pH Regulation of Ammonia Secretion by Colletotrichum gloeosporioides and Its Effect on Appressorium Formation and Pathogenicity

Molecular Plant-Microbe Interactions, 2010
Host-tissue alkalinization via ammonia accumulation is key to Colletotrichum spp. colonization. Using macroarrays carrying C. gloeosporioides cDNAs, we monitored gene expression during the alkalinization process.

Studies on the use of supercritical ammonia for ceramic nitride synthesis and fabrication [PDF]

The extractability of ammonia halides (including ammonium thiocyanate) formed as byproducts from the synthesis of Si(NH)2 via ammonolysis of the corresponding silicon tetrahalides using supercritical NH3 as the extraction medium was investigated.

Minimal ureagenesis is necessary for survival in the murine model of hyperargininemia treated by AAV-based gene therapy. [PDF]

, 2014
Hyperammonemia is less severe in arginase 1 deficiency compared with other urea cycle defects. Affected patients manifest hyperargininemia and infrequent episodes of hyperammonemia. Patients typically suffer from neurological impairment with cortical and

Simulation of Ammonia Synthesis [PDF]

American Journal of Chemical Engineering, 2013
Ammonia is prodeuced to give a final product named urea which is a very important fertilizer for higher nitrogen content.Several processes has been invented for optimum production of ammonia. Now-a-days, Ammonia production is mainly done by Haber process in which nitrogen andhydrogen react in the presence of an iron catalyst to form ammonia.

Inducible arginase 1 deficiency in mice leads to hyperargininemia and altered amino acid metabolism [PDF]

, 2013
Arginase deficiency is a rare autosomal recessive disorder resulting from a loss of the liver arginase isoform, arginase 1 (ARG1), which is the final step in the urea cycle for detoxifying ammonia. ARG1 deficiency leads to hyperargininemia, characterized

A Century of Synthetic Fertilizer: 1909-2009 [PDF]

, 2009
This year marks a centenary of the synthetic fertilizer industry. German chemists, Fritz Haber and Carl Bosch, in 1909 demonstrated their industrial process for the manufacture of ammonia. The achievement won them accolades including Nobel Prizes.
