a, b, c, d, e: Different letters in a same raw indicate the data are significantly different as evaluated by Tukey test (p<0.01). The bioconversion medium is sterilized water containing 0.15 g/L glucose. The data were obtained after bioconversion for 40 h. The abbreviations are leucine (Leu), threonine (Thr), lysine (Lys), the aromatic amino acids phenylalanine (Phe) and tyrosine (Tyr), and the heterocyclic amino acids tryptophan (Trp) and histidine (His).
