Abstract: | An orange-coloured myxobacterium, MNa11734T , was isolated from desert in Iran. MNa11734T had rod-shaped vegetative cells, moved by gliding and was bacteriolytic. No real fruiting body formation could be observed, but sporangioles were produced on water agar. The strain was mesophilic, strictly aerobic and chemoheterotrophic. 16S rRNA gene analyses revealed that MNa11734T belonged to the family Nannocystaceae, genus Nannocystis and was closely related to Nannocystis pusilla Na p29T (DSM 14622T ) and Nannocystis exedens Na e1T (DSM 71T ), with 97.8 and 97.6 % 16S rRNA gene sequence similarity, respectively. Laboratory-measured DNA–DNA hybridization showed only 9.5/15.7 % (reciprocal) similarity between the novel strain and N. pusilla Na p29T , and 14.1/20.4 % between the strain and N. exedens Na e1T , whereas DNA–DNA hybridization estimates derived from draft genome sequences were 21.8–23.0 % and 22.2–23.7 %, respectively, depending on the calculation method. The G+C content of DNA from Nannocystis konarekensis MNa11734T was 73.3 mol%, for N. pusilla Nap29T it was 71.8 mol% and for N. exedens Nae1T it was 72.2 mol%. The major fatty acids of the new strain were C16 : 1 (56.2 %), iso-C17 : 0 (14.4 %), C14 : 0 (8.2 %), C16 : 0 (6.6 %) and iso-C15 : 0 (5.9 %). Strain MNa11734T exhibited phylogenetic and physiological similarities to the two other species of Nannocystis, i.e. N. pusilla and N. exedens, but the differences were sufficient enough to represent a novel species, for which the name Nannocystis konarekensis sp. nov. is proposed. The type strain is MNa11734T (=DSM 104509T =NCCB 100618T ). |
