Xanthan is a natural polysaccharide that is biosynthesized by metabolic activity of Gramnegative bacteria from the genus Xanthomonas. Commercial production of xanthan is mainly performed as aerobic submerged batch cultivation of the reference strain X. campestris ATCC 13951 on a medium of appropriate composition and under optimal conditions. The success of xanthan production is largely influenced by the selection of producing strains, formulation of cultivation medium composition, and control and regulation of bioprocess parameters. The aim of this study was to examine xanthan production on medium containing crude glycerol from domestic biodiesel industry using reference strain Xanthomonas campestris ATCC 13951 and Xanthomonas strains locally isolated from different vegetable cultures. Xanthan was produced by submerged cultivation of examined producing strains at a laboratory level under aerobic conditions at 30°C and 150 rpm for 168 h. Bioprocess efficacy was estimated based on the xanthan concentration in media at the end of biosynthesis. According to the obtained results, xanthan production on crude-glycerol based medium was possible by all applied Xanthomonas strains. The highest potential for successful xanthan production has PL4 strain, while strain Xp 3-1 has the lowest ability to biosynthesize xanthan in applied experimental conditions.
