"Pseudomonas luteola" is a Gram-negative, motile aerobe. Oxidase test is used to determine whether a bacterium is an aerobe or anaerobe. The microbe is strictly aerobe (no reduction of nitrate) and oxidase-positive. "Lysinibacillus fusiformis" tests positive for oxidase and is an obligate aerobe. "Moraxella bovis" is a Gram-negative rod-shaped aerobe. An obligate aerobe is an organism that requires oxygen to grow. It is a Gram-negative, rod-shaped aerobe, with type strain T-27 (=JCM 11422 =DSM 14586). The Aerobe 100 was essentially shortened Aerobee 150 with an AJ11 engine. An obligate aerobe, "A. coralicida" obtains its nourishment chemoheterotrophically. Since the organism is a strict aerobe, it used oxygen as a terminal electron acceptor. Leptospira interrogans is a Gram negative, obligate aerobe spirochete, with periplasmic flagella. Leptospira kirschneri is a Gram negative, obligate aerobe species of spirochete bacteria. Nitrosomonas marina is an ammonia-oxidizing, aerobe, gram-negative bacterium from the genus of "Nitrosomonas". In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment.
