摘要： An object of the present disclosure is at least to provide a technique for promoting elimination of a methyl group(s) of a methoxy group(s) in causing a microorganism having a demethylation ability of eliminating a methyl group(s) of a methoxy group(s) from a compound with the methoxy group(s) in a side chain(s) to produce a demethylated compound in which a methyl group(s) of a methoxy group(s) has eliminated from a compound with the methoxy group(s) in a side chain(s). The issue is solved by a method for producing a demethylated compound, comprising co-culturing, in a solution containing a compound with a methoxy group(s) in a side chain(s), a microorganism having a demethylation ability of eliminating a methyl group(s) of a methoxy group(s) from a compound with the methoxy group(s) in a side chain(s), and a microorganism having an activity to promote the demethylation, to produce the demethylated compound in which a methyl group(s) of a methoxy group(s) has eliminated from the compound with the methoxy group(s) in the side chain(s).

摘要： Disclosed is a process for the production of a desired oligosaccharide, the process comprises providing a genetically engineered microbial cell which possesses a saccharide importer for the uptake of an intermediate oligosaccharide, and an enzyme being able to convert the intermediated oligosaccharide by transferring a monosaccharide moiety from a donor substrate to the intermediate oligosaccharide; cultivating the genetically engineered microbial cell in the presence of an intermediate oligosaccharide to generate the desired oligosaccharide; and retrieving the desired oligosaccharide.

摘要： A recombinant microorganism of the genus Escherichia, comprises a genetic modification that increases expression of a nosZ gene encoding NosZ, which is a nitrous oxide reductase, in the recombinant microorganism, wherein the recombinant microorganism comprises a nosR gene encoding NosR, a nosD gene encoding NosD, a nosF gene encoding NosF, a nosY gene encoding NosY, and an apbE gene encoding ApbE, and wherein the nosR gene, the nosD gene, the nosF gene, the nosY gene and the apbE gene are derived from a microorganism of the genus Pseudomonas, the genus Paracoccus, or a combination thereof.
