Molecular parameters of bacterial cellulose.

Effect of temperature and pH biosynthesis medium

Polimery 2003, No 11-12, 779


DOI: dx.doi.org/10.14314/polimery.2003.779


Summary

The article presents the results of studies on the effect of temperature and pH of the culture medium on molecular properties (Mw and Mn values, polydyspersity, radius of gyration) and on the productivity of biosynthesis of bacterial cellulose using gram-negative bacteria Acetobacter xylinum. The results prove that the temperature of the process significantly affects the properties of the product. It was found out that the optimum temperature of biosynthesis is about 30 °C whereas the pH value of the culture medium ranging from 3.8 to 7.5 only slightly affects the properties of the obtained bacterial cellulose.


Keywords: bacterial cellulose parameters of biosynthesis, molecular characteristics, gel permeation chromatography
