Abstract
Escherichia coli and Pseudomonas aeruginosa were grown at several temperatures ranging from 0° to 37 °C and assayed at each temperature for L-serine dehydratase activity. The relationship between enzymatic activity and growth temperature is quite different for the mesophile and psychrophile. In addition, the stimulatory effect of natural plant lecithin upon serine deamination was different for each organism, suggesting that there is either a difference in permeability or that this substance has a more direct role in enzymic activity. Also included are data confirming the results of other workers.This publication has 20 references indexed in Scilit:
