Physiological and genetic characterization of fluorescent Pseudomonas associated with Cantharellus cibarius.

abstract：:The induction of nitrogenase (C2H2) activity in asymbiotically cultured Rhizobium sp. 32H1 was found to be associated with morphological changes in the cells which were more pronounced than those seen in bacteroids. Polyphosphate granules were found in both bacteroids and cultured cells, but poly-beta-hydroxybutyrate ...
