Formation of N-nitrosodimethylamine by Escherichia coli

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Potential enhanced N-nitrosodimethylamine (NDMA) formation under water treatment conditions

This study investigates two aspects of NDMA formation reactions: (i) evaluation of the potential effect of formaldehyde on NDMA formation, particularly in reactions of dimethylamine (DMA) and nitrite, and (ii) assessment of potential NDMA formation from a range of polymeric coagulants and flocculants upon exposure to disinfection oxidants. The results show that the presence of formaldehyde can ...

Case Report of Meningoencephalitis in Calves Caused by Escherichia coli

Hydroxamate formation by anthranilate synthetase of Escherichia coli K12.

HO' H /H2 0 \ I dOOH chorismic acid anthranilic acid (Gibson and Gibson, 1964; Somerville, unpublished results). In Escherichia coli the catalytically active species is a protein complex formed by aggregation of the products of the E and D genes of the tryptophan operon (Ito and Yanofsky, 1966). Anthranilate synthetase is one of a class of amidotransferase enzymes where L-glutamine serves as th...
