Because the nature of the main resource that limits bacterioplankton (e.g. organic carbon [C] or phosphorus [P]) has biogeochemical implications concerning organic C accumulation in freshwater ecosystems, empirical knowledge is needed concerning how bacteria respond to these two resources, available alone or together. We performed field experiments of resource manipulation (2×2 factorial design...

The use of capnography during general anesthesia has become not only state of the art but also a recommended standard of care. In intubated patients, measurements of partial pressure of carbon dioxide in exhaled pulmonary gases approximate partial pressure of carbon dioxide in arterial blood under stable conditions. End-tidal carbon dioxide measurement has allowed anesthetists to continuously f...

This study compared the growth and biomass production of Isochrysis galbana under hetero-, mixo-, and phototrophic conditions using different organic carbon sources. The growth of I. galbana was inhibited in heterotrophy but was enhanced in mixotrophy compared to that in phototrophy. Subsequently, the influences of organic carbon and environmental factors (light and salinity) on the growth of I...

The planktonic microbial communities of Lakes Hoare and Bonney were investigated during transition into winter. We hypothesized that the onset of darkness induces changes in the functional role of autotrophic and heterotrophic microplankton. Bacteria decreased in Lake Hoare during March-April, while in Lake Bonney bacterial abundances varied. Heterotrophic nanoflagellates (HNAN), phototrophic n...

Ecological aspects of coal combustion utilization of CO2 from flue gas Slovakia belongs to the group of twenty worst polluters throughout the world, releasing 10 12 tons of carbon dioxide per capita, whereas the worldwide average value is about 5 tons. It is known that the big electric and thermal power stations produce only 25 % of the overall production of carbon dioxide in Slovakia, whereas ...

The first proof that heterotrophic, non-photosynthetic bacteria can fix carbon dioxide was presented in 1935 by Wood and Werkman (15). This investigation introduced the first experimental evidence that carbon dioxide serves as a building material in synthetic reactions of all forms of life, whether simple or complex. The synthesis of citric acid from oxalacetate by avian tissue was shown by Kre...
