Hydrogenase-mediated reduction of flavin mononucleotide by H 2 is exploited to enable cleaner application nitroreductase enzymes for aromatic nitro functional groups. This turns the overall reaction into a biocatalytic hydrogenation. Use flavin-containing nitroreductases in industrial biotechnology typically relies upon NADH or NADPH as reductant, together with glucose dehydrogenase and regener...

Porous carbon with a foam-like microstructure has been synthesized by direct carbonization of porous coordination polymer (PCP). In situ generation of foaming agents by chemical reactions of ligands in PCP during carbonization provides a simple way to create lightweight carbon with a foam-like microstructure. Among several substituents, the nitro group has been proved to be the key to obtain th...

A large number of interesting organocatalytic enantioselective protocols have been explored and successfully applied in the last decade. Among them, the Henry (nitroaldol) reaction represents a powerful carbon-carbon bond-forming procedure for the preparation of valuable synthetic intermediates, such as enantioenriched nitro alcohols, which can be further transformed in a number of important ni...

We applied natural abundance stable isotope δ13C and radiocarbon ∆14C analyses to investigate trophic linkages between zooplankton and their potential food sources (phytoplankton, submersed plants, and allochthonous organic carbon) in Lake Nam Co, one of the largest oligosaline and oligotrophic lakes in the Tibetan Plateau, in south-west China. The δ13C and ∆14C levels of the calanoid copepod A...

Copper (II) phthalocyanine and 2, 9, 16, 23 tetrakis nitro copper (II) phthalocyanine has been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalysts over nanodimensional zeolites. 4-Nitro phthalonitrile synthesized from phthaimide in three steps. The newly prepared compounds have been characterized by IR, UV-Vis,1H N...

in the present study, four carbon sources were tested for the polyester synthesis of pseudomonas aeruginosa pa01 which is a ubiquitous environmental bacterium and is one of the top three causes of opportunistic human infections. these included linear c8 to c11 carboxylic acids. octanoic acid, nonanoic acid, decanoic acid and undecanoic acid were added to m1 minimal medium to final concentration...

In this article, we consider the growth of microorganisms on mixtures of carbon sources and characterize the consumer-resource relationship for this system. The characteristic features observed for the growth of a single microorganism on a pair of carbon sources allow a representation of this relationship based on a general paradigm for resource classification. This representation is verified u...

We present improved correlations between theoretical and experimental determination of heat of formation of some aliphatic nitro compounds. The method is based on a previously given theoretical procedure, which is ameliorate through the introduction of suitable bond parameters. The comparison with available experimental data and previous theoretical estimation show a quite satisfactory improvem...
