“…[ 23 ] mentioned that abundant of researches involved the remarkable ability of Lactobacilli in inhibiting pathogens growth through its bactericidal activity (such as production of bacteriocins, hydrogen peroxide and lactic acid as a byproduct of metabolism) and allow the body's immune system to overcome the infection without the use of antimicrobials. Ramos et al [ 23 ] stated that lactobacilli supernatants diminished the quorum signals (acyl-homoserine-lactones) produced by P. aeruginosa . Given that these signals are necessary for biofilm formation, hence, such diminishing of signals may cause an interruption in biofilm formation.…”

Context:Pseudomonas aeruginosa is a gram negative opportunistic bacteria causes several infections commonly colonize these devices and developing biofilms. Bacteria in biofilm can be up to 1,000 times more resistant to antibiotics than the same bacteria circulating in a planktonic state.Case Report:A total of 10 isolates of Pseudomonas aeruginosa were isolated from catheter associated urinary tract infections. While carbenicillin was the most effective antibiotic, all isolates developed multidrug resistant. Both crude and purified bacteriocin showed marked inhibition activity against planktonic and biofilm of the highly resistant isolate P. aeruginosa P7.Conclusion:Bacteriocin extracted from a locally isolated L. acidophilus has an anti P. aeruginosa biofilm activity also it can be used as a therapeutic agent after adequate in vivo experimentation.

“…Westbroek et al (2010) Steptococcus cells were mixed before plating. It appears therefore that the inhibitory action requires pre-application of the Lactobacillus or its products to the surface before exposure to the biofilm-forming organism, as was demonstrated in the study by Fracchia et al (2010).…”

Bacterial biofilms forming on indwelling urinary catheters continue to represent a public health problem because they are associated with urinary tract infections (UTIs). This study was undertaken to evaluate the ability of immobilized Lactobacillus acidophilus cells to inhibit biofilm formation on catheter surfaces. Urine bacteria and Lactobacillus species were isolated from urine and vaginal swabs (HVS), respectively. Immobilization of L. acidophilus on catheter samples was achieved using sodium alginate and the inhibition of urine bacteria by the immobilized Lactobacillus cells was evaluated by microscopy and viable cell count procedures following co-culture of the immobilized cells and urine bacteria. Results showed that pre-coating of catheter surfaces with L. acidophilus before exposure to urine bacteria significantly (p<0.05) reduced attachment of some urine bacteria to the catheter surfaces. Staphylococcus aureus, Klebsiella and Escherichia coli were significantly inhibited, while Pseudomonas aeruginosa was not inhibited. Furthermore, crude bacteriocin preparations from the Lactobacillus cells had antimicrobial activity against the urine bacteria. This study shows that precoating of catheter surfaces with L. acidophilus could be an effective strategy for controlling biofilm formation on urinary catheters.

“…Lactobacillus species have long been recognized to exist in the vaginal canal of humans and serve a significant and perform essential role in maintaining and improving health by limiting the proliferation of harmful organisms by creating various defensive mechanisms [19]. Lactobacillus can provide these important health benefits to the individual by producing lactic acid, bacteriocins, and hydrogen peroxide, all of which limit the growth of bacteria, being harmful or not and fungal pathogens that cause urogenital tract infections [20]. This argument of Lactobacillus being present in a female's vagina canal to improve health agrees with the fact that Döderlein isolated Döderlein's Action mechanism of vaginal lactobacillus species [17].…”

Lactic acid bacteria are gram-positive microorganisms that are characterized by the production of lactic acid as a key fermentation product. LAB, specifically Lactobacillus delbrueckii subsp. bulgaricus, are essential dairy starter cultures for the manufacture of several fermented dairy products such as yogurt. Some LAB are useful microorganisms and are well known to have probiotic effects to provide foods with unique sensory qualities such as aroma and taste. Probiotic strains help to strengthen the human immune system, increasing the body’s resistance to diseases. Additionally, probiotics and postbiotics improve gut microbiome balance and prevent health issues. Postbiotics are substances that are produced by microbes’ metabolic activities and have a positive impact on diseases, either directly or indirectly. Extensive research has shown that postbiotics possess immunomodulatory and significant clinical effects. Their use has been found to enhance general health and alleviate symptoms of various disorders in healthy individuals. Furthermore, postbiotics exhibit anti-inflammatory, antioxidant, and anticancer properties. Therefore, this chapter presents an overview and the importance of LAB as a probiotic and its importance to human health, metabolic fermentation, and antioxidant potential. The review also discusses different biotechnological methods that improve the survival rate of probiotics during processing and GIT transit like microbial encapsulation.
