Abstract:

In a non-growing population of an arginine-requiring auxotroph of Escherichia coli, the uptake of [14C] arginine and [14C]glucose by the whole organisms, and the incorporation of [l4C] arginine in the acid-soluble fraction and total protein of the organisms, decreased with increasing bacterial concentration in a wide range (0.1-3.0 mg. dry wt. bacteria/ml.). It is concluded that the rate of transport/organism of arginine and glucose decreased with increasing bacterial concentration.
