摘要
The mechanism of the inactivation of thermophiles using active oxygen species concerning the destruction of the spore coat of thermophiles is proposed. The dependences of the light emission intensity of the excited oxygen molecule, the decomposition rate of the dipicolinic acid, and the inactivation rate of the thermophile on the oxygen gas pressure have similar tendencies. The inactivation mechanism is the decomposition of the dipicolinic acid in the spore coat by the excited oxygen molecule. (C) 2013 The Japan Society of Applied Physics
