ABSTRACT



The tested strain of Bacillus subtilis DSM 347 was employed in investigations determining the impact of temperature and saccharose concentrations on the in vivo yield of levan synthesis. The best results were obtained in the treatment at 15% saccharose supplementation at 37°C. The obtained levan was subjected to acid and enzymatic hydrolysis and the composition of hydrolysates was examined using the spectrophotometric and densitometric methods on TLC plates.

Key words: Bacillus subtilis, levan, levansucrase..
