3. Maldi-tof mass spectrometry for the identification and detection of antimicrobial activity of lactic acid bacteria isolated from local cheeses
Abstract In this study, 21 traditionally made cheeses were used. A total of 150 lactic acid bacteria (LAB) isolates were obtained from cheeses. 100 of them were identified at genus levels as Leunoconostoc (10), Lactobacillus (46) and Enterococcus (44) using biochemical tests. 71 strains were identified as Enterococcus durans (6), E. faecalis (18), E. faeciu

4. Importance of the agar-media in the evaluation of bacteriocin activity against the same test-microorganisms
Abstract Bacteriocins are peptides produced by various species of bacteria, especially lactic acid bacteria, which exhibit a large spectrum of action against spoilage bacteria and foodborne pathogens. Successful application of techniques for quantitative or qualitative bacteriocin determination relies not only on the sensitivity of the test-microorganisms, b

5. An Insight Into the Intraspecific Variation of Biosynthetic Gene Clusters Between Strains of Burkholderia thailandensis spp.
The present study aimed to investigate the intraspecific variation of biosynthetic gene clusters (BGCs) in different strains of Burkholderia thailandensis in order to guide natural products (NPs) discovery process. Species from the genus Burkholderia are emerging as promising species due to their biosynthetic potential. Through genome-mining strategies, it w

6. Production and Characterization of Bacteriocin Produced by Lactobacillus Viridescence(NICM 2167)
The present study focused on the production optimization of bacteriocin by Lactobacillus viridescence NICM 2167 followed by its purification and characterization. The bacteriocins are antimicrobial peptides produced by many Gram positive and Gram negative bacteria.The bacteriocin produced by LAB (lactic acid bacteria) received attention in recent years due t

7. Biophysicochemical characterization of Pyocin SA189 produced by Pseudomonas aeruginosa SA189
Abstract Pseudomonas aeruginosa, in spite of being a ubiquitous organism (as it is found in soil, water, and humans), is also an opportunistic pathogen. In order to maintain its diversity in the community, it produces various toxic proteins, known as, bacteriocins. In the present study, pyocin SA189, which is a bacteriocin produced by P. aeruginosa SA189 (is

9. Bacteriocinogenic Lactococcus lactis subsp. lactis DF04Mi isolated from goat milk: characterization of the bacteriocin
Lactic acid bacteria capable of producing bacteriocins and presenting probiotic potential open innovative technological applications in the dairy industry. In this study, a bacteriocinogenic strain (Lactococcus lactis subsp. lactis DF4Mi) was isolated from goat milk, and studied for its antimicrobial activity. The bacteriocin presented a broad spectrum of ac

11. Optimization of nutritional and non-nutritional factors involved for production of antimicrobial compounds from Lactobacillus pentosus SJ65 using response surface methodology
Bacteriocins from lactic acid bacteria are ribosomal synthesized antibacterial proteins/ peptides having wide range of applications. Lactobacillus pentosus SJ65, isolated from fermented Uttapam batter (used to prepare south Indian pan cake), produces bacteriocin having a broad spectrum of activity against pathogens. Optimization studies are of utmost importa

12. Antagonistic activity expressed by Shigella sonnei: identification of a putative new bacteriocin
Bacteriocins are antibacterial, proteinaceous substances that mediate microbial dynamics. Bacteriocin production is a highly disseminated property among all major lineages of bacteria, including Shigella. In this paper, we addressed the purification and characterisation of a bacteriocin produced by a Shigella sonnei strain (SS9) isolated from a child with ac
