Cross Index Ruminococcus
SuperSet Prokaryote, Eubacteria Gram Positive Cocci
Compare aerobes: Deinobacter grandis Deinococcus, Marinococcus, Micrococcus, Planococcus , Salinicoccus roseus

facultative anaerobes: Aerococcus viridans, Enterococcus, Gemella haemolysans, Lactococcus Leuconostoc, Melissococcus pluton, Pediococcus, Saccharococcus thermophilus, Staphylococcus, Stomatococcus mucilaginsos, Streptococcus, Trichococcus flocculiformis, Vagococcus


anaerobes Coprococcus, Peptococcus niger , Peptostreptococcus, Ruminococcus, Sarcina


Catalase positive:Deinococcus, Micrococcus, Planococcus, Staphylococcus,, Stomatococcus mucilaginsosus

Contrast Micrococcaceae are not a coherent group. Micrococcus is closely related to Arthrobacter , Planococcus is related to Bacilluss, while the radioresistant cocci called Deinococcus have atypical Gram positive cell walls

Growth Parameters Ruminococcus
PHYSIOLOGICAL  
Tropism chemoorganotrophic
Oxygen strictly anaerobic fermentative type of catabolism.
pH  
Temperature The optimum temperature fro growth is 37-42 C
Requirements  
Products Carbohydrates are fermentable substrates with the formation of acetate, succinate, lactate, ethanol, carbon dioxide and hydrogen. Amino acids and peptides are not fermented., nitrate is not reduced and ammonia is not produced from amino acids or peptides. Butyrate is not a fermentable product indole is not produced
Enzymes Catalase negative
