The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Picolinamide( cas:1452-77-3 ) is researched.Electric Literature of C6H6N2O.Nie, Zimeng; Yan, Binghua; Xu, Yunhai; Awasthi, Mukesh Kumar; Yang, Haijun published the article 《Characterization of pyridine biodegradation by two Enterobacter sp. strains immobilized on Solidago canadensis L. stem derived biochar》 about this compound( cas:1452-77-3 ) in Journal of Hazardous Materials. Keywords: pyridine biodegradation wastewater treatment morphol phys chem property; Biodegradation; Immobilization; Intermediates; Metabolic pathway; Mineralization. Let’s learn more about this compound (cas:1452-77-3).
In this study, two pyridine-degrading strains namely Enterobacter cloacae complex sp. BD17 and Enterobacter sp. BD19 were isolated from the aerobic tank of a pesticide wastewater treatment plant. The mixed bacteria H4 composed of BD17 and BD19 at a ratio of 1:1 was immobilized by Solidago canadensis L. stem biochar with a dosage of 2 g·L–1. The highest pyridine removal rate of 91.70% was achieved by the immobilized H4 at an initial pyridine concentration of 200 mg·L-1, pH of 7.0, temperature of 28°C and salinity of 3.0% within 36 h. The main intermediates of pyridine degradation by BD17 were pyridine-2-carboxamide, 2-aminopropanediamide, and 2-aminoacetamide, while 2-picolinic acid, iso-Pr acetate, iso-Pr alc., and acetaldehyde were identified with BD19 by adopting GC-MS technique. Interestingly, there was a possibility of totally mineralization of pyridine and the corresponding degradation pathways of BD17 and BD19 were revealed for the first time.
There is still a lot of research devoted to this compound(SMILES：O=C(N)C1=NC=CC=C1)Electric Literature of C6H6N2O, and with the development of science, more effects of this compound(1452-77-3) can be discovered.
