Exopolysaccharide production from Sclerotium glucanicum NRRL 3006 and Botryosphaeria rhodina DABAC-P82 on raw and hydrolysed starchy materials.
OBJECTIVE
Evaluation of fermentative usage of raw starchy materials for exopolysaccharide (EPS) production by Sclerotium glucanicum NRRL 3006 and Botryosphaeria rhodina DABAC-P82.


RESULTS
Non-hydrolysed corn starch, soft wheat flour, potato flour, cassava flour, sweet and industrial potato flours, and corn starch hydrolysed to different dextrose equivalent (DE) were tested in shaken culture for EPS production. Both fungal strains produced EPS on all tested materials but the production was maximum on hydrolysed corn starch (30.5 and 19.8 g l(-1) by B. rhodina and S. glucanicum on corn starch at 100 and 62 DE, respectively).


CONCLUSIONS
Raw starchy materials as such and, in particular, partially or totally hydrolysed corn starch could be used profitably for EPS production by S. glucanicum and B. rhodina.


CONCLUSIONS
The excellent EPS production, productivity and yield of B. rhodina DABAC-P82 when grown on 60 g l(-1) of totally hydrolysed corn starch.
