Mycobacterium tuberculosis has been found to exhibit autolysis and spontaneous secondary growth in modified Sauton medium. The phenomenon is a function of high glycerol concentration of the medium and limitation of air in test tubes. It is not a function of depletion of nutrients and is probably not a manifestation of lysogeny or spheroplast formation. The cycle of growth, autolysis, and secondary growth is related to development of lethal conditions during a period of severe oxygen limitation followed by a metabolic change associated with slower depletion of glycerol.
已发现结核分枝杆菌在改良的苏通培养基中会出现自溶和自发二次生长现象。该现象是培养基中甘油浓度过高以及试管内空气受限的结果。它并非营养物质耗尽所致,可能也不是溶原性或原生质球形成的表现。生长、自溶和二次生长的循环与在严重氧气受限期间致死条件的发展有关,随后是与甘油消耗减缓相关的代谢变化。
