抜粋

Microbioassay of phenylalanine in sera is carried out by incubation with Leuconostoc mesenteroides (6 h) followed by use of a lactate electrode (immobilized lactate oxidase and an oxygen electrode) to measure the lactate produced. A linear relationship is obtained between the current decrease and the phenylalanine concentration between 0.75 and 6 × 10-7g ml-1 , with a standard deviation of 1.7 × 10-8 g ml-1 at the 3 × 10-7 g ml-1 level.
