    • ‘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.’
    • ‘Detecting bacterial endospores is a critical challenge to chemistry, since a number of serious diseases and health problems are caused by them.’
    • ‘Only a few genera of bacteria such as Bacillus and Clostridium are capable of forming endospores.’
    • ‘Endospores may be located in the middle of the cells, at the end, or between the end and the middle of the cells.’
    1. 1.1The inner layer of the membrane or wall of some spores and pollen grains.
