The biosensor was used to determine BOD in lake
water and municipal wastewaters; its lifetime was more than 40
days. In [8–9], microorganisms Bacillus licheniformis, Dietzia maris
and Marinobacter marinus isolated from sea water were used. The
biosensor described was capable of stable operation for up to 10
months and was successfully used to assay sea water samples.
Despite the available descriptions of BOD biosensors based on
microbial co-cultures, the predominant number of studies have
