Evaluation of nitrogen sources for the propagation of A. niger GCBT-8 for L-dopa production. a) Peptone, b) Yeast extract, c) ammonium chloride. Glucose conc. 6% (w/v), propagation time 48 h, initial pH 5.5. Standard bars indicate standard deviation (± sd) among the three parallel replicates (L-tyrosine consumed - × -, L-dopa produced - -).
