BACKGROUND Nitrilase is an important member of the nitrilase superfamiliy. It has attracted substantial interest from academia and industry for its function of converting nitriles directly into the corresponding carboxylic acids in recent years. Thus nitrilase has played a crucial role in production of commercial carboxylic acids in chemical industry and detoxification of nitrile-contaminated w...

Carboxylic acids are an attractive biorenewable chemical in terms of their flexibility and usage as precursors for a variety of industrial chemicals. It has been demonstrated that such carboxylic acids can be fermentatively produced using engineered microbes, such as Escherichia coli and Saccharomyces cerevisiae. However, like many other attractive biorenewable fuels and chemicals, carboxylic a...

To identify the larvicidal activities of silver nanoparticles synthesized with Acanthus ilicifolius (A. ilicifolius) leaf extract against the larvae of Armigeressubalbatus and Aedesaegypti. In vitro larvicidal activities such as LC50 and LC90 were assessed for the A. subalbatus  and Ae.aegypti larval species. F...

A total of 20 biogenic carboxylic acids, which contain one to three negatively charged -COOgroup(s), were investigated as dispersion additives in the processing of ceramic particles. Only carboxylic acids containing one or more hydroxyl groups were able to disperse ct-A120 3 particles in aqueous suspensions. Detailed studies of two carboxylic acids, citric acid and tricarballylic acid were unde...

Oxidation of acenaphthene, acenaphthylene, and fluorene was examined with recombinant strain Pseudomonas aeruginosa PAO1(pRE695) expressing naphthalene dioxygenase genes cloned from plasmid NAH7. Acenaphthene underwent monooxygenation to 1-acenaphthenol with subsequent conversion to 1-acenaphthenone and cis- and trans-acenaphthene-1,2-diols, while acenaphthylene was dioxygenated to give cis-ace...

Synthesis and characterization of a polymethine cyanine near-infrared (NIR) fluorophoric label for the derivatization and determination of fatty acids separated by capillary electrophoresis are described. The label contains an aromatic amine functionality, which is used to form a covalent linkage with the analyte. Various linking chemistries are explored, including direct amine–acid condensatio...
