Evaluation of Lactobacillus strains for the production of proteinaceous antimicrobial substances

Popis výsledku v původním jazyce

Lactobacillus strains have been widely used in food industry for centuries and are considered to be GRAS (generaly recognized as safe) organisms. The antimicrobial substances produced by Lactobacillus strains have received most considerable attention inrecent years. Inhibitory role may play antimicrobial compounds such as different organic acids, hydrogen peroxide, carbon dioxide or proteinaceous substances (e.g. bacteriocins). The aim of the work was screening of Lactobacillus strains isolated from breastfed full-term infant faeces for production of proteinaceous antimicrobial substances using agar-spot test and agar-diffusion test. All lactobacilli produced different antimicrobial substances such as acids, hydrogen peroxide or proteinaceous substances inhibiting the growth of indicator strains. The inhibition was strain-specific and was dependent on tested strain and also on indicator strain. Tested lactobacilli were the most effective against lactobacilli indicator strains. Lactoba
