Abstract: 
A cream-white-pigmented, oxidase-negative bacterium (strain 2015-2462-01T), isolated from a drinking water system, was investigated in detail to determine its taxonomic position. Cells of the isolate were rod-shaped and stained Gram-negative. A comparison of the 16S rRNA gene sequence of strain 2015-2462-01T with sequences of the type strains of closely related species of the genus Serratia revealed highest similarity to Serratia fonticola (98.4 %), Serratia proteamaculans (97.8 %), Serratia liquefaciens and Serratia grimesii (both 97.7 %). 16S rRNA gene sequence similarities to all other Serratia species were below 97.4 %. Multilocus sequence analysis (MLSA) on the basis of concatenated partial gyrB, rpoB, infB and atpD gene sequences showed a clear distinction of strain 2015-2462-01T from the type strains of the closest related Serratia species. The fatty acid profile of the strain consisted of C16 : 1 ω7c, C16 : 0; C14 : 0 and C14 : 0 3-OH/iso-C16 : 1 I as major components. DNA-DNA hybridizations between 2015-2462-01T and S. fonticola ATCC 29844T resulted in a relatedness value of 27 % (reciprocal 20 %). This DNA-DNA hybridization result in combination with the MLSA results and the differential biochemical properties indicated that strain 2015-2462-01T represents a novel species of the genus Serratia, for which the name Serratia aquatilis sp. nov. is proposed. The type strain is 2015-2462-01T ( = LMG 29119T = CCM 8626T).
