Contributions of atmospheric CO and hydrogen uptake to microbial dynamics on recent Hawaiian volcanic deposit

Article Abstract:

Research reveals that atmospheric carbon dioxide and hydrogen are utilized by all microbes colonizing volcano deposits, except the most recent deposits, as carbon and energy sources. Data indicate that in situ uptake rates are comparable to those of matured continental systems and that carbon dioxide and hydrogen contribute 2 to 4% and 15 to 20% of total respiratory reducing equivalent flow, respectively.

Molecular analysis of carbon monoxide-oxidizing bacteria associated with recent Hawaiian volcanic deposits

Article Abstract:

The aerobic carbon monoxide oxidation takes place everywhere with a lot of activity is specified for the various aquatic and terrestrial systems. Finally, to sum it up the outcome shows that the carbon monoxide oxidizing practical group is related with the volcanic deposits of the Hawaiian Islands and has a lot of potential for expansion.

Uptake of carbon monoxide and hydrogen at environmentally relevant concentrations by myobacteria

Article Abstract:

Results of growth by several mycrobacteria, including M.smegmatis and M.tuberculosis H37Ra on gas phase CO at concentrations up 50 percent are presented. They suggest that CO utilization occurs commonly among slow growing mycrobacteria, with some exceptions.
