The final two taxonomic ranks, genus and species, which are are the most specific of all the ranks, are used for an animal's scientific name.
Illumina sequencing showed that Thiobacillus became the dominant genus in the final enrichment culture, in which autotrophic denitrification rate was 21 mg N2-N (g VS d)−1.
The final pan-genome for the genus consisted of 6122 ORFs (Additional file 1).
Using this compilation, we calculated the number of target species that needed to be sampled for each genus to obtain a final dataset of ~5,000 species (~30% sampling of total diversity) in which sampling of species in each genus is proportional to their described diversity.
Different taxonomic resolution levels were tested and a final tool is proposed based on a genus level identification of chironomid taxa and a classification system based on sensitive/tolerant taxa abundances.
The only obligatory final host is an eel of the genus Anguilla[ 17].
Preliminary analyses confirmed with complete support that all new sequences corresponded to Pseudotrichonympha, and a more detailed analysis focused exclusively on sequences from this genus and outgroups, resulting in a final alignment of 28 taxa and 1,388 positions.
An extensive investigation of cytb in this genus would be necessary to draw final conclusions and to disentangle authentic mtDNA sequences and numts.
Because of the small number of these alternative nitrogenases, sequences from multiple species within a genus were retained for analysis for a final set of 15 alternative nitrogenases.
The final trees were rooted using four species of the genus Petrobia as outgroup.
