Luteibacter flocculans sp. nov., Isolated from a Eutrophic Pond and Isolation and Characterization of Luteibacter Phage vB_LflM-Pluto

Abstract

Luteibacter is a genus of the Rhodanobacteraceae family. The present study describes a novel species within the genus Luteibacter (EIF3T). The strain was analyzed genomically, morphologically and physiologically. Average nucleotide identity analysis revealed that it is a new species of Luteibacter. In silico analysis indicated two putative prophages (one incomplete, one intact). EIF3T cells form an elliptical morphotype with an average length of 2.0 µm and width of 0.7 µm and multiple flagella at one end. The bacterial strain is an aerobic Gram-negative with optimal growth at 30 °C. EIF3T is resistant towards erythromycin, tetracycline and vancomycin. We propose the name Luteibacter flocculans sp. nov. with EIF3T (=DSM 112537T = LMG 32416T) as type strain. Further, we describe the first known Luteibacter-associated bacteriophage called vB_LflM-Pluto.
