Model		7 GHz (CW) exposure at thermal levels to yeast and bacteria and analysis of cytotoxicity under different conditions of growth
Details		Yeast and bacterial suspensions were exposed to 7 GHz (CW) RF at thermal levels and analyzed for heating profile and effects on growth. The authors report more intensive microwave heating of yeast and bacterial with increasing concentration at the same irradiation dose. In one study, E coli B/r, E coli Bs-1 and Zygosaccharomyces bailii cells were exposed to high temperature (52 degrees C) at different rates (0.015, 0.25 and 1.50 degrees C per second) and in media with different salt concentrations, pH, and with or without chloramphenicol. The authors report different levels of heat sensitivity and cytotoxicity under these different conditions. A number of other Russian papers on thermal heating of bacteria were also published (Tsitologiia (2002) 44(5):450-4; Radiats Biol Radioecol. (2003) 43(4):400-3; Tsitologiia (2000) 42(9):891-5; Tsitologiia (1999) 41(7):605-9; Biofizika (1998) 43(3):516-21; Radiats Biol Radioecol (1998) 38(2):232-7; Tsitologiia (1998) 40(2-3):178-84; Radiats Biol Radioecol (1996) 36(5):671-5; Biofizika (1996) 41(3):636-41; Tsitologiia (1996) 38(12):1269-73; Radiats Biol Radioecol (1995) 35(1):47-52; Mikrobiologiia (1986) 55(2):278-81; Radiobiologiia (1976) 16(6):834-7. Several related papers looking at effects of ionizing radiation on bacteria grown under different conditions were also published in the Russian literature.
