The optimum conditions for Acetobacter immobilization were investigated. The results show that: 1) the maximum oxygen uptake rate (OURm) and cell release are related to alginate and cell concentration in the gel; 2) different alginate concentration does not affect cell viability, but long storage in CaCl2 reduces the number of living cells; 3) the double alginate gel layers had no influence on cell viability and on the OURm and prevented cell leakage from the gel matrix.

Abstract
The optimum conditions for Acetobacter immobilization were investigated. The results show that: 1) the maximum oxygen uptake rate (OURm) and cell release are related to alginate and cell concentration in the gel; 2) different alginate concentration does not affect cell viability, but long storage in CaCl2 reduces the number of living cells; 3) the double alginate gel layers had no influence on cell viability and on the OURm and prevented cell leakage from the gel matrix.
