    • ‘The use of physical or chemical means to destroy all microbial life including highly resistant bacterial endospores.’
    • ‘We have directly visualized high-resolution native structures of bacterial endospores, including the exosporium and spore coats of four Bacillus species in air and water environments.’
    • ‘Endospores may be located in the middle of the cells, at the end, or between the end and the middle of the cells.’
    • ‘Detecting bacterial endospores is a critical challenge to chemistry, since a number of serious diseases and health problems are caused by them.’
    1. 1.1 The inner layer of the membrane or wall of some spores and pollen grains.
      • ‘It is released from the outer cell wall of endospores at sporulation.’
