A serious problem for humans is the propensity of Candida albicans to adhere to various surfaces and its ability to form biofilms. Surfactants or biosurfactants can affect the cell surfaces of microorganisms and block their adhesion to different substrates. This study investigated adhesion of C. albicans strains differing in cell surface hydrophobicity(More)
Lipopeptide biosurfactants are surface active biomolecules that are produced by a variety of microorganisms. Microbial lipopeptides have gained the interest of microbiologists, chemists and biochemists for their high biodiversity as well as efficient action, low toxicity and good biodegradability in comparison to synthetic counterparts. In this report, we(More)
To investigate the ability of the proteases, subtilisin and α-chymotrypsin (aCT), to inhibit the adhesion of Candida albicans biofilm to a polypropylene surface. The proteases were immobilized on plasma-treated polypropylene by covalently linking them with either glutaraldehyde (GA) or N′-diisopropylcarbodiimide (DIC) and N-hydroxysuccinimide (NHS). The(More)
The rapid and accurate quantification of biosurfactants in biological samples is challenging. In contrast to the orcinol method for rhamnolipids, no simple biochemical method is available for the rapid quantification of lipopeptides. Various liquid chromatography (LC) methods are promising tools for relatively fast and exact quantification of lipopeptides.(More)
