Effects of the Photosystem II Inhibitors CCCP and DCMU on Hydrogen Production by the Unicellular Halotolerant Cyanobacterium Aphanothece halophytica

Figure 2

Effects of various concentrations of carbonyl cyanide m-chlorophenyl hydrazone (CCCP) and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) on H2 production rate by Aphanothece halophytica after 2 hours of incubation under the light (a, c) and under darkness (b, d). Data are means ± SD (n = 3). Different letters above columns indicate a significant difference according to Duncan’s multiple range test at p < 0.05.
