Modification of Solubility of Cholesterol During Incubation with Growing Cells of Aerobacter aerogenes. ∗

Summary

C¹⁴-labeled cholesterol was incubated with growing cells of A. aerogenes. Following hydrolysis of the incubation medium, a significant portion of the sterol was recovered in the saponifiable fraction. Apparently, the solubility of the sterol was modified by a substance produced during the growth of the Aerobacter.
