FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology. Claimed is method for obtaining aldehydes. Glycerol or 1,2-propanediol and hydro-lyase, selected from glycerol-dehydratases, diol-dehydratases and propanediol-dehydratases are brought in contact. Cells of microorganisms, possessing hydro-lyase activity can be also used. Compound, which forms bond with aldehyde and is selected from the group, including sulphites, metabisulphites and pyrosulphates, is added. Suspension is incubated. After that, formed aldehyde and hydro-lyase are separated. Previous stages are repeated with participation of hydro-lyase. In case of necessity separation of formed aldehyde is realised.
EFFECT: invention makes it possible to increase aldehyde output and reduce decrease of survival of cells, possessing hydro-lyase activity, in reaction medium.
