A recombinant microorganism which has been transformed with

• (a) a nucleotide sequence encoding a phosphoric monoester hydrolase (EC 3.1.3.-);
• and
• (b) a nucleotide sequence encoding an enzyme selected from the group consisting of
• (i) an aldehyde lyase (EC 4.1.2.-);
• and/or
• (ii) a transaldolase (EC 2.2.1.2).
