title: Catalase induction in non-proliferating suspensions of Pseudomonas fluorescens (type R.). I. Influence of the buffer.
abstract: The catalasic activity of a non-proliferating suspension of Pseudomonas fluorescens incubated in a buffer shows after six hours, an increase of 100% in presence of phosphates and 30% in presence of Tris. This increase, which consists in a neosynthesis of the enzyme, is in relation with the lysis of a part of the bacterial suspension.
