Effects of methanol on the synthesis of aspartame precursor catalysed by Pseudomonas aeruginosa elastase
Pseudomonas elastase was found to be efficient in catalysing the reaction between N-benzyloxycarbonyl-L-aspartic acid and L-phenylalanine methyl ester producing the aspartame precursor in aqueous and aqueous methanolic solutions. 25% (v/v) methanol was most favourable for the synthesis where about 1...

| description | Pseudomonas elastase was found to be efficient in catalysing the reaction between N-benzyloxycarbonyl-L-aspartic acid and L-phenylalanine methyl ester producing the aspartame precursor in aqueous and aqueous methanolic solutions. 25% (v/v) methanol was most favourable for the synthesis where about 100% increase in yield was obtained compared to that in aqueous solution. |
