TL;DR: The Pseudomonas fluorescens N3 strain was isolated from soil for its ability to utilize naphthalene as a carbon source as discussed by the authors, and the strain transforms 2,3-dimethyl-, 2-methoxy-, 1-and 2-ethylnaphthalenes to the corresponding salicylic acids competitively with chemical synthesis.
Abstract: The Pseudomonas fluorescens N3 was isolated from soil for its ability to utilize naphthalene as a carbon source. The strain transforms 2,3-dimethyl-, 2-methoxy-, 1- and 2-ethylnaphthalenes to the corresponding salicylic acids competitively with chemical synthesis. The identification of 2-hydroxy-2-carboxy-7-ethylchromane by biotransformation of 2-ethylnaphthalene, contributes to elucidating the steps involved in the catabolic pathways of naphthalenes to salicylaldehydes.

TL;DR: In this article, the complex [Co(P(CH{sub 3} ),sub 3 },sub 4] was found to mediate the Reformatsky-type reaction of halogenated esters, lactones, or amides with carbonyl compounds (ketones, aldehydes).
Abstract: The complex, [Co(P(CH{sub 3}){sub 3}){sub 4}], is found to mediate the Reformatsky-type reaction of halogenated esters, lactones, or amides with carbonyl compounds (ketones, aldehydes). The products of these reactions are alcohols. 15 refs., 1 tab.

TL;DR: Callus cultures were established from hypocotyl, root and leaf explants of Solanum malacoxylon using Murashige and Skoog medium as well as Gamborg's B5 medium and feeding experiments with vitamin D3 were scarcely effective in promoting the production of Vitamin D3 hydroxylated metabolites.
Abstract: Callus cultures were established from hypocotyl, root and leaf explants of Solanum malacoxylon. The growth rate of calli was evaluated on Murashige and Skoog medium as well as Gamborg's B5 medium. Sterols were isolated from calli grown on both media however the B5 proved to be more effective in promoting the production of these metabolites. No calcitriol was found in the cultures. Feeding experiments with vitamin D3 were scarcely effective in promoting the production of vitamin D3 hydroxylated metabolites.
