Carbon Monoxide Metabolism in Roadside Soils

Dark metabolism of carbon monoxide in lettuce leaf discs.

In the dark, leaf tissue of crisphead lettuce (Lactuca sativa L.) metabolized (14)CO to (14)CO(2) and acid-stable products. Tissue incubated at 2.5 degrees C for 3.5 hours and 48 hours converted about 1% and 17%, respectively, of the applied (14)CO to (14)CO(2), and incorporated about 0.04% and 0.6% of the (14)C in acid-stable products. Examination of soluble acid-stable products from (14)CO an...

Effect of carbon monoxide on protein metabolism in mouse brain.

Carbon monoxide metabolism of the methylotrophic acidogen Butyribacterium methylotrophicum.

The Marburg strain of Butyribacterium methylotrophicum did not grow on CO alone but did consume CO during growth on a variety of substrates in the presence of a 100% CO gas phase. We selected a strain (the CO strain) that grew vigorously on CO alone. The ability of the CO strain to grow on CO was stable through multiple transfers in the absence of CO. CO dehydrogenase activity was lower in the ...

Biological signaling by carbon monoxide and carbon monoxide-releasing molecules.

Carbon monoxide (CO) is continuously produced in mammalian cells during the degradation of heme. It is a stable gaseous molecule that reacts selectively with transition metals in a specific redox state, and these characteristics restrict the interaction of CO with defined biological targets that transduce its signaling activity. Because of the high affinity of CO for ferrous heme, these targets...

Victim of carbon monoxide poisoning identified by carbon monoxide oximetry.

BACKGROUND Carbon monoxide (CO) is known as a leading cause of unintentional poisoning death in many countries. Diagnosis is usually made by measuring carboxyhemoglobin (COHb), but due to the non-specific symptoms, the crucial step is considering CO poisoning. A possible solution might be screening emergency department (ED) patients. A cutaneous sensor that measures oxygen and CO saturation sim...
