Characterization of thermostable β-amylase isozymes from Lactobacillus fermentum

International Journal of Biological Macromolecules, 2016
A strain of Lactobacillus fermentum producing two isozymes of a 20kDa β-amylase was isolated from the faecal sample of a newborn. The starin was identified by sequencing its 16S rRNA gene. The two β-amylase isozymes were resolved and visualized by two dimensional protein gel electrophoresis (2-D gel electrophoresis).

Purification of α-galactosidase from Lactobacillus fermentum

Journal of Biotechnology, 1996
Abstract The purification and properties of α-galactosidase from Lactobacillus fermentum are described. This enzyme has different characteristics from those isolated from other microorganisms. Its molecular mass is 194500 Da and it is composed of four subunits of 45 kDa each.

Identification of Antimicrobial Peptides from Novel Lactobacillus fermentum Strain

The Protein Journal, 2020
Antimicrobial peptides (AMPs) are natural antagonistic tools of many bacteria and are considered as attractive antimicrobial agents for the treatment of bacteria with multidrug resistance. Lactic acid bacteria from the gastrointestinal tract of animals and human produce various AMPs inhibiting the growth of pathogens.

Regulation divergences of Lactobacillus fermentum PCC and Lactobacillus paracasei 431 on penicillin-induced upper respiratory tract microbial dysbiosis in BALB/c mice.

Food & Function, 2021
Antibiotic-induced host health imbalance during upper respiratory tract infection (URTI) treatment is an emerging issue. Studies have confirmed that Lactobacillus casei 431 and Lactobacillus fermentum PCC alleviate gut microbiome dysbiosis and improve ...

Complete glutathione system in probiotic Lactobacillus fermentum ME-3

Applied Biochemistry and Microbiology, 2010
There is much information about glutathione (GSH) in eukaryotic cells, but relatively little is known about GSH in prokaryotes. Without GSH and glutathione redox cycle lactic acid bacteria (LAB) cannot protect themselves against reactive oxygen species. Previously we have shown the presence of GSH in Lactobacillus fermentum ME-3 (DSM14241).

Purification and characterization of acid urease from Lactobacillus fermentum

Applied Microbiology and Biotechnology, 1990
Acid urease was purified to an electrophoretically homogeneous state, and the molecular weight was estimated to be 220,000. The enzyme consisted of three kinds of subunits, designated alpha, beta and gamma, with molecular weights of 67,000, 16,800 and 8600, respectively, in a (alpha 1 beta 2 gamma 1)2 structure.

Characteristics of yeast cell flocculation by Lactobacillus fermentum

Journal of Fermentation and Bioengineering, 1993
Abstract The effects of different metal ions, carbohydrates, heat and enzymatic treatments on the flocculation of yeast cells caused by a flocculant type of Lactobacillus fermentum were investigated. Calcium ion was required at pH 3.0, 4.5 and 6.2 for complete flocculation.
