Changes in distribution of intercalated-membrane particles of the outer alveolar membrane during low-temperature acclimation. The 39 ℃-grown culture (thermotolerant T. pyrifomis NT-1) was shifted down to 15 ℃ over a 30-min period and continued to grow at this low temperature. Samples were taken at indicated time intervals for freeze-fracture electron microscopy. a) 39 ℃ (before shift to 15 ℃); b) 0 h; c) 6 h; d) 11 h after shift. Data from Nozawa and Kasai (1978).18)
