| Abstract/Contents: | Azospirillum lipoferum isolated from Carex pallescens and red fescue roots, Enterobacter agglomerans from Calamagrostis arundinacea, Achillea millefolium, Phalaris arundinacea and timothy, Enterobacter sp. from Elytrigia repens, Klebsiella pneumoniae from Agrostis stolonifera, C. pallescens, P. arundinacea and Poa pratensis and Pseudomonas sp. from Deschampsia cespitosa were studied. The best substrate for the facultative anaerobic genera, Klebsiella and Enterobacter, was sucrose, followed by fructose and mannitol. The obligate aerobic genera Azospirillum and Pseudomonas did not use disaccharides and performed best on malate and glucose. Isolates from P. arundinacea were unable to utilize lactose. N fixation was greatest in the presence of O2 for all aerobic isolates and in the abscence of O2 for anaerobic isolates except for E. agglomeratum from P. arundinacea. |
