[f. the name of John Tyndall, an English physicist (1820–93); cf. PASTEURIZATION.] A method of sterilization in which time is allowed between repeated heatings for bacteria to develop; fractional or intermittent sterilization. So Tyndallize v. trans. to sterilize by this process (Webster, 1911).
1897. W. H. Park & J. Wright, trans. Wüurtz’ & Lermoyez’ Annales des maladies de l’oreille (1893), in Trans. Amer. Laryngological Assoc., 171. We have used the mucus thus obtained, sometimes in its natural state, sometimes after having been sterilized by the procedure of Tyndall. Tyndallization in no way changes its characters.
