| Method |
"Oxygen evolution in whole cells (10 µg chlorophyll) was measured in BG-11 media in the presence of 1 mM artificial electron acceptors DCBQ [2,6-dichloro-p-benzoquinone] or DMBQ [2,5-di-methyl-p-benzoquinone] (Eastman Kodak). This electron acceptor concentration yielded maximal rates of oxygen evolution for all four strains. Attempts to improve the assay including the addition of 1 or 5 mM K3Fe(CN) 6 as a terminal electron acceptor in the presence of either DCBQ or DMBQ did not enhance oxygen evolution rates." |
| Comments |
Value taken for the WT Berkeley strain of PCC 7942 from table III. Range is standard error of replicated measurements. |
