Microbial community utilization of added carbon substrates in response to long-term carbon input manipulation (2006, methodology): “This method does not account for metabolite production or for biomass that is consumed by grazers (Frey et al., 2001).”
Do growth yield efficiencies differ between soil microbial communities differing in fungal : bacterial ratios? reality check and methodological issues (2006, methodology): “Other researchers have measured total C mineralization of added glucose to determine microbial growth yield efficiencies (e.g. Bremer and Kuikman, 1994; Frey et al., 2001).”
Effect of temperature on metabolic activity of intact microbial communities: Evidence for altered metabolic pathway activity but not for increased maintenance respiration and reduced carbon use efficiency (2011, background): “Additionally, CUE is affected by protozoa grazing (Frey et al., 2001), soilmoisture content (Herron et al., 2009), glucose addition (Bremer and Kuikman, 1994; Shen and Bartha, 1996), and oxygen concentration (Parsons and Smith, 1989).”
Carbon use efficiency of microbial communities: stoichiometry, methodology and modelling. (2013, background): “Other limitations of this approach that tend to inflate CUE have been extensively discussed (e.g. del Giorgio & Cole 1998; Frey et al. 2001; Herron et al. 2009).”
Accelerated microbial turnover but constant growth efficiency with warming in soil (2014, unknown): “RR! = RR − RR! = RR 1− 1−MMMMMM = RR ∗MMMMMM (10) 120 And turnover (d) is calculated as flux of C out of MBC divided by MBC: 121 ττ = !! !"# = !∗!"# !"# (11) 122”
Microbial carbon use efficiency: accounting for population, community, and ecosystem-scale controls over the fate of metabolized organic matter (2016, methodology): “Biosynthesis is the anabolic process of generating microbial biomass from PreC a Frey et al.

Altered patterns of soil carbon substrate usage and heterotrophic respiration in a pine forest with elevated CO2 and N fertilization (2008, background): “Because the efficiency with which microorganisms use C substrates varies greatly (del Giorgio & Cole, 1998; Frey et al., 2001; Thiet et al., 2006), we would expect shifting levels of activity among microbial groupings to result in altered microbial growth efficiency as well.”
Ecoenzymatic Stoichiometry and Ecological Theory (2012, background): “Most of these estimates are in the range of 0.50–0.60 (Frey et al. 2001, Manzoni et al. 2012).”
Soil protistology rebooted: 30 fundamental questions to start with (2017, unknown): “The main focus in earlier studies was, however, mainly on nitrogen cycling, and the importance of protists for cycling of other elements such as carbon and phosphorus has been relatively neglected, with few exceptions (Cole et al., 1977; Gupta and Germida, 1988; Treonis and Lussenhop, 1997; Frey et ”
Bacterial and Fungal Contributions to Carbon Sequestration in Agroecosystems (2006, background): “Variability in MGE estimates may also be attributable, in part, to the use of different methodologies, each approach being based on a different set of assumptions (Frey et al., 2001).”
