Microbial community response to addition of polylactate compounds to stimulate hexavalent chromium reduction in groundwater
► Polylactate-based electron donors were evaluated to stimulate Cr(VI) removal. ► Polylactate compounds accelerated Cr(VI) removal relative to no carbon or lactate. ► H 2 concentration, bacterial biomass and activity were highest with polylactates. ► Bacterial community composition was related to H...

| description | ► Polylactate-based electron donors were evaluated to stimulate Cr(VI) removal. ► Polylactate compounds accelerated Cr(VI) removal relative to no carbon or lactate. ► H
2 concentration, bacterial biomass and activity were highest with polylactates. ► Bacterial community composition was related to H
2 concentration.
► Pseudomonas spp. were stimulated with all forms of lactate.
To evaluate the efficacy of bioimmobilization of Cr(VI) in groundwater at the Department of Energy Hanford site, we conducted a series of microcosm experiments using a range of commercial electron donors with varying degrees of lactate polymerization (polylactate). These experiments were conducted using Hanford Formation sediments (coarse sand and gravel) immersed in Hanford groundwater, which were amended with Cr(VI) and several types of lactate-based electron donors (Hydrogen Release Compound, HRC; primer-HRC, pHRC; extended release HRC) and the polylactate-cysteine form (Metal Remediation Compound, MRC). The results showed that polylactate compounds stimulated an increase in bacterial biomass and activity to a greater extent than sodium lactate when applied at equivalent carbon concentrations. At the same time, concentrations of headspace hydrogen and methane increased and correlated with changes in the microbial community structure. Enrichment of
Pseudomonas spp. occurred with all lactate additions, and enrichment of sulfate-reducing
Desulfosporosinus spp. occurred with almost complete sulfate reduction. The results of these experiments demonstrate that amendment with the pHRC and MRC forms result in effective removal of Cr(VI) from solution most likely by both direct (enzymatic) and indirect (microbially generated reductant) mechanisms. |
