The present disclosure provides recombinant microorganisms and methods for the anaerobic production of 2,4-furandimethanol from one or more carbon sources. The microorganisms and methods provide redox-balanced and ATP positive pathways for co-producing 2,4-furandimethanol with ethanol and for co-producing 2,4-furandimethanol with ethanol and acetone and/or isopropanol. The method provides recombinant microorganisms that express endogenous and/or exogenous nucleic acid molecules encoding polypeptides that catalyze the conversion of a carbon source into 2,4-furandimethanol and that couple the 2,4-furandimethanol pathway with an additional metabolic pathway. The present disclosure further provides enzymatic production of 2,4-furandicarboxylic acid.

The present invention provides a bacterium and a method for the biological production of Heliotropin by the fermemtation of safrole. In one aspect of the present invention, a process for the conversion of safrole to Heliotropin is achieved by the use of a bacterial strain of Serratia liquefaciens ZMT-1 (CCTCC M 2016170). The production method comprises the steps of seeding the Serratia liquefaciens culture in the presence of oxygen for 24-36 hours, transforming the safrole substrate for 24-48 hours with 0.5-3 g/L substrate concentration, and reaching the Heliotropin concentration of 160-524 mg/L. The present invention reports, for the first time, on a method for producing the high concentration of Heliotropin by using the Serratia liquefaciens ZMT-1 strain or the enzyme extracted from the strain.
