Type strain
AP-Melu-1000-B4 = DSM 103591 = CIP 111329

Polynucleobacter necessarius subsp. asymbioticus, Polynucleobacter sp. AP-Melu-1000-B4

The type strain was isolated from the mountain lake (1,710 meters) Lac de Melu located in the Restonica Valley on the Mediterranean island Corsica, France near to the commune of Corte. The type strain of P. meluiroseus is remarkable because of its unusual pigmentation compared to other Polynucleobacter strains, as well as due to the presence of a Proteorhodopsin gene in the genome of the strain. Furthermore, the 16S rRNA gene of the type strain contains an unusual indel previously only known from uncultured Polynucleobacter strains detected by cultivation-independent methods in mountain lakes located in the Pyrenees. The type strain dwells as a free-living, planktonic bacterium in the water column of the lake, thus is part of freshwater bacterioplankton. The complete genome sequence of the type strain was determined.[3]
