Summary

These datasets are from an incubation experiment with a combination of two minerals (feldspar or amorphous aluminum hydroxide), one living species of bacteria (Escherichia coli), and one added form of C (Arthrobacter crystallopoietes necromass). We characterized the sorptive properties of the minerals with batch sorption experiments using four low molecular weight C substrates (glucose, oxalic acid, glutamic acid, p-hydroxybenzoic acid): this data is provided in the SterileSorptionData file. We then conducted a 3-wk long incubation in serum vials or imaging chambers. In both incubations, feldspar (200 mg) or amorphous aluminum hydroxide (100 mg) was given 1 of 4 different treatments: (1) a water control with autoclaved 18 MΩ water, [...]

Purpose

The purpose of this experiment was to determine the role of mineralogy and microbial processing on the retention of microbial C on mineral surfaces. These data were collected to test whether mineralogy influenced the pathway of necromass association with minerals. Specifically, we tested whether microbial necromass directly sorbed to mineral surfaces or was consumed by live microorganisms prior to mineral association. Examples of appropriate uses of these data would be: inclusion of the mass balance or sorption data in a meta-analysis, inclusion of this data in a model for sorption or microbial assimilation or C substrates on different minerals, or analysis of the Raman spectra for comparison to other data on changes in mineral-associated chemistry through time or on different minerals.
