The effect of various levels of cell biomass (Y. lipolytica NRRL-143) on L-dopa production (L-tyrosine consumed -∘-, L-Dopa produced -×-). a. Control (3.5 mg/ml L-tyrosine only). b. Test (3.5 mg/ml L-tyrosine and 2.0 mg/ml diatomite added 15 min after the start of reaction), The total reaction time was 50 min at 50°C.
