Abstract:
The invention relates to a method for the step-wise oxidation of aromatic compounds to the corresponding aldehyde and/or carboxylic acid derivatives using genetically engineered microorganisms that express xylol monooxygenase or alkane monooxygenase.
Abstract:
A method comprising the indirect electrochemical regeneration of NAD(P)H in enzymatic substrate conversions which are catalyzed by monooxygenases is described. In particular, a method for the electroenzymatic preparation of 2,3-dihydroxyphenyl derivatives, which is catalyzed by the enzyme 2-hydroxybiphenyl 3-monooxygenase and in which simultaneously the NAD+ formed by reductive cleavage of oxygen is electrochemically reduced, is described.
Abstract:
Production of aromatic aldehyde or carboxylic acid (I) by culturing a microorganism that expresses xylene mono-oxygenase (XMO) or alkane mono-oxygenase (AMO) in a medium containing an aromatic substrate (II). Production of aromatic aldehyde or carboxylic acid of formula (I) by culturing a microorganism that expresses xylene mono-oxygenase (XMO) or alkane mono-oxygenase (AMO) in a medium containing an aromatic substrate of formula (II). [Image] Ar : monocyclic aromatic ring, optionally with one or more substituents; R 1>formyl or carboxy; n : 0-15; R 2>vinyl or (CH 2) m-R 3>, also where R 1>= carboxy, R 2>may be (CH 2) n-CHO; m : n+1; and R 3>hydrogen or hydroxy. Independent claims are also included for the following: (a) recombinant microorganism harboring an expression vector that contains, under control of the alk-regulatory system of Pseudomonas oleovoransGpol, the XMO-encoding genes xylM and xylA, or the AMO-encoding genes alkB, alkG and alkT; and (b) expression construct containing the genes specified in (a), operably linked to the alk-regulatory system.
