This study was aimed at the isolation and identification of Lactic Acid Bacteria (LAB) from fermented drinks assaying for invertase enzyme produced by bacteria. Fresh samples were collected different sellers locations in Ile-Ife lactic acid bacteria isolated using De Man Rogosa Sharpe (MRS) agar determination microbial count. Standard morphological biochemical tests carried out characterization...

OBJECTIVE Probiotic Lactobacillus brevisCD2 (CD2) exerts anti-inflammatory properties by preventing nitric oxide synthesis. It is hypothesized that oral application of CD2 can inhibit naturally occurring gingival inflammation. MATERIALS AND METHODS Thirty-four healthy adults were randomized to receive L. brevisCD2 lozenges or placebo, three times daily for 14 days. The subjects refrained from...

The aim of the present study was to assess the microecosystem development and the dynamics of the lactic acid bacteria population during spontaneous fermentation of radish (Raphanus sativus L.) roots in brine at 20 and 30 °C. In both temperatures, lactic acid bacteria prevailed the fermentation; as a result, the pH value was reduced to ca. 3.6 and total titrable acidity increased to ca. 0.4% la...

A differential plating medium was developed to detect decarboxylating lactobacilli in cheese. With this medium, 15 cheeses made from raw milk were investigated for the presence of these bacteria. Five histidine-decarboxylating strains and one tyrosine-decarboxylating strain were isolated. The isolates were identified with the API 50L system. Accordingly, each of the five histidine-decarboxylati...

The effects of various compounds on the aerobic stability of silages were evaluated. It has been observed that inoculation of whole-crop maize with homofermentative lactic acid bacteria leads to silages which have low stability against aerobic deterioration, while inoculation with heterofermentative lactic acid bacteria, such as Lactobacillus brevis or Lactobacillus buchneri, increases stabilit...

OBJECTIVES To analyze the anti-inflammatory effects of Lactobacillus brevis extracts on periodontitis patients and to investigate the involved mechanisms in vitro on activated macrophages. METHODS Eight healthy subjects and 21 patients with chronic periodontitis were enrolled to analyze the effect of L. brevis-containing lozenges on periodontitis-associated symptoms and signs. Before and afte...

Certain strains of Clostridium butyricum exhibit characteristics probiotics that are now sold in eastern Asian countries such as Korea and Japan. Integral improvement C. functions can be achieved the presence Lactobacillus spp. through process attentive selection. This study aimed to select specific lactic acid bacteria could synergistically enhance probiotic butyricum. The supernatants 249 wer...

Two new surface layer (S-layer) proteins (SlpB and SlpD) were characterized, and three slp genes (slpB, slpC, and slpD) were isolated, sequenced, and studied for their expression in Lactobacillus brevis neotype strain ATCC 14869. Under different growth conditions, L. brevis strain 14869 was found to form two colony types, smooth (S) and rough (R), and to express the S-layer proteins differently...

1 2 A Central Composite Face design was used to study growth and tyramine production 3 by two strains of lactic acid bacteria, Lactobacillus brevis CECT 4669 and Enterococcus 4 faecium BIFI-58. The effects of five physicochemical factors (incubation temperature and 5 time, environmental pH, added tyrosine concentration, and pyridoxal-5-phosphate (PLP) 6 supplementation) on cell growth and tyram...
