1900Jrnl. Chem. Soc. LXXVIII. ii. 678 The evolution of gas [from the yeast] is almost immediately arrested by the addition of sulphur, a fact which suggests that the ferments in question are closely related to philothion or hydrogenase. 1943Jrnl. Biol. Chem. CLI. 384 Hydrogenase is closely related to the nitrogen-fixing system in Azotobacter. 1965A. H. Rose Chem. Microbiol. vii. 142 There exists a close relationship between the ability of organisms..to fix nitrogen, and the presence in the organisms of the enzyme hydrogenase. 1966Frenkel & Cost in Florkin & Stotz Comprehensive Biochem. XIV. viii. 417 Hydrogenase activity can also be observed in certain algae which can carry out photoreduction of CO2 with molecular hydrogen. |
