G. Spassov et al., CONVERSION OF D-SORBIT TO L-SORBOSE BY CELLS OF ACETOBACTER SUBOXYDANS IMMOBILIZED IN SINTERED GLASS, Applied microbiology and biotechnology, 43(1), 1995, pp. 35-37
A simple method for immobilizing cells of Acetobacter suboxydans by ad
sorption on inorganic sintered glass carriers is described. The immobi
lized cell preparations exhibited 100% of the initial activity when co
nverting D-sorbit to L-sorbose. This sintered glass was used in a fixe
d-bed loop reactor with a working volume of 0.21 for semicontinuous an
d continuous experiments. A prolonged working life span was achieved,
which could possibly satisfy requirements for scaled-up operations.
