The section of the anaerobically cultured cells shows abundant and distinct chromatophores (C). Magnification as indicated for Fig. 6. Figs. 5 and 6. Sections of cells cultured for 66 hr. aerobically in the dark at 30° (cf. Fig. 9, ref. [31]). The cultures were gassed with 5^0 CO2 in air; the gassing rate was somewhat slower than indicated in the text and synthesis of a small amount of chlorophyll had taken place. A few scattered chromatophores (C) are apparent in some of the cells. A lamellar system (L) of unknown composition and function (cf. Figs. 21-25, ref. [3]) also can be Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original IUB/IUBS International Symposium (1st : 1960 : Stockholm); International Union of Biochemistry; International Union of Biological Sciences; Goodwin, T.
