Gluconobacter in biosensors: applications of whole cells and enzymes isolated from Gluconobacter and Acetobacter to biosensor construction.

Bacteria belonging to the genus Acetobacter and Gluconobacter, and enzymes isolated from them, have been extensively used for biosensor construction in the last decade. Bacteria used as a biocatalyst are easy to prepare and use in amperometric biosensors. They contain multiple enzyme activities otherwise not available commercially. The range of compounds analyzable by Gluconobacter biosensors includes: mono- and poly-alcohols, multiple aldoses and ketoses, several disaccharides, triacylglycerols, and complex parameters like utilizable saccharides or biological O2 demand. Here, the recent trends in Gluconobacter biosensors and current practical applications are summarized.
