. 2013 Sep;
111(3):537-44.
PMID: 23996152
Production of organic acids in solid-liquid two-phase partitioning bioreactors (TPPBs) is challenging, and highly pH-dependent, as cell growth occurs near neutral pH, while acid sorption occurs only at low pH...

PMID: 23907719
The biotransformation of levulinic acid to 4-valerolactone (4VL) is pH-dependent and equilibrium limited, distinct from the more common irreversible biotransformations that are constrained by product toxicity or biocatalyst inhibition. Our...
