Background: Growth of Gluconacetobacterdiazotrophicuswith glucose as carbon an energy source has been extensively studied. However, there are no reports in the literature describing growth of G.diazotrophicusin cultures ...

Several levan hyperproducing mutants of Zymomonas mobilis strains were selected by mutagenesis with N-methyl-N-nitro-nitrosoguanidine and caffeine. Highest levan production (41 g 1-1) was obtained with a mutant strain HL ...

The levan is a biopolymer of great importance to the food industry since it is capable of defining and modifying the structure of one food, acting as stabilizer, thickener, gelling agent and being largely responsible for ...

Levan is a polymer composed of fructose units linked by β(2→6) glycosidic bonds. It can be found in many plants and microbial products, and it has many applications in different industrial fields, such as foods and ...
