cannot be used in the production of animal feed due to their
high fiber count, resulting in considerable environmental
problems when they are discarded without treatment [15].
The use of alternative substrates such as shrimp shell to pro-
duce xanthan gum eliminates the environmental problems of
waste disposal producing a biopolymer with high added value
at low cost.
This study is innovative in providing specific information
to support the design of an aerobic batch bioreactor to
produce xanthan gum by fermenting shrimp shell. This
paper compares the yields and viscosities of the xanthan
gums produced from shrimp shell by three native strains
of Xanthomonas campestris with those obtained from the
fermentation of sucrose.
