ABSTRACT
The purpose of this investigation was to study the effect of Xanthomonas campestris cells immobilized in
various matrices, such as calcium alginate, k-Carrageenan and ployacrylamide, for the production of
xanthan. Calcium alginate was found to be an effective and suitable matrix for higher xanthan
productivity compared to the other matrices studied. Calcium alginate matrix was selected for repeated
batch fermentation. The average specific volumetric productivity with calcium alginate was 69g/l, which
was the higher production over the conventional free-cell fermentation. In the repeated batch
fermentations of the shake flasks, an optimum level of xanthan production was maintained for 4 days
using calcium alginate immobilized cells. From the results, it is concluded that the alginate immobilized
cells of X. campestris can be proposed as an effective biocatalyst for repeated usage for maximum
production of xanthan.
Keywords: Xanthan production, X. campestris, immobilized cells, repeated batch fermentation.
