Fructooligosaccharides (FOS) and levan attract much attention due to a wide range of
applications in food technology and pharmaceutical and cosmetic industry. Bacillus …

A newly isolated thermophilic bacterial strain from Tunisian thermal source was identified as
Bacillus sp. and was selected for its ability to produce extracellular levansucrase. Following …

The production of levansucrase (LS) by thermophilic Geobacillus stearothermophilus was
investigated. LS production was more effective in the presence of sucrose (1%, w/v) than …

Bacillus circulans was able to produce extracellular levansucrase using sucrose as carbon
source optimally at 35° C. The enzymic synthesis of levan and fructo-oligosaccharides was …

Fructooligosaccharides and levan have a wide range of applications in the food industry due
to their physiological and functional properties. The enzymatic synthesis of these molecules …

Levansucrase is a microbial enzyme, classified as fructosyltransferase and responsible for
levan polymerization. Levan is a polyfructan widely used in pharmaceutical, industrial and …

The rising global population continues to threaten the world's food security. The discovery of
new technologies to produce food of nutritional and functional properties is urgently needed …

This article investigates the production and optimization of levansucrase using synthetic
medium by Zymomonas mobilis NRRL B‐14023. Response surface methodology was used …

Levan has attracted interest due to the potential health benefits associated with its prebiotic,
biological, and functional properties. However, the production of levan is expensive due to …

Levan is a fructan whose backbone is composed of β-(2-6) linkages. It is synthetized by the
enzyme levansucrase (EC 2.4. 1.10). The effect of Fe 3+, K+, Mg 2+, Mn 2+, and Zn 2+ in the …
