Description of the organim. The coccus Micrococcus 8odonensis, nov. sp., has the following characteristics: Spheres: 0.8-1.5 microns; occurring singly, in pairs, and in groups of four. Nonmotile, nonsporeforming, and gram positive. Gelatin stab: No liquefaction. Agar slant: Abundant, yellow, shiny, butyrous. Broth: Turbid with sediment. Indole not formed. Nitrates not reduced. Hydrogen sulfide (lead acetate agar) not formed. Starch not hydrolyzed. No change in brom cresol purple milk. Growth in Koser's citrate broth when biotin added. No gas and acid from glucose, lactose, sucrose, maltose, mannitol. Aerobic. Optimal temperature, 35 C. Source: Fresh water lake. Nutritional requirements. The minimal nutritional requirements of Micrococcus sodonensis are presented in table 1. Growth was not further enhanced by the addition of a tryptic digest of casein or yeast autolysate. The coccus grew in
