Lactic acid bacteria

This study proceeded to address the following objectives: To evaluate the effect of gas composition commonly used in modified atmosphere packaging (80% O2 and 20% CO2) on the shelf life of beef patties; to formulate an optimal solution containing natural antioxidant and antimicrobial preservatives and to study the effect of this combination and MAP on physiochemical attributes (surface colour (chroma, hue angle), metmyoglobin and oxmyoglobin contents, lipid stability) of fresh beef patties; to evaluate the effect of combined antioxidant – antimicrobial natural preservative and MAP on packag...

Hai chủng vi khuẩn lên men lactic (LAB) Lactobacillus sp. L5 và Lactobacillus sp. C1 được phân lập từ nem chua và cơm mẻ thể hiện khả năng ức chế nấm mốc nhiễm bánh mì Aspergillus niger khi khảo sát in vitro. Hai chủng này được sử dụng đồng lên men với nấm men làm nổi bột nhằm kéo dài thời gian bảo quản và cải thiện chất lượng bánh mì.

The present researchaimed to investigate the morphological, biochemical and genotypic characterization of dominant lactic acid bacteria that were isolated from traditional dairy products in Iranian tribes . A total of 75 samples of traditional yogurt, doogh from dairy units in Fars province were randomly collected. Isolation of lactic acid bacteria, biochemical and genotypic identification were conducted. Totally, 157 LAB isolates were selected.

LAB have been isolated from fermented food, milks and plants, however, a few studies of LAB from soils have been reported. This study aimed to isolate, screen and identify LAB from vegetab le-growing soils collected from Da Lat (Lam Dong province). From 33 soil samples, 25 LAB isolates were selected on MRS agar supplemented with 1CaCO3.

Alternative strategies are needed in pest management to protect crops from pests. Occurrence of epiphytic lactic acid bacteria (LAB) on crop plants, especially on sites that are selected by pests, may be associated with host selection by insects. We carried out laboratory investigations as well as screen house and field experiments to understand whether epiphytic LAB occur at oviposition sites of agricultural and horticultural crops, probably modulating pest abundance by attraction or repulsion. The diversity of such epiphytic LAB associated with insect oviposition sites is discussed.

The experiment was conducted to determine the effects of L. plantarum, P. pentosaceus, and L. fermentum supplemented diet on survival, resistance to AHPND in white leg shrimp. The experimental results showed that the density of Vibrio spp. in the gut lumen of shrimp was significant decreased during the experimental period in the treatments of which the lactic acid bacteria (LAB) used as supplemented diet and without challenged with Vibrio parahaemolyticus.

Type IIa bacteriocins, which are isolated from lactic acid bacteria that are useful for food preservation, are potent antimicrobial peptides with considerable potential as therapeutic agents for gastrointestinal infections in mam-mals. They are ribosomally synthesized as precursors with an N-terminal leader, typically 18–24 amino acid residues in length, which is cleaved during export from the produ-cing cell.

Glucansucrases from lactic acid bacteria convert sucrose into variousa-glu-cans that differ greatly with respect to the glucosidic bonds present (e.g. dextran, mutan, alternan and reuteran). This study aimed to identify the structural features of the reuteransucrase from Lactobacillus reuteri121 (GTFA) that determine its reaction specificity.
