ANTI-MICROBIAL AND ANTI ADHESIVE PROPERTIES OF LACTOBACILLUS AND BACILLUS SP.
AbstractThe aim of this study was to determine the anti-microbial and anti-adhesive properties of a Lactobacillus and Bacillus, against several micro-organisms, including Gram-positive and Gram-negative bacteria. Biofilm producing micro- organisms were isolated from different samples. The isolated micro-organism were characterized and identified. The anti-microbial and anti-adhesive activities were determined. The bacteroicin production was quantified and was observed. The maximum bacteroicin production was observed among various isolated micoorganisms. The bacteroicin produced by the Lactobacilli and Bacilli showed antimicrobial activity against pathogenic micro-organisms (including Pseudomonas, Escherichia col, Staphylococcus, Aspergillus and Salmonella typhi), the minimum inhibitory concentration (MIC) were achieved for bacteroicins the most. The antagonistic characteristics of bacteriocin were studied by agar well diffusion method. Furthermore, the micro- organism showed anti-adhesive activity against most of the micro-organisms evaluated. Biofilm production was observed and quantified among various biofilm producing isolated micro- organisms.
