Physiological and Growth Characteristics of Shewanella Species

Abstract

This report summarizes technical effort to understand microbial interactions relevant to operational use in the marine environment. Firstly, Shewanella frigidi marina was investigated as a potential microbial fuel cell (MFC) catalyst. S. frigidimarina is halotolerant and can grow at temperatures in the range of 0-28 degrees C. The physiological characteristics of S. frigidimarina as a psychrophile provide opportunity for energy generation at unconventional operating temperatures. Secondly, the unusual growth characteristics of another Shewanella sp., Shewanella japonica, were investigated. S. japonica is also a halotolerant and metabolically diverse species and was investigated for its ability to form complex biofilms on solid surfaces in marine environments.
