Aerobic methylotrophic bacteria able to grow with dichloromethane (DCM) as the sole carbon and energy source possess a specific glutathione S-transferase, DCM dehalogenase, which transforms DCM to formaldehyde, used for biomass and energy production, and hydrochloric acid, which is excreted. Evidence is presented for chloride-specific responses for three(More)
A knockout mutant of Methylobacterium dichloromethanicum DM4 with an inactivated gene of a putative transcription regulator METDI5511 (ΔMETDI5511) has been obtained. The expression of this gene increases many times when the strain is grown on dichloromethane compared to methanol. The mutant had a low growth rate on dichloromethane as compared with the(More)
Activation of expression of the xoxF gene encoding PQQ-dependent methanol/ethanol dehydrogenase (METDI2492) in dichloromethane (DCM)-grown Methylobacterium dichloromethanicum DM4 was first demonstrated. The sequence of the only XoxF homolog found in the genome of strain DM4 exhibited 50% identity to that of the protein (MxaF) of the large subunit of(More)
