Glucose triggers ATP secretion from bacteria in a growth-phase-dependent manner.

abstract：:Tn5 insertion mutants of a soil isolate, Pseudomonas fluorescens Pf0-1, were selected for decreased ability to adhere to quartz sand in a column assay. Three adhesion-deficient mutants that differed in the location of the Tn5 insertion in the chromosome were isolated and compared with the wild-type strain. One mutant,...
