说明

General description

m-Xylene is an isomeric form of xylene. Experimental values of density (ρ) and speed of sound (u) of its binary mixtures with diethyl carbonate (DEC) have been evaluated over the temperature range of 298.15-323.15K and at 0.1MPa atmospheric pressure.

Application

m-Xylene may be used in the synthesis of isophthalic acid and phthalaldehyde.

A sulfate-reducing consortium maintained for several years in the laboratory with m-xylene as sole source of carbon and energy was characterized by terminal restriction fragment length polymorphism (T-RFLP) fingerprinting of PCR-amplified 16S rRNA genes and stable isotope probing of proteins

The regulatory logic of m-xylene biodegradation by Pseudomonas putida mt-2 exposed by dynamic modelling of the principal node Ps/Pr of the TOL plasmid.

Environmental microbiology, 12(6), 1705-1718 (2010-06-18)

The structure of the extant transcriptional control network of the TOL plasmid pWW0 born by Pseudomonas putida mt-2 for biodegradation of m-xylene is far more complex than one would consider necessary from a mere engineering point of view. In order
