…of nitrogen-fixing microorganisms are recognized: free-living (nonsymbiotic) bacteria, including the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium; and mutualistic (symbiotic) bacteria such as Rhizobium, associated with leguminous plants, and various Azospirillum species ...

12 Οκτ 2024 · Two kinds of nitrogen-fixing bacteria are recognized. The first kind, the free-living (nonsymbiotic) bacteria, includes the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium.
13 Απρ 2021 · Zou, S., Zhang, Q. & Gong, J. Comparative transcriptomics reveals distinct gene expressions of a model ciliated protozoa feeding on bacteria-free medium, digestible, and digestion-resistant...
Although organisms such as Azospirillum usually produce acetic acid, it is a free-living nitrogen-fixing bacteria that ensures that the entire nitrogen-fixing process is well-regulated. Free-living nitrogen-fixing bacteria examples include Anabaena, Cyanobacteria, Clostridium and Beijerinckia.
Nitrogen-fixing bacteria are grouped into free-living bacteria (Azotobacter and Azospirillum) and the blue-green algae and symbionts, for example, Rhizobium, Azolla, and Frankia (Gupta, 2004). However, many bacteria have been associated with non-legumes plants ( Mohammadi and Sohrabi, 2012 ).
These prokaryotes include aquatic organisms, such as cyanobacteria, free-living soil bacteria, such as Azotobacter, bacteria that form associative relationships with plants, such as Azospirillum...
24 Μαρ 2017 · Our data imply that free-living nitrogen-fixing bacteria could convert the easy-used carbon sources to exopolysaccharides in order to enable nitrogen fixation in a natural aerobic environment.
