Effects of various concentrations of carbonyl cyanide m-chlorophenyl hydrazone (CCCP) (a) and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) (b) on bidirectional hydrogenase of Aphanothece halophytica after 2 hours of treatment under illumination. 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.
