The Physiology of Obligate Anaerobiosis

摘要: Publisher Summary The chapter discusses the physiology of obligate anaerobiosis. An anaerobe emerges as an organism that: (i) generates energy and synthesizes its substance without recourse to molecular oxygen; (ii) demonstrates a singular degree adverse oxygen-sensitivity, which renders it unable grow under atmosphere air. most oxygen sensitive organisms are generally spoken very strict, extreme, or fastidious anaerobes; this imprecise, but convenient, terminology serving distinguish them from more oxygen-tolerant, less exacting moderate anaerobes. Even assuming that anaerobes aerobes can be segregated on basis whether they contain singlet-oxygen-preventing superoxide dismutase (and even greater range must first examined prove point), one would still have explain tremendous spectrum sensitivity is found amongst dismutase-less species. strictly anaerobic bacteria has paradoxically been both feature guaranteed their continuing fascination for microbiologists major deterrent study.
