Sumario: | Strain 33A1-SZDP(T) was isolated from a small creek located in Puch, Austria. Strain SP-Ram-0.45-NSY-1(T) was obtained from a small pond located in Schönramer Moor, Germany. 16S rRNA gene sequence similarities between the type strain of Silvanigrella aquatica , currently the only member of the family Silvanigrellaceae , and strains 33A1-SZDP(T) and SP-Ram-0.45-NSY-1(T) of 94.1 and 99.1 %, respectively, suggested affiliation of the two strains with this family. Phylogenetic reconstructions with 16S rRNA gene sequences and phylogenomic analyses with amino acid sequences obtained from 103 single-copy genes suggested that the strains represent a new genus and a new species in the case of strain 33A1-SZDP(T) (=JCM 32978(T)=DSM 107810(T)), and a new species within the genus Silvanigrella in the case of strain SP-Ram-0.45-NSY-1(T) (=JCM 32975(T)=DSM 107809(T)). Cells of strain 33A1-SZDP(T) were motile, pleomorphic, purple-pigmented on agar plates, putatively due to violacein, and showed variable pigmentation in liquid media. They grew chemoorganotrophically and aerobically and tolerated salt concentrations up to 1.2 % NaCl (v/w). The genome size of strain 33A1-SZDP(T) was 3.4 Mbp and the G+C content was 32.2 mol%. For this new genus and new species, we propose the name Fluviispira multicolorata gen. nov., sp. nov. Cells of strain SP-Ram-0.45-NSY-1(T) were motile, pleomorphic, red-pigmented and grew chemoorganotrophically and aerobically. They tolerated salt concentrations up to 1.1 % NaCl (v/w). The genome size of strain SP-Ram-0.45-NSY-1(T) was 3.9 Mbp and the G+C content 29.3 mol%. For the new species within the genus Silvanigrella we propose the name Silvanigrella paludirubra sp. nov. |
