South African Journal of Animal Science, Volume: 44, Issue: 5, Pages: 12-16, Published: 2014

Agriculture is responsible for 5% to 10% of the global anthropogenic greenhouse gas (GHG) emissions. Livestock contribute about 65% of agricultural GHG and enteric fermentation accounts for 90% of this. The global warming potential of CH4 is known to

Molecular forms of adenosine deaminase in pleural effusions

Autor: S. M. Grobler, Jacobus P.J. Ungerer

Publikováno v: Enzyme. 40(1)

The molecular forms of adenosine deaminase (ADA) were studied in pleural effusions with high ADA activity. The molecular forms were separated by polyacrylamide gel electrophoresis (PAGE), and the molecular masses estimated by gel filtration. Effusion
