Description

This project report summarizes the results of a 3-way collaboration between researchers at Montana State University’s (MSU’s) Center for Biofilm Engineering (CBE) (Drs. Robin Gerlach and Al Cunningham), the WSU/NSF IGERT Center for Multiphase Environmental Research (CMER) at Washington State University (WSU) (Dr. Brent Peyton who recently moved to MSU), and the Idaho National Laboratory (INL) (Drs. William Apel and Frank Roberto). At WSU, removal of uranium (U) from aqueous solution was studied using Cellulomonas sp. strain ES6, under anaerobic, non-growth conditions. The Cellulomonadaceae are environmentally relevant subsurface bacteria, and strain ES6 was isolated from the DOE Hanford subsurface. To ... continued below

The Cellulomonadaceae are environmentally relevant subsurface bacteria, and strain ES6 was isolated from the DOE Hanford subsurface. To better understand the role of the pH buffer in the U immobilization process, both bicarbonate and PIPES buffers were used. Our results show for the first time the strain ES6 has multiple U immobilization mechanisms within one organism. Citations to resulting publications are included in the report.
