The Silvanigrellaceae are the only family of the order Silvanigrellales, of the class Oligoflexia, of the phylum Pseudomonadota. [1] [2] This family currently harbors the two genera Silvanigrella [1] and Fluviispira [3]

The Thermoprotei is a class of the Thermoproteota.
Desulfovibrionales are a taxonomic order of bacteria belonging to the phylum Thermodesulfobacteriota, with four families. They are Gram-negative. The majority are sulfate-reducing, with the exception of Lawsonia and Bilophila. All members of this order are obligately anaerobic. Most species are mesophilic, but some are moderate thermophiles.
Desulfovibrionaceae is a family of bacteria belonging to the phylum Thermodesulfobacteriota.
The Myxococcota are a phylum of bacteria known as the fruiting gliding bacteria. All species of this group are Gram-negative. They are predominantly aerobic genera that release myxospores in unfavorable environments.
The Desulfurococcales are an order of the Thermoprotei, part of the kingdom Archaea. The order encompasses a number of genera which are all thermophilic, autotrophs which utilise chemical energy, typically by reducing sulfur compounds using hydrogen.
In taxonomy, the Methanococcales are an order of the Methanococci.
The Selenomonadales are an order of bacteria within the class Negativicutes; unlike most other members of Bacillota, they are Gram-negative. The phylogeny of this order was initially determined by 16S rRNA comparisons. More recently, molecular markers in the form of conserved signature indels (CSIs) have been found specific for all Selenomonadales species. On the basis of these markers, the Selenomonadales are inclusive of two distinct families, and are no longer the sole order within the Negativicutes. Several CSIs have also been found specific for both families, Sporomusaceae and Selenomonadceae. Samples of bacterial strains within this order have been isolated from the root canals of healthy human teeth.
Desulfonatronum is a Gram-negative and extremely alkaliphilic bacteria genus from the family of Desulfovibrionaceae.
The Silvanigrellales are an order of the phylum Bdellovibrionota. They include currently only the single family Silvanigrellaceae.
Silvanigrella aquatica is a bacterial species of the phylum Bdellovibrionota. The type strain was isolated from the small lake Nonnenmattweiher located in the Southern Black Forest in Germany. This species is currently the only species in the genus Silvanigrella, which is the only genus in the family Silvanigrellaceae, which is the only family in the order Silvanigrellales. The order Silvanigrellales is one of only two orders in the class Oligoflexia. The type strain MWH-Nonnen-W8red is remarkable due to its low GC content, its pigmentation and its plastic morphology. Of further interest is the relative close relationship of S. aquatica to "Spirobacillus cienkowskii" known as pathogens of daphnids (Daphnia), which are commonly called water fleas. However, S. aquatica is assumed to be a non-pathogenic free-living species. The genome of the type strain was sequenced,
