The substrate quality gradient will determine if higher resource quality inputs have the potential to divert more C into more stable SOM. Leading hypotheses about controls on MAOC formation center on soil microbial ecophysiology, soil mineralogy, legacy management-induced MAOC stocks, and pH. Yin X, Zhou G, Cai M, et al. Year Published: Int. Appropriately using phosphorus (P) for the fertilization of sugarcane is critical to achieving high productivity because it is one of the most limiting nutrients in agricultural cropping systems. Citation: Juan Jos Haristoy Lagos (former Undergraduate student, graduated 2012) Furthermore, there were no differences in the abundances of corn tissue and root lipids between organic and conventional, suggesting that the selective preservation of roots or corn tissue is not a mechanism driving differences in soil carbon between the treatments. Nothing Reported Our fantastic team uses omics analysis combined with detailed functional characterization of proteins, cofactors, and metabolites to further our understanding of the regulation of cellular processes and ultrastructure in archaea, as well as their ability to interact with other organisms and survive under stress conditions. Microbial physiology was linked to how new C inputs are processed into various soil C pools and biomarker analyses will determine how differences in observed C allocation strategies influence the production of stable microbially-derived soil C. Results from this research show organic cropping systems in Michigan build more microbial biomass through higher growth rates and growth efficiencies and that newly added carbon is more likely to be sequestered into stable soil carbon pools relative to the conventional agricultural sites. More glucose was recovered in MBC (~20%) relative to phenol (~2.5%) in both treatments. This project hypothesized differences in microbial community physiology and how plant carbon is utilized can explain higher soil C sequestration in organic agricultural systems despite similar or fewer new plant carbon inputs. The microbial ecology of a range of anaerobic biological assemblages (granular sludge) from full- and laboratory-scale wastewater treatment bioreactors, and of crop-growing and peat soils, was determined using a variety of 16S rRNA gene-based techniques, including clone library, terminal restriction fragment length polymorphism (TRFLP) and denaturing gradient gel electrophoresis (DGGE) analyses.

Published Microbial physiology can reasonably be defined as "structure-function relationships in microorganisms, especially how microbes respond to their environment". Now, it is possible to enrich anammox bacteria up to 95% with a membrane bioreactor that removes forces of selection for fast settling aggregates and facilitates the growth of planktonic cells.

Year Published: Microbiomes in extremely acidic environments: functionalities and interactions that allow survival and growth of prokaryotes at low pH. Recently, our epistemology of soil C dynamics has been undergoing a major transformation; where in the past soil organic matter (SOM) formation was attributed to the biochemical recalcitrance of plant litter, we now know that microbially transformed plant residues and microbial necromass are key precursors of SOM formation.

PhD Position on the metabolism of photorophic bacteria: Czech . Front. How these differences in physiology translate into the microbial processing of new soil C inputs was tested in goal #2. These data suggest that even though more phenol C is utilized by the microbes in the organic system, as evidences by the higher recovery in microbial biomass, that more C is ultimately retained in stable soil fractions under organic management within the after 12 months of substrate addition. 8: 456.
