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

摘要

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 Ca04T (5CIP 110718T5DSM 28482T). (Résumé d'auteur)
