Abstract:
Pseudomonas sp. TS1138 isolated from soil samples was able to form L-cysteine from DL-2-Amino-△2-Thia-zoline-4-Carboxylic Acid (DL-ATC) after cultured 16 hours . The optimum carbon and nitrogen soruces of strain growth and enzyme formation are glucose and urea. This enzyme was induced by DL-ATC. The product was identified to be L-Cysteine based on thin layer chromatography, optical rotation and HPLC studies.
