Azotobacter spp

The presence of microorganisms in the rhizosphere has been shown to increa.se root exudation (58,61-65). This stimulation of exudation has been shown to occur in the pre.sence of free-living bacteria such as Azospirillum spp. and Azotobacter spp. (66,67) and in the presence of symbiotic organisms such as mycorrhizae (68,69). Increased root exudation has also been shown to be species-specific for example Meharg and Killham (65) found that metabolites produced by Pseudomonas aeru/ inosa stimulated a 12-fold increase in C-labeled exudates by perennial ryegrass. However, under the same conditions, metabolites from an Arthro-bacter species had no effect on root exudation. [Pg.103]

The PHB is one of the commercially available PHAs which find multiple applications in Food Industry. Polymer of 3-hydroxybutyrate, have been introduced into the market in relatively large quantities as bioplastic material. The PHB is accumulated as intracellular granules by many prokaryotic organisms (including /ca//gene5 spp.. Bacillus spp., Azotobacter spp., Pseudomonas spp.) as they enter the stationary phase of growth, to be used later as an internal reserve of carbon and energy... [Pg.163]

The cytochrome o from Azotobacter vinelandii is reported to consist of one polypeptide of molecular weight 28 000 with two identical heme components. It has also been isolated from the thermophile PS3,1319 Escherichia coli, Vitreoscilla, Pseudomonas aeruginosa, and Rhodopseudomonas spp. The enzyme from Vitreoscilla consists of two identical polypeptides of molecular weight 13 000 and two moles of protoheme IX. A cytochrome b562-o complex from E. coli contains two peptides and, strangely, copper.1320... [Pg.697]
