A process for treating hydrocarbon-containing effluents that comprise isoalkanes to reduce the hydrocarbon concentration at least partly is described, characterized in that in the presence of a suitable substrate, a CIP-I-2126 bacterium is grown, and the hydrocarbons that are contained in the effluents are degraded by the biomass of said bacteria that is thus produced. Application for pollution control of water and soil contaminated by hydrocarbons and optionally by ethers that come from a gasoline, kerosene and/or gas oil fraction.

Process for bacterial treatment of hydrocarbon effluents that contain isoalkanes

A process for treating aqueous effluents that contain at least one ether, preferably ethyl tert-butyl ether (ETBE) and/or methyl tert-butyl ether (MTBE) and/or tert-amylmethylether (TAME) to reduce the concentration of said ether is described, characterized in that in the presence of a growth substrate, at least one bacterium that is selected from the group that is formed by,CIP I-1889 and,CIP I-2053 is grown in aerobic conditions, and the ether that is contained in the effluents is degraded in the presence of the substrate by the biomass of the bacteria that are thus produced.

A process for treating aqueous effluents that contain ethyl-tert-butyl ether (ETBE) to reduce the ETBE concentration is described, characterized in that in the presence of effluents, at least one bacterium that is selected from the group that is formed by Gordona terrae CIP I-1889 and Rhodococcus equi CIP I-2053 and in the presence of at least one bacterium that is selected from the group that is formed by Pseudomonas cepacia CIP 1-2052, Arthrobacter globiformis ATCC 53596, Bacillus coagulans ATCC 53595, Pseudomonas stutzerii ATCC 53602 and Mycobacterium vaccae JOB5 are grown to degrade essentially all of the ETBE. The concentration of ETBE in the effluent is equal to at most 1500 mg/L. Application for the water treatment industry.

A process for producing glucose dehydrogenase consists of cultivating a mutant strain (ATCC 39 118) of Bacillus megaterium in a culture medium and recovering the resultant glucose dehydrogenase. The latter can be used in the enzymatic production of L-carnitine consisting of subjecting 3-dehydrocarnitine to the simultaneous action of carnitine dehydrogenase, nicotinamide adenine dinucleotide and glucose and glucose dehydrogenase.
