چکیده

According to World Health Organization, antibiotic resistance is rising dangerously high levels in all parts of the world. New mechanisms are emerging and spreading globally, threatening our ability treat common infectious diseases. Therefore, searching for new antimicrobial agents natural origin an extraordinary global problem. The work aimed determine activity lyophilized enzymatic lysate cells Lactobacillus rhamnosus V strain lactic acid bacteria. object study was drug Del-Imun V®, which hasanti-allergican dimmuno stimulating activity. researchers' efforts fully reveal drug's potential, particularlyitsanti microbialaction. Antimicrobial determined by minimum inhibitory concentration (MIC). Determination MIC carried out method twotime serial dilutions meat-peptone broth (MPB) bacteria liquid wort yeast. Gram-negative (Escherichia coli IEM-1, Proteus vulgaris PA-12, Pseudomonas sp. MI-2) Gram-positive (Bacillus subtilis BТ-2, Staphylococcus aureus BМС-1) bacteria, as well yeast (Candida albicans D-6, Candida tropicalis PE-2, utilis BVS-65). It shown that valuesof native preparation bacterial test cultures (EscherichiacoliIEM-1, Bacillussubtilis BT-2, Staphylococcusaureus BMS-1, Proteusvulgaris Pseudomonassp. were 8 time slower, than those thermally activated preparation, forthe yeasts (Candidaalbicans Candidatropicalis Candidautilis BVS-65) – 4-8 slower. As a result conducted research, antibacterial antifungal drugDel-Imun V® established. spectrum concerned gram-positiveand gram-negative yeast-like fungi genus Candida. concentrations quite low: from 1.0 4.0 μg/ml 62.5 125 culture B. BT-2 least sensitive action (MIC 12.5 μg/ml). There fore, it can be concluded lacticacid bacteriahasanti landanti fungal properties.

Phenyllactic Acid: A Potential Antimicrobial Compound in Lactic acid Bacteria

3-Phenyllactic acid (PhLA) is a broad spectrum antimicrobial compound active against bacteria and fungi. PhLA exists in two chiral isomers, L-PhLA and D-PhLA which show antimicrobial activity. D-PhLA shows more antimicrobial activity than L-PhLA and hence it is receiving great attention as food and feed additive in place antibiotics which control the microbial contamination and thereby increase...

L-Lactic Acid Production by Lactobacillus rhamnosus ATCC 10863

Lactic acid has been shown to have the most promising application in biomaterials as poly(lactic acid). L. rhamnosus ATCC 10863 that produces L-lactic acid was used to perform the fermentation and molasses was used as substrate. A solution containing 27.6 g/L of sucrose (main composition of molasses) and 3.0 g/L of yeast extract was prepared, considering the final volume of 3,571 mL (14.0% (v/v...

Antimicrobial microbes-bacteriocin producing lactic acid bacteria

The contribution of lactic acid bacteria (LAB) to the improvement of food safety and stability of fermented foods has long been known. LAB overgrow other microorganisms of the same ecological niche in food products mainly due to lowering the pH, competing for nutrients, producing various antimicrobial substances such as organic acids, hydrogen peroxide, antibiotics and bacteriocins. Among these...
