CHARACTERIZATION AND IDENTIFICATION OF A NEW STRAIN OF ESTERASE-PRODUCING BACILLUS-THERMOGLUCOSIDASIUS EAEC FROM AN AERATED THERMOPHILIC SEWAGE-SLUDGE

Enzymes and especially esterases become increasingly important as tool s for the organic chemist. Searching for esterase-producing microorgan isms a thermophilic, rod-shaped, endospore-forming bacterium, code-nam ed ''EAEC'', was isolated from an aerated thermophilic sewage sludge b y enrichment on ethyl acetate as the sole carbon source. Phenotypic an d genotypic investigations and comparisons led to the conclusion that this isolate belongs to the species Bacillus thermoglucosidasius.
