Dependence of vanillin production on the stage of cell growth. Bioconversion experiments were carried out using JM109(pBB1) cells [4 g(wet weight)/L] at different stage of growth. Resting cells were incubated for 1 h in the presence of 0.5 mM ferulic acid and the production of vanillin was determined by HPLC analysis.
