“…Among the microbial products, the surface‐active components and the enzyme lipase play a major role as the number of literatures suggested the condensation and the polymerization reactions and the intramolecular network are effective in the presence of enzyme and surface‐active agents. Markevich et al detailed the role of surfactant in increasing the adhesive nature of the product, where they used synthetic surfactants.…”

This study emphasizes microbial mediated transformation of sunflower oil to an adhesive product and characterization in detail. Marine bacterial isolates Bacillus (MTCC 5514), when grown in mineral medium, releases both hydrolytic enzymes and surface‐active components during the log phase of growth. When this species was grown in the presence of sunflower oil at an optimized concentration of 5% (w/v) under room temperature, enzymatic hydrolysis of oil proceeds with the release of fatty acids and glycerol. Further, on increasing the incubation period, the presence of surface‐active components, lipase and glycerol, influence the dimerization of the fatty acids, which further, transformed to a polymerized product sunflower oil‐based adhesive product with adhesive nature. Liquid chromatography‐mass spectrometry (electrospray ionization) analysis further authenticates the presence of dimeracids. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40555.

“…The increased adhesive nature observed in the product of the present study might be due to the biosurfactants available in the broth during the formation of the adhesive product and its involvement in the intramolecular network of the product. Markevich et al, (1986) detailed the role of surfactant in increasing the adhesive nature of the product, where, they employed synthetic surfactants. The thread like structures formed during the growth of the organism has been considered as the dimers of fatty acids or triglycerides polymers and these dimers are the precursors for the product formation, however, we couldn't ascertain the nature of dimers formed.…”
