Fig. 3From: Horizontal acquisition of hydrogen conversion ability and other habitat adaptations in the Hydrogenovibrio strains SP-41 and XCL-2Expression of SP-41’s hydrogenase genes under different cultivation conditions. Relative expression of the hynL genes for the large subunit group 1 [NiFe]-hydrogenases in hydrogenase gene cluster I a and cluster II b, normalized to the housekeeping gene rpoD. The expression was analyzed for SP-41 grown in MJ medium for 8 h (light blue bars) and 24 h (dark blue bars), in MJ-T medium grown for 8 h (light orange bars) and 24 h (dark orange bars)Back to article page
