Enzymatic synthesis of fatty esters in 5-caffeoyl quinic acid

Bernard Guyot; Dominique Gueule; Michel Pina; Jean Graille; Vincent Farines; Marie Farines

The fatty esters of 5-caffeoyl quinic acid were synthesized by direct esterification biocatalysed by an immobilised lipase obtained from Candida antarctica. Esterification yields (from 40 to 75%) depended on the carbon chain length of the fatty alcohols and whether or not solvent (2-methyl 2-butanol) was present in the reaction medium.

Pantoea coffeiphila sp. nov., cause of the ‘potato taste’ of Arabica coffee from the African Great Lakes region

Dominique Gueule; Gérard Fourny; Elisabeth Ageron; Anne Le Flèche-Matéos; Mathias Vandenbogaert; Patrick A. D. Grimont; Christian Cilas

Six isolates recovered from coffee seeds giving off a potato-like flavour were studied. Gene sequencing (rrs and rpoB) showed they belong to the genus Pantoea. By DNA-DNA hybridization, the isolates constituted a genomic species with less than 17% relatedness to 96 strains representing enterobacterial species. Multilocus sequence analysis (gyrB, rpoB, atpD and infB genes) showed the isolates to represent a discrete species of the genus Pantoea. Nutritional versatility of the novel species was poor. The novel species is proposed as Pantoea coffeiphila sp.nov. and its type strain is Ca04(T) ( =CIP 110718(T) =DSM 28482(T)).
