Resumo: | ABSTRACT Using the classic biotechnological methods, the dependence of A. vinelandii D-05 culture alginate production from the media carbon and nitrogen content was investigated. The maximal alginate production was observed during cultivation bacterium in the medium with 2 to 4% of sucrose, but the maximal growth was found in the medium with 4% glucose. It was found that for the alginate production the optimal nitrogen contents could take from 0.05% yeast extract (carbon: nitrogen ratio 168:1). For the first time we demonstrated possibility the A. vinelandii growth during the cultivation in a medium with molasses (a by-product of sugar production) and the significant polysaccharide production (16.6 g/l) was obtained. It was established, that A. vinelandii culture broth could be used as a biological binder for obtaining the biocomposite materials.
