Mineralization of 4-Chlorodibenzofuran by a Consortium Consisting of Sphingomonas sp. Strain RW1 and Burkholderia sp. Strain JWS.

The dibenzofuran-degrading bacterium Sphingomonas sp. strain RW1 (R.-M.

Biochemical and genetic characterization of a gentisate 1, 2-dioxygenase from Sphingomonas sp. strain RW5.

A 4,103-bp long DNA fragment containing the structural gene of a gentisate 1,2-dioxygenase (EC 1.13.11.

Microbial reduction of aromatic carboxylic acids.

Several benzoic, cinnamic and phenylacetic acid derivatives were screened with 20 micro-organisms, mainly fungi, for the reduction of their carboxylic function. For all organisms several compounds were reduced in fairly good yields up to 80% to the corresponding alcohol. No general rule could be established, concerning the substitution pattern, as to which compounds were transformed to the alcohol.

Investigation of the Alkaloid Pattern of Datura innoxia Plants by Capillary Gas-Liquid-Chromatography-Mass Spectrometry.

The alkaloid composition of DATURA INNOXIA plants was analysed by quartz capillary GLC and GLC-MS. Significant differences were found in the alkaloid pattern of the respective plant organs even between different aerial parts. More than 30 alkaloids could be identified.
