High nitrate concentration together with high salinity of the groundwater in the area of Lake Karachai may enhance the activity of halophilic and denitrifying microorganisms. Those microorganisms affect transformation of chemical species of radionucl

We examined the Mn(II) oxidation performance of a bacterium, BY86, collected at Yunotaki Falls Hokkaido, Japan. The bacterium showed rapid oxidation of Mn(II), and brown precipitates containing Mn formed within a few days of incubation. The presence

We conducted a series of basic studies on the microbial accumulation of actinides to elucidate their migration behavior around backfill materials used in the geological disposal of radioactive wastes. We explored the interactions of U(VI) and Pu(VI)

To establish a relationship between the secondary structure of a peptide and the quadrupolar coupling of its amide (14)N, we examined (14)N quadrupolar couplings for eight different polypeptide samples, each of whose secondary structure (alpha-helix

A model analysis of the transformation of Pu(VI) in a mixture of a common soil bacterium, Bacillus subtilis, and kaolinite clay was carried out. A simplified kinetic model, where the adsorptions of Pu(VI) and Pu(V) are assumed to be in instantaneous

It is extremely important to elucidate the formation mechanism of the secondary structure in polypeptides and proteins. This enables the stability of the three-dimensional structure of proteins to be predicted theoretically. For this purpose, the dev

The sorption of U(VI) on the 4-mercaptopyridine self-assembled monolayer (4-PyS-SAM) on Au(111) was studied by cyclic voltammetry. Cyclic voltammograms (CVs) of the 4-PyS-SAM working electrode were obtained by contact with 1mM UO2(NO3)2 solution, 1mM

We studied the effect of ionic strength on the interactions of Europium(III) and Curium(III) with a Gram-negative bacteriumParacoccus denitrificans. Bacterial cells grown in 0.5-, 3.5-, and 5.0% NaCl were used in adsorption experiments and laser expe

We examined the reduction behavior of UO22+in citrate media at pH 2.0−7.0 by column electrodes. At pH 2.0, UO22+was reduced to U(IV) through a one-step reduction process, while it was reduced to U(IV) through a two-step reduction process at pH 3.0
