摘要:
The ability of Clostridium butyricum cultures to hydrolyze three L-leucine-containing dipeptides (Leu-Leu, Leu-Gly and Gly-Leu) in a synthetic minimal medium is demonstrated by using gas chromatography coupled with mass spectrometry. The C-13 nuclear magnetic resonance and a labeled dipeptide L-[1-C-13]Leu-Gly were used to confirm this activity. (C) 1998 Elsevier Science Ltd. All rights reserved.
