Show all pathways known for 4.1.3.3Display the word mapDisplay the reaction diagram Show all sequences 4.1.3.3-999 - - 33314, 33316, 33319, 33321, 33325
Show all pathways known for 4.1.3.3Display the word mapDisplay the reaction diagram Show all sequences 4.1.3.3-999 - after a 36 h incubation, the concentrations of N-acetyl-D-neuraminic acid from the reactions utilizing 0.4, 0.8, 1.2, 1.6, 2.0, and 2.2 M pyruvate as the carbon source are 7.5 (3.75%), 26.9 (3.45%), 43.9 (21.95%), 56.0 (28%), and 61.9 mM (30.95%), respectively. When using 2.2 M pyruvate, in the first 6 h, the concentration of N-acetyl-D-neuraminic acid reaches 29.5 mM (which is about half of the maximal concentration), and the productivity of N-acetyl-D-neuraminic acid is 1.6 g/l/h, the concentration of the intermediate N-acetyl-D-mannosamine also increases gradually from 0 to 64 mM during the process 701881
