text: # Advenella
  
  Advenella is a genus in the phylum Pseudomonadota (Bacteria). The two members of the genus Tetrathiobacter were transferred to this genus, namely Tetrathiobacter kashmirensis and Tetrathiobacter mimigardefordensis.
  
  ## Etymology
  
  The name Advenella derives from: Latin advena, a stranger, a foreigner; and ella, a diminutive; Advenella, then, means the little stranger, referring to the fact that the source of these unusual organisms is unknown.
