Gram-positive In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. Gram-positive bact ...

. The species was named by the researchers, "in honor of the late Indra M. Mathrani, who contributed greatly to our understanding of thermophilic anaerobes from hot springs during his short career." A subspecies, ''T. mathranii'' subsp. ''alimentarius'' was found in canned food.Jean-Philippe Carlier, Isabelle Bonne, Marie Bedora-Faure.
