Its optimal formation is dependent on the presence of an inducer (sucrose) and an organic nitrogen source. High nitrogen concentrations increase growth rate and sucrose hydrolysis and significantly decrease levansucrase formation. The pH activity curve of the levansucrase studied is asymmetric and the optimal pH value for its activity is 7ยท0. These findings suggest that this levansucrase differs from other levansucrases so far described. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-15-3-462
