Corrosion Behavior and Inhibition

The physiological and morphological homogeneity of this group of bacteria is in conformity with a relatively narrow range of DNA base ratios and is in marked contrast to the diversity of nomenclature that has been applied to them. They are Gram-positive cocci with a strong tendency toward tetrad formation. They produce little or no anaerobic growth in shake cultures yet lack a porphyrin respiratory system and produce hydrogen peroxide which restricts their aerobic growth. Their DNA has a base ratio of 37-41% GC. They are variously known as Gaffkya homari, Pediococcus homari, or Aerococcus viridans. Their correct name must await action of the Judicial Commission regarding rejection of the generic name Gaffkya.
