In order to develop an understanding of the role that microorganisms play in the transport of $$^{129}$$I in soil-water systems, naturally occurring bacteria isolated from the F-area subsurface of the Savannah River Site (SRS) were assessed for iodide oxidizing activity. Spent liquid medium from a number of SRS bacterial cultures enhanced iodide oxidation 2-10 fold in the presence of hydrogen peroxide (H$$_{2}$$O$$_{2}$$). From a time-series measurements of peroxidase activities and organic acid concentrations, it was hypothesized that microbial organic acid exudate promoted iodide oxidation via following mechanisms; (1) organic acids interact with H$$_{2}$$O$$_{2}$$ to form strong iodide oxidizing agents, peroxy carboxylic acids, and (2) organic acid secretion led to enhanced rates of H$$_{2}$$O$$_{2}$$-dependent iodide oxidation by lowering the pH of the culture medium.

A Computational Infrastructure for Nuclear Astrophysics has been developed to streamline the inclusion of the latest nuclear physics data in astrophysics simulations. The infrastructure consists of a platform-indepedent suite of codes that are freely vailable online at nucastrodata.org. The newest features of, and future plans for, this software suite are give in.
