This study aimed to isolate and identify Lactobacillus in the honey stomach of honeybee Apis dorsata. Samples of honeybee were collected from A. dorsata colonies in different bee trees and Lactobacillus bacteria isolated from honey stomachs. Ninety two isolates were Gram-stained and tested for catalase reaction. By using bacterial universal primers, the 16S rDNA gene from DNA of bacterial colon...

Single and mixed starter cultures of lactic acid bacteria (LAB): Weissella confusa MNC20, Lactobacillus plantarum MNC21, Lactococcus lactis MNC24 and Lactobacillus fermentum MNC34 and yeasts: Issatchenkia orientalis MNC20Y and Saccharomyces cerevisiae MNC21Y were used to produce Obushera, a fermented sorghum beverage. Microbial counts, pH, sugars, organic acids, and volatile compounds in starte...

Background and Objectives: Chemical synthesis and extraction of flavorings from natural sources include disadvantages. However, biotechnology is a preferred method for biosynthesis of flavorings. The objective of this study was to synthesize natural esters with fruity flavors in whey using lipase of Palatase in combination with ethanol fermentation. Materials and Methods: Lactobacillus ferment...

In the present work, five hundred and sixty-seven isolates of lactic acid bacteria were recovered from raw bee pollen grains. All isolates were screened for their antagonistic activity against both Gram-positive and Gram-negative pathogenic bacteria. Neutralized supernatants of 54 lactic acid bacteria (LAB) cultures from 216 active isolates inhibited the growth of indicator bacteria. They were ...

Two high protein wheat flour samples of Red Horse (RH) and Bake with Yen (BY) were examined for predominant Lactobacillus spp. in fermented liquid sourdough. The identification of Lactobacillus spp. was based on biochemical tests of catalase test, gas carbon dioxide production, arginine test, the ability to grow at temperature of 15°C and 45°C and carbohydrate fermentation using API50CH kit. Th...

The effect of inulin on the viability Lactobacillus fermentum strain 4-17 in probiotic ice cream and evaluation its microbial physicochemical properties

Background: Lead is known to be a highly toxic heavy metal which has a wide range of effect on human health. It has been proven that probiotics are able to bind heavy metals and remove them from the environment. In this study, the effect of Lactobacillus fermentum (L. fermentum) and its cytoplasmic extract were investigated on the hematological and body weight parameters in lead exposed rats. ...

The paper lays out the short scientific history and characteristics of the new probiotic Lactobacillus fermentum strain ME-3 DSM-14241, elaborated according to the regulations of WHO/FAO (2002). L. fermentum ME-3 is a unique strain of Lactobacillus species, having at the same time the antimicrobial and physiologically effective antioxidative properties and expressing health-promoting characteri...

Lactobacillus fermentum is found in fermented foods and thought to be harmless. In vivo and clinical studies indicate that some L. fermentum strains have beneficial properties, particularly for gastrointestinal health. However, L. fermentum AGR1487 decreases trans-epithelial electrical resistance (TEER), a measure of intestinal barrier integrity. The hypothesis was that L. fermentum AGR1487 dec...
