Abstract
Pantothenate synthesis from pantothenate and β-alanine by the washed cell suspension of Escherichia coli was investigated. From these precursors resting cells of E.coli 0-20 wild strain synthesized a large amount of pantothenate under a vigorous aeration in the presence of glucose. No significant amount of pantothenate, however, was synthesized by the two mutant strains, responding only to the preformed vitamin.
