“…Despite promising results in displacing adhering uropathogens and inhibiting bacterial adhesion to catheter materials [40][41][42][43][44][45][46][47][48], the application of probiotics as a coating for UTDs remains barely explored. Since bacterial adhesion and biofilm growth are affected by the hydrodynamic forces around surfaces [49], and these forces vary between the upper and lower urinary tract, as well as on the inner and outer part of the device, it is important to consider this variability when setting an experimental assay of biofilm formation [9].…”

Novel technologies to prevent biofilm formation on urinary tract devices (UTDs) are continually being developed, with the ultimate purpose of reducing the incidence of urinary infections. Probiotics have been described as having the ability to displace adhering uropathogens and inhibit microbial adhesion to UTD materials. This work aimed to evaluate the effect of pre-established Lactobacillus plantarum biofilms on the adhesion of Escherichia coli to medical-grade silicone. The optimal growth conditions of lactobacilli biofilms on silicone were first assessed in 12-well plates. Then, biofilms of L. plantarum were placed in contact with E. coli suspensions for up to 24 h under quasi-static conditions. Biofilm monitoring was performed by determining the number of culturable cells and by confocal laser scanning microscopy (CLSM). Results showed significant reductions of 76%, 77% and 99% in E. coli culturability after exposure to L. plantarum biofilms for 3, 6 and 12 h, respectively, corroborating the CLSM analysis. The interactions between microbial cell surfaces and the silicone surface with and without L. plantarum biofilms were also characterized using contact angle measurements, where E. coli was shown to be thermodynamically less prone to adhere to L. plantarum biofilms than to silicone. Thus, this study suggests the use of probiotic cells as potential antibiofilm agents for urinary tract applications.

“…As a result, the combination of factors listed above leads to the resistance of pathogenic microorganisms to antibiotics, which causes necessity of the development of new effective antimicrobial drugs. One of the modern trends in the search for medicines with antimicrobial activity is the use of bacteriocins [1,42]. Bacteriocins are ribosomally synthesized peptides or proteins produced by bacteria.…”

“…Bacteriocins are synthesized by various microorganisms and have already found wide application in medicine, veterinary medicine and food technologies as a therapeutic agent, as well as a food preservative to combat various infectious and food pathogens. Some antibiotics have harmful side effects on human health whereas bacteriocins do not have any or have little cytotoxicity [1,9,17]. It is mainly because the tested bacteriocins were produced by the lactic acid bacteria.…”

The review presents the characteristics of bacteria of the Lactobacillus family and their abi lity to synthesize various bacteriocins. The classification of bacteriocins of lactobacilli is given, which includes three classes: class I -lantibiotics (peptides with a molecular weight of less than 5 kDa, which contain lanthionine), class II -unmodified bacteriocins, also called nonlantibiotics (heat-resistant peptides , which do not contain lanthionine and have a molecular weight less than 10 kDa), and class III -a poorly studied group of thermolabile proteins with a molecular weight of more than 30 kDa. Lactobacilli are shown to synthesize a wide spectrum of bacteriocins, which demonstrate a variety of actions and are able to inhibit the growth of numerous species of opportunistic gram-positive microflora. The article also provides the examples of bacteriocins produced by Lactobacillus isolated from food products (fermented meat, fish, kombucha, goat milk, koumiss, etc.) and various human biotopes (microbiota of breast milk, intestinal tract and vaginal secretions). Additionally, the review shows the prospects of wide application of bacteriocins synthesized by Lactobacillus in the food and pharmaceutical industries.

Abstract. Retnaningrum E, Yossi T, Nur'azizah R, Sapalina F, Kulla PDK. 2020. Characterization of a bacteriocin as biopreservative synthesized by indigenous lactic acid bacteria from dadih soya traditional product used in West Sumatra, Indonesia. Biodiversitas 21: 4192-4198. A total of 4 isolates of lactic acid bacteria (strain BDL08, BDL11, BDL12, and BDL13) isolated from dadih soya were investigated for the ability to produce bacteriocin based on their antibacterial activities against Listeria monocytogenes ATCC 7644. Based on comparative 16S rDNA sequencing analysis, isolates BDL 11, BDL12, and BDL13 were identified as Lactobacillus plantarum while the isolates BDL 08 was identified as Leuconostoc mesenteroides. All crude bacteriocins producing strains revealed broad antibacterial spectrum against 7 different indicator bacteria, including Gram-positive and Gram-negative bacteria. L. plantarum BDL11 displayed the highest bacteriocin activity relative to others. The bacteriocin produced by the strain was not affected by pH, heating, and NaCl concentration but was sensitive to proteolytic enzymes. This research indicated that the bacteriocin in the food industry has the potential to be used as a biopreservative.
