The efficiency factor, the number of moles of ATP generated per mole of glucose fermented, was determined in anaerobic, non-carbon-limited N2-fixing cultures of Bacillus polymyxa, Bacillus macerans, Bacillus azotofixans, and Clostridium butyricum through identification and quantitation of the fermentation products by 13C nuclear magnetic resonance spectroscopy and measurement of acetate kinase ...

Pathways of ammonia assimilation into glutamic acid and alanine in Bacillus polymyxa were investigated by "N NMR spectroscopy in combination with measurements of the specific activities of glutamate dehydrogenase, glutamine synthetase, glutamate synthase, alanine dehydrogenase, and glutamic-alanine transaminase. Ammonia was found to be assimilated into glutamic acid predominantly by NADPH-depen...

The study aims at assessing the potentials of some new salt-tolerant isolates as plant growth-promoting rhizobacteria (PGPR) under saline condition. Three 165 that grew on presence 2-20% NaCl were high and had many features PGPR. They identified by using 16S rRNA gene sequencing. nearest species to our Paenibacillus polymyxa (GQ375783.1), Ochrobactrum intermedium (MG309678.1) Enterobacter cloac...
