GROWTH OF NON STARTER LACTIC ACID BACTERIA IN REDUCED FAT CHEESE

本研究旨在研究蛋氨酸的催化作用 在乳酸菌中产生甲硫醇。 两种途径是 参与category：1）？，？-硫代胱氨酸消除法 ?-裂合酶和2）转氨作用。 使用DMX 400 MHz的13 C NMR 光谱仪应该可以区分这两者 以及两条路径之间的可能分布。

This study is designed to investigate the catabolism of methionine in lactic acid bacteria to produce methanethiol. Two pathways are involved in the catabolism: 1) ?,?-elimination by cystothionine ?-lyase and 2) transamination. 13C NMR using the DMX 400 MHz spectrometer should yield a way to differentiate between the two pathways as well a the possible distribution between the two pathways.
