Tf. Brocklehurst et al., AN APPARATUS FOR STUDYING THE EFFECT OF TRANSIENT TEMPERATURE ON GROWTH OF BACTERIA IN A GEL MATRIX, Food microbiology, 13(2), 1996, pp. 109-114
Apparatus was constructed to subject colonies of bacteria, formed from
single cells immobilized in solidified culture media contained betwee
n sheets of polymer, film to time-varying temperatures in the range 2-
80 degrees C with rates of change of 1 degrees C s(-1). Results for th
e growth of Salmonella typhimurium LT2 in medium solidified with gelat
in under sinusoidally-varying temperatures between 12 and 22 degrees C
and of period 12 or 22 min are presented and were predictable by time
-temperature integration using isothermal growth rates. (C) 1996 Acade
