Harlan surface (1), (2), Harlan whole body homogenate, and Colorado surface isolates were determined to be facultative anaerobes, and the isolates from the whole body homogenate and surface swab from the Colorado strain were obligate aerobes. The isolates were tested for the presence of the enzymes catalase, oxidase, gelatinase, coagulase, urease, and amylase.
OA = obligate aerobe; FAN = facultative anaerobe; ND = not done; GH = gamma hemolysis; AH = alpha hemolysis; NA = unable to determine because of lack of growth.
Methanogens are obligate anaerobes; occupying deeper and wetter soil horizons, whereas the methane oxidizers (obligate aerobes) occupy surface, aerobic horizons.
