Original Abstract

Bacterial cellulose is an extracellular polysaccharide produced by many bacterial strains as a protective envelope against the environment. It possesses unique mechanical and physical properties that enable a wide range of applications in medicine, cosmetics, electronics, textile and food industry or biotechnology. However, the main disadvantage of bacterial cellulose is its high production costs1. Food- and agricultural-based industries produce a vast quantity of waste with high sugar content or hemicellulose/cellulose that may be transformed into a carbon source for bacterial cultivation. About one third of all food produced globally is wasted annually2. This work is focused on the utilization of carbon sources present in grape pomace, banana peels or by-products arising during the isolation of lignin. The carbon sources were derived via hydrolysis of the waste mentioned above and the hydrolysates were used directly in media to cultivate Komagataeibacter xylinus. The tested hydrolysates have been proven to be suitable carbon sources for cultivating K. xylinus. The yields of bacterial cellulose produced on modified media were found to be higher compared to standard media. Morphological and rheological properties of modified bacterial cellulose were investigated to find out possible differences to the standard cultivation technique.
