Pathways of ammonia assimilation into glutamic acid in Bacillus azotofixans, a recently characterized nitrogen-fixing species of Bacillus, were investigated through observation by NMR spectroscopy of in vivo incorporation of 15N into glutamine and glutamic acid in the absence and presence of inhibitors of ammonia-assimilating enzymes, in combination with measurements of the specific activities ...

Canola (Brassica napus L. var. oleracea) is the third most common oil-producing crop worldwide after palm and soybean. cultivation requires use of chemical fertilizers, but amount required can be reduced by applying plant growth-promoting bacteria (PGPB). Among PGPB, endophytic have certain advantages as biofertilizers, canola rarely been studied. In this work, we identified a collection bacter...

BACKGROUND Paenibacillus polymyxa is a bacterium widely used in agriculture, industry, and environmental remediation because it has multiple functions including nitrogen fixation and produces various biologically active compounds. Among these compounds are the antibiotics polymyxins, and the bacterium is currently being reassessed for medical application. However, a lack of genetic tools for ma...
