Acetylated Carbohydrate Derivatives as C-Sources for Acetobacter xylinum

Abstract
Fully acetylated carbohydrate derivatives were used as C-sources instead of glucose for cultivation of Acetobacter xylinum. The resulting bacterial celluloses were analysed by IR-spectroscopy for possible incorporation of these substrates into the (1→4)-β-glucan chains. It is established, that acetyl substituents found in the polymer product are due to acetylated derivatives which are associated or intercalated with the produced bacterial cellulose.
