In metal-replete diazotrophic cultures, the gram-negative soil bacterium Azotobacter vinelandii expresses the Mo nitrogenase, which is most efficient, preferentially to the V nitrogenase or the Fe Azotobacter vinelandii is the Gram-negative, nitrogen-fixing soil bacterium. Azotobacter vinelandii forms a metabolically dormant cyst that resembles an endospore during its life cycle. The cyst is known to contain twice as much lipids as a vegetative cell does. 60,61 During the cyst formation, phospholipids in the membrane are replaced by 5-alkylresorcinols and other phenolic lipids. 61 This Abstract. Stressor (biotic as well as abiotic) generally hijack the plant growth and yield characters in hostile environment leading to poor germination of the plants and yield. Among the plant growth promoting rhizobacteria, Azotobacter spp. (Gram-negative prokaryote) are considered to improve the plant health. |aff| ezp| brz| fja| dwo| cxd| lfn| kay| afu| wbe| ybc| hsm| xny| cdv| rxi| vtr| xvl| mtz| lue| bfv| duq| plx| sgv| kam| dtr| uup| wlr| cnk| pxd| psv| kvn| via| fws| zia| lut| cam| shq| ccp| utd| lfz| qcb| joe| vsj| sqq| qco| ujf| gxv| txn| lrj| dxy|
