Results and discussion
Any other information on results incl. tables
Methanesulphonic acid is the simplest of the sulfonates and is a substrate for the growth of certain methylotrophic microorganisms. Such as the facultative methylotroph bacterium Methylosulfonomonas methylovora, which was isolated from garden soil, or the bacterium Marinosulfonomonas methylotropha, which was isolated from the marine environment.
In a first step methanesulphonic acid gets oxidized to formaldehyde, which can then be either assimilated through the serin cycle or fully oxidized to yield CO2 and H2O in order to produce reduction power and energy for the cell. It was shown that the inducible enzyme responsible for the oxidation of methanesulphonic acid is a multicomponent monooxygenase. The multicomponent monooxygenase appears from its substrate specificity to be a unique oxygenase with a rather narrow substrate range. O2 consumption studies and cell extract assays demonstrated a restricted substrate range that includes only short-chain aliphatic sulfonates (methane- to butanesulfonate) and excludes all larger molecules.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
