The effect of different diatomite concentrations on L-dopa production by Y. lipolytica NRRL-143 (L-tyrosine consumed -∘-, L-Dopa produced -×-). A total of 3.5 mg/ml L-tyrosine, 3.0 mg/ml cell biomass and varying diatomite amounts were added at the start of the biochemical reaction. The total reaction time was 50 min at 50°C.
