متن کاملArchaea in biogeochemical cycles.
Archaea constitute a considerable fraction of the microbial biomass on Earth. Like Bacteria they have evolved a variety of energy metabolisms using organic and/or inorganic electron donors and acceptors, and many of them are able to fix carbon from inorganic sources. Archaea thus play crucial roles in the Earth's global geochemical cycles and influence greenhouse gas emissions. Methanogenesis a...

متن کاملPetri nets of groups in biogeochemical cycles
Petri nets concepts provide additional tool for the modeling of metabolic networks. Especially the concepts of siphon and trap are used to study the role of trios phosphate isomerase’s (TPI) in trypanosome brucei metabolism. In this paper we show that the marked graph for groups with generating set has subset of places whose input transitions is equal to the output transitions and both of them ...
متن کاملMicrobial regulation of global biogeochemical cycles
Global biogeochemical cycles of carbon and other nutrients are increasingly affected by human activities (Griggs et al., 2013). So far, modeling has been central for our understanding of how this will affect ecosystem functioning and the biogeochemical cycling of elements (Treseder et al., 2012). These models adopt a reductive approach built on the flow of elements between pools that are diffic...
