Obtención de xantano a partir de Xanthomonas campestris B-1459 en fermentadores con agitación mecánica / [Isolation of xanthan from Xanthomonas campesteris B-1459 in mechanically agitated fermentors]

ABSTRACT

Xanthan production from Xanthomonas campestris was studied by a mechanically shaken fermentor. Influence of glucose concentration, aeration of culture media, rheology of broths and pH control was evaluated. Different aeration conditions based on variation of stirring rates were assayed. Substrate concentration was determined according to the Miller method, and polymer production was performed by the Cadmus method. The higher xanthan levels (i.e. 2.3
