Dehydrogenation of Venus

Nature, 1970
VENERA 4, 5 and 6 indicate that the surface layers and atmosphere of Venus are considerably dryer than corresponding regions on Earth. The water content of the atmosphere is in the region of 0.1 to 1 per cent of the total atmospheric gases by volume1, and at the Venus surface temperatures of about 700 K this is very dry indeed.

Microbial dehydrogenation of tomatidine

Journal of Steroid Biochemistry, 1972
Abstract Tomatidine (tomatanin-3β-ol) was dehydrogenated by Nocardia restrictus to tamatanin-3-one, 1-tomatenin-3-one, 4-tomatenin-3-one and 1,4-tomatidien-3-one. No degradation of 1,4-tomatadien-3-one by Nocardia restrictus could be achieved.

Catalytic Dehydrogenation of Coal

Science, 1962
Coals were refluxed with palladium, ruthenium, and rhodium catalysts in high-boiling aromatic and heteroaromatic solvents. As much as 53 percent of the hydrogen in one coal was evolved as hydrogen gas. The yield of hydrogen varied with the rank of the coal and the nature of the solvent but was little influenced by the metal or catalyst support.

Substrate Dehydrogenation by Flavoproteins

Accounts of Chemical Research, 2001
Enzymes with tightly bound FMN or FAD as cofactor catalyze the oxidation of a wide range of substrates. The chemical versatility of the isoalloxazine ring provides these enzymes with a range of potential mechanisms. Recent progress in elucidating the mechanisms of oxidation of organic substrates by flavoenzymes is described, focusing on the oxidation ...
