Abstract
The products of CO2 fixation by heterotrophically grown Haloferax mediterranei were analysed. The main 14C-labelled alpha-ketoacid detected following incubation with NaH14CO3 and pyruvate or propionate was pyruvate. In presence of these organic acids and NH4+, 14CO2 was incorporated into glutamic and aspartic acids and alanine.
摘要
对异养生长的地中海嗜盐菌固定二氧化碳的产物进行了分析。在用NaH¹⁴CO₃与丙酮酸或丙酸孵育后检测到的主要¹⁴C标记的α-酮酸是丙酮酸。在这些有机酸和NH₄⁺存在的情况下，¹⁴CO₂被掺入谷氨酸、天冬氨酸和丙氨酸中。
