Genomes of the symbiotic nitrogen-fixing bacteria of legumes.
Over the last several decades, there have been a large number of studies done on the genetics, biochemistry, physiology, ecology, and agronomics of the bacteria forming nitrogen-fixing symbioses with legumes. These bacteria, collectively referred to as the rhizobia, are taxonomically and physiologically diverse members of the a and b subclasses of the Proteobacteria, and mostly comprise members...
متن کاملStudies of aerobic non-symbiotic nitrogen-fixing bacteria.
The occurrence of aerobic, non-symbiotic, nitroqen-fixing bacteria was determined in samples of soil collecte~l in the various soil zones of Allxrm and Saslcatchewan. Mannitol and sodiuttl betuoate dust-platrs. and mallnit01 solution cultures wiLh subsequent inoculation onto rnannitol agar demonstrated that Asolohnrtt-r were not wirlcspreatl in the Canadian prairie province soils. These r)n)ccr...
متن کاملCorals form characteristic associations with symbiotic nitrogen-fixing bacteria.
The complex symbiotic relationship between corals and their dinoflagellate partner Symbiodinium is believed to be sustained through close associations with mutualistic bacterial communities, though little is known about coral associations with bacterial groups able to fix nitrogen (diazotrophs). In this study, we investigated the diversity of diazotrophic bacterial communities associated with t...

متن کاملExopolysaccharides produced by lactic acid bacteria of kefir grains.
A Lactobacillus delbrueckii subsp. bulgaricus HP1 strain with high exopolysaccharide activity was selected from among 40 strains of lactic acid bacteria, isolated from kefir grains. By associating the Lactobacillus delbrueckii subsp. bulgaricus HP1 strain with Streptococcus thermophilus T15, Lactococcus lactis subsp. lactis C15, Lactobacillus helveticus MP12, and Sacharomyces cerevisiae A13, a ...
