degradation of phenanthrene via meta cleavage of 2 hydroxy 1 Naphthoic Acid by ochrobactrum sp strain pwtjd
Fems Microbiology Letters, 2010Co-Authors: Debajyoti Ghosal, Joydeep Chakraborty, Pratick Khara, Tapan K. DuttaAbstract:The present study describes the assimilation of phenanthrene by an aerobic bacterium, Ochrobactrum sp. strain PWTJD, isolated from municipal waste-contaminated soil sample utilizing phenanthrene as a sole source of carbon and energy. The isolate was identified as Ochrobactrum sp. based on the morphological, nutritional and biochemical characteristics as well as 16S rRNA gene sequence analysis. A combination of chromatographic analyses, oxygen uptake assay and enzymatic studies confirmed the degradation of phenanthrene by the strain PWTJD via 2-hydroxy-1-Naphthoic Acid, salicylic Acid and catechol. The strain PWTJD could also utilize 2-hydroxy-1-Naphthoic Acid and salicylic Acid, while the former was metabolized by a ferric-dependent meta-cleavage dioxygenase. In the lower pathway, salicylic Acid was metabolized to catechol and was further degraded by catechol 2,3-dioxygenase to 2-hydroxymuconoaldehyde Acid, ultimately leading to tricarboxylic Acid cycle intermediates. This is the first report of the complete degradation of a polycyclic aromatic hydrocarbon molecule by Gram-negative Ochrobactrum sp. describing the involvement of the meta-cleavage pathway of 2-hydroxy-1-Naphthoic Acid in phenanthrene assimilation.

imprinted nanobead based disposable screen printed potentiometric sensor for highly sensitive detection of 2 Naphthoic Acid
Materials Letters, 2018Co-Authors: Rongning Liang, Xiaofeng Yang, Wei QinAbstract:Abstract Currently, potentiometric sensors based on various molecularly imprinted polymer (MIP) receptors have been successfully fabricated for detection of organic species. However, almost all of the previously developed potentiometric sensors based on MIPs are in traditional liquid-contact mode in which lower detection limits have been restricted by zero-current transmembrane ion fluxes. Herein, a screen-printed potentiometric sensor for determination of 2-Naphthoic Acid has been developed. It is based on the MIP nanobeads as the selective receptor and the electrochemically reduced graphene oxide film as the solid contact. Compared with the classical potentiometric sensor, the proposed sensor based on nonequilibrium sensing mechanism exhibits remarkably improved detection sensitivity for 2-Naphthoic Acid with a low detection limit of 6.9 × 10−11 M.
