The asymmetric transformation of L-Pro via the formation of salt with S-tartaric acid was carried out by butanal as catalyst and butanoic acid as solvent to obtain D-Pro · S-TA salt.

實驗研究了L一Pro的消旋反應，并獲得刀乙一脯氨酸，然后在消旋的基礎上研究L一Pro的不對稱轉(zhuǎn)換，最后得到D一Pro。

The metabolites were mainly aldehydes and acids when the level of inoculation was 10~9cfu/ml, however, alcohols, acids and esters were produced when the level of inoculation was 10~8cfu/ml. The optimal temperature and pH for production of 3-methyl butanal were 40℃ and 7.0, but NaCl and NaNO_2 inhibited its production.
