Enhancing hydrogen‐dependent growth of and carbon dioxide fixation by Clostridium ljungdahlii through nitrate supplementation

Formic Acid Formation by Clostridium ljungdahlii at Elevated Pressures of Carbon Dioxide and Hydrogen

Low productivities of bioprocesses using gaseous carbon and energy sources are usually caused by the low solubility of those gases (e.g., H2 and CO). It has been suggested that increasing the partial pressure of those gases will result in higher dissolved concentrations and should, therefore, be helpful to overcome this obstacle. Investigations of the late 1980s with mixtures of hydrogen and ca...

Carbon Dioxide Fixation by Extracts of Streptococcus

sence of exogenously added glutamate and pyridoxal-5'-phosphate and produced radioactive aspartate in the presence of these components. Reduced nicotinamide adenine dinucleotide or reduced nicotinamide adenine dinucleotide phosphate could not be substituted for adenosine triphosphate (ATP); phosphoenolpyruvate even in the presence of nucleoside diphosphates could not replace pyruvate plus ATP; ...

Carbon Dioxide Fixation by Detached Cereal Caryopses1

Immature detached cereal caryopses from barley (Hordeum vulgare L. var distichum cv Midas) and wheat (Triticum aestivum L. cv Sicco) were shown to be capable of fixing externally supplied"'CO2 in the light or dark. Green cross cells and the testa contained the majority of the 14Clabeled material. Some "4C-labeled material was also found in the outer, or transparent, layer and in the endosperm/e...

Carbon dioxide fixation by detached cereal caryopses.

Immature detached cereal caryopses from barley (Hordeum vulgare L. var distichum cv Midas) and wheat (Triticum aestivum L. cv Sicco) were shown to be capable of fixing externally supplied (14)CO(2) in the light or dark. Green cross cells and the testa contained the majority of the (14)C-labeled material. Some (14)C-labeled material was also found in the outer, or transparent, layer and in the e...
