TEMPERATURE ADAPTATIONS IN EUGLENA 91 data taken together suggest that acetate-grown Euylena may consume oxygen via two principal routes: one as terminal electron acceptor in respiration, and the other in some non-respiratory and non-energy-yielding reaction(s) associated with growth on acetate. Grozi'th rate and synthetic rate Schaechter et al. (1958) showed in the bacterium Salmonella typhiinurmni that mass and RNA levels were a positive exponential function of the growth rate but quite independent of temperature between 25° and 37° C, when the growth rate was varied by culture on different carbon sources. Since temperature affects growth rate as well as other physiological rates in Euglena with only acetate as carbon and energy source, it was of interest to know whether the observed effects were due primarily to temperature or indirectly to altered growth rates. The present data have been examined to determine whether the biochemical and physiological profiles of Euglena conform to some general pattern of the sort described by Schaechter et al. No such pattern was found. Figure 6 shows mass and RNA as a function HI D < 4 3. Mass RNA .01 02 03 04 05 .06 GROWTH RATE 07 FIGURE 6. Log plot of mass and RNA content of E. gracilis strain Z (filled figures) and var. bacillaris (open figures) as a function of growth rate. Ordinate values for RNA are to be multiplied by 10 and those for mass by 1000 to give the amount in.
