Bacterial cellulose synthesized by Gluconacetobacter hansenii for medical applications

Abstract

The properties of a polymer synthesized by the Gluconacetobacter hansenii strain GH-1/2008 were investigated. The studied bacterial cellulose polymer films are characterized by a mesh nanostructure composed of micro- and macrofibrils, a high water absorption capacity 556 ± 16.8%, and high strength and elasticity. Analysis of the spectrum recorded by ¹³С CP/MAS NMR spectroscopy showed that the bacterial cellulose synthesized by G. hansenii GH-1/2008 is a pure compound composed of Iα (65–70%) and Iβ (30–35%) allomorphs without any other impurities. It was found that the bacterial cellulose films with adsorbed antibiotics such as amoxiclav and fluconazole can be used as antibacterial and antifungal wound healing materials.
