The nodules are home to symbiotic bacteria, called rhizobia, that take nitrogen from the air and turn it into ammonia, a nitrogen compound that plants can use readily.
At the same time, the increasing quantity of Chile saltpetre used to make gunpowder led to a worldwide search for natural deposits of this nitrogen compound.
The well-known Kjeldahl method for determining the nitrogen content of organic compounds involves digestion of the compound with concentrated sulfuric acid (optionally containing mercury, or its oxide, and various salts, depending on the nature of the nitrogen compound).
Public safety and the health of coastal ecosystems have also improved as a result of sea-grant studies, such as those examining nitrogen compound runoff, Great Lake contaminants, zebra mussel proliferation, and marine safety and lifesaving techniques.
Like the other nitrogenous components of nucleic acids, thymine is part of thymidine, a corresponding nucleoside (a structural unit composed of a nitrogen compound and a sugar), in which it is chemically linked with the sugar deoxyribose.
Nitrates were the most abundant form of nitrogen compound.
Furthermore, the employment of NH4Cl solely required the analysis of one nitrogen compound.
So, this decontaminated wastewater containing nitrogen compound could be used for irrigation.
Alkylcarbazoles represented a significant portion of the nitrogen compound contribution to the polar fraction isolated from diesel.
Alkyl-substituted carbazoles are found to be the dominant and most refractive organic nitrogen compound in the feed.
The present results have also provided insight into the nitrogen compound inhibition of the direct desulfurization DDS pathway.
