Lactobac...
Food and feedstuff contamination with aflatoxins (AFTs) is a serious health problem for humans and animals, especially in developing countries. The present study evaluated antifungal activities of two lactic acid bacteria (LAB) against growth and aflatoxin production of toxigenic Aspergillus parasiticus. The mycelial growth inhibition rate of A. parasiticus PTCC 5286 was investigated in the pre...
Here, the impact of an extract derived from green tea (Camellia sinensis) and fermentation with Lactobacilli fermentum strain OCS19 was explored with acute alcohol-induced liver damage. The study employed the HepG2 hepatic cell line and an in vivo murine model of liver damage. L. fermentum-fermented green tea extract (FGTE) was found to possess pronounced alcohol metabolizing enzyme activity. I...
Lactobacillus fermentum strain JDFM216, isolated from a Korean infant feces sample, possesses the ability to enhance the longevity and immune response of a Caenorhabditis elegans host. To explore the characteristics of strain JDFM216 at the genetic level, we performed whole-genome sequencing using the PacBio system. The circular draft genome has a total length of 2,076,427 bp and a total of 2,6...
In this study, Limosilactobacillus fermentum PTCC 1638 and Lacticaseibacillus rhamnosus 1637 were used alone in combination to ferment quinoa seeds, the effect of fermentation (37 °C; 24 h) on pH, total phenols, tocopherols, vitamin C, antioxidant activity, enzymes inhibition (α-amylase α-glucosidase; antidiabetic effect) was investigated. The results showed that with increase time, bacterial p...
Background: Lipase enzymes are of great importance in various industries. Currently, extensive efforts have been focused on exploring new lipase producer microorganism as well as genetic and protein engineering of available lipases to improve their functional features. Methods: For screening lipase-producing lactobacilli, isolated strains were inoculated onto tributyrin agar plates. Molecular ...
