[Abstract] Streptomyces species produce spores, which, while not as robust as endospores of Bacillus or Clostridium species, are capable of surviving for months or even years (Hopwood, 2006). During this time these spores remain viable, surviving by slowly degrading internal stores of carbon compounds, such as the carbohydrate trehalose. To enable metabolism to continue they must have access to an electron acceptor that allows the removal of the reducing equivalents that accumulate through metabolic activity. The most commonly used acceptor is oxygen. We describe the quantitative measurement of oxygen respiration rates by developmentally arrested spores of the streptomycete Streptomyces coelicolor (Fischer et al., 2013).
[摘要] < em>链霉菌属</em>物种产生孢子,其不如芽孢杆菌属或梭状芽孢杆菌属物种的内生孢子那样坚固,能够存活数月或甚至数年 Hopwood,2006)。 在此期间,这些孢子保持存活,通过缓慢降解碳化合物(例如碳水化合物海藻糖)的内部储存而存活。 为了使代谢能够继续,它们必须获得电子受体,其允许去除通过代谢活性积聚的还原当量。 最常用的受主是氧。 我们描述了通过发育阻止的链霉菌链霉菌(Streptomyces coelicolo)孢子的氧呼吸速率的定量测量(Fischer等人,2013)。
