Originální abstrakt

Microbial surface active substances (biosurfactants) are amphiphilic compounds produced by numerous microorganisms. These bio-based molecules reveal a number of advantages over oil-based surfactants. Biosurfactants are not toxic and, moreover, are fully biodegradable. Moreover, they can also be obtained from renewable sources and operate within a wide range of pH, temperature or salinity. Therefore, they might be used in numerous applications including those requiring non-toxicity and biocompatibility. Apart from biosurfactant biosynthesis, many bacteria produce also polyhydroxyalkanoates (PHA)-microbial polyesters that are considered biodegradable and renewable alternatives to petrochemical polymers. It should be noted, that PHA is an intracellular product whereas biosurfactants are extracellular, so it would be interesting to produce both valuable metabolites in a single biotechnological process. Therefore, we have employed various methods to screen biosurfactants production in selected PHA producers and we have identified potential strains which could be employed for simultaneous production of PHA and biosurfactants.
