Chemical Activities of E. coli Adsorbed on a Resin, ‘Dowex-I’

Abstract

CHEMICAL activites of bacteria are affected by a number of environmental variables, among which pH, substrate concentration and temperature are the most important. If around a particle of a resin there are ionic layers deep enough to cover any bacterial cells adsorbed on the resin, one would not expect that the dependence of an activity of the cells on pH and substrate concentration will be the same for the adsorbed cells as for the cells freely suspended in solution, as McLaren has pointed out in the case of enzymes1.
