研究了从咖啡种子中分离出的6株具有马铃薯风味的菌株。基因序列分析（rrs和rpoB）表明它们属于泛菌属。通过DNA-DNA杂交，分离物构成了一个基因组种，与96株代表肠杆菌种的菌株的亲缘性小于17%。多位点序列分析（gyrB、rpoB、atpD和infB基因）表明，这些分离物代表了Pantoea属的一个独立种。新种的营养多样性较差。该新种为Pantoea coffeiphila sp. nov.，其类型菌株为Ca04(T) (=CIP 110718（T)=DSM 28482(T)）。
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)).
