| Method |
From electron micrographs of chromatophores from Rhodopseudomonas spaeroides the estimated bacteriochlorophyll per chromatophore was estimated. |
| Comments |
The chromatophore count, shown graphically in Fig. 1 gives a mean ratio of 4700+-1300 bacteriochlorophyll molecules per vesicle. This value compares favourably with a theoretical estimate of 3600-18 000 bacteriochlorophyll per vesicle based on spectroscopic observations of the chromatophore carotenoid shift [7]. |
