Abstract excerpt
The physiological behaviour of Pseudomonas fluorescens strain R2fN was compared to that of transconjugants [R2fN(RP4)], and two aggregation phenotypes were identified (Agr- and Agr+). Agr+ phenotype is characterized by the appearance of macroscopic aggregates when cells are growing in liquid media. Transconjugants exhibited Agr+ phenotype whereas wild type strain represented Agr-. Evidence is presented to support...
