Microbial distribution in soils: physics and scaling (2008, background): “In soil, extracellular enzyme producers compete with microbes that do not, but that consume the products, called ‘‘cheaters’’ (Allison, 2005).”
Microbial control over carbon cycling in soil (2012, background): “The products of exoenzyme breakdown become available to other organisms including other microbes, so called “cheaters” (Allison, 2005) or “opportunists” (Moorhead and Sinsabaugh, 2006), and to plant roots (Schimel and Bennett, 2004).”
Acquisition of phosphorus and other poorly mobile nutrients by roots. Where do plant nutrition models fail? (2011, unknown): “The models of Allison (2005) and Schimel andWeintraub (2003) could also be considered as a first step to take into account the production of exoenzymes by rhizosphere microorganisms as related to rhizodeposition of carbon-rich substrates.”
Linkages between extracellular enzyme activities and the carbon and nitrogen content of grassland soils (2016, background): “In addition, increased stratification of SOM can lead to higher spatial heterogeneity of the soil matrix, which in turn can be associated with a larger number of niches available to microbial enzyme foraging (Allison, 2005).”
Extracellular enzymes in terrestrial, freshwater, and marine environments: perspectives on system variability and common research needs (2013, background): “Spatial heterogeneity may also interact with enzyme persistence, with high persistence favoring fast-growing microorganisms that may not produce enzymes (Allison 2005), leading to another unstable system.”
The role of terrestrially derived organic carbon in the coastal ocean: A changing paradigm and the priming effect (2011, background): “As extracellular enzymes function outside the cell, the reaction products may diffuse away from the enzyme-secreting microbe (33, 34).”
Microbial communities and their relevance for ecosystem models: Decomposition as a case study (2010, background): “For example, 'cheater' microbes, which do not produce their own enzymes, but instead intercept the products produced by extracellular enzymes of other microorganisms, could suppress proliferation of enzyme-producers (Allison, 2005).”
Regulation of extracellular protease activity in soil in response to different sources and concentrations of nitrogen and carbon. (2008, background): “Several authors have presented conceptual models using enzyme activity to describe the acquisition of C and N by microbes (Sinsabaugh and Moorhead, 1994; Schimel and Weintraub, 2003; Allison, 2005).”
High dissolved extracellular enzymatic activity in the deep central Atlantic ocean (2010, background): “Moreover, Allison (2005) argued that microbes releasing EE have a competitive advantage over other microbes in environments with low rates of enzyme diffusion, such as sediments or particles.”
