1.6.1 Anti-adhesive properties Biofilms are of great attention in many industries such as medical and food because bacteria colonize medical devices and food processing surfaces by changing their properties (Zeraik and Nitschke, 2010). One of the very important applications of bio-surfactants is their role as anti-adhesive agents to pathogens, making them useful for treating many diseases and as therapeutic and probiotic agents. Bio-surfactants not only prevent adhesion of bacteria to the surfaces, but also induce detachment of already adherent cells. Involvement of bio-surfactants in microbial adhesion and desorption has been widely described, and constitutes an effective strategy to reduce microbial adhesion and combat colonization by pathogenic microorganisms, not only in the biomedical field, but also in other areas, such as the food industry. The bio-surfactant produced by various species of genus Lactobacillus (L. paracasei, L. plantarum, L. delbrueckii, L. acidophilus, L. casei, L. fermentum, L. rhamnosus L. spp., L. reuteri, L. brevis) was screened for their anti-adhesive properties. The highest anti-adhesive activity was recorded for L. fermentum bio-surfactant against Candida albicans 22 CBS 5703 (84.69%). On the other hand, the lowest activity was recorded for L. delbrueckii bio-surfactant against…show more content…
This approach reduces the cost for wastewater treatment with even a potential of generating a profit through the sale of the biosurfactant (Kosaric, 1992). In bioremediation processes, cost effective, contaminant specific treatment are done to reduce the concentration of individual or mixed environmental contaminants. The process of bioremediation can be done by utilizing plants, microbes or microbial
