Bioactive Levan-Type Exopolysaccharide Produced by ZMR7: Characterization and Optimization for Enhanced Production.

Levan is an industrially important, functional biopolymer with considerable applications in the food and pharmaceutical fields owing to its safety and biocompatibility. Here, levan-type exopolysaccharide produced by Pantoea agglomerans ZMR7 was purified by cold ethanol precipitation and characterized using TLC, FTIR, H, and C NMR spectroscopy. The maximum production of levan (28.
