title: Pseudomonas fluorescens var. aluphilia--the influence of Al3+ on the growth rate and formation of phenazines.
abstract: The thin-layer chromatographic characterization of phenazine derivatives formed by a subspecies of Pseudomonas fluorescens under iron deficiency conditions in the presence of Al3+ showed that regarding type and quantity they were relatively different from phenazines generated on the basis of Be(2+)-containing culture media or containing neither Be2+ ions nor Al3+ ions. A comparison has shown that bacterial synthesis of phenazine derivatives is stimulated more by Be2+ ions than by Al3+ ions.
