The broad theme is extremophiles and adaptation to extreme environments; including cold adaptation in Antarctic archaea and low nutrient adaptation in marine oligotrophic ultramicrobacteria. The research strategy is based on genomics and phenomics, involving extensive national and overseas collaborations. Genome sequencing projects include the cold adapted archaea, Methanogenium frigidum and Methanococcoides burtonii. Microbial oligotrophy is studied through molecular and physiological studies of the marine ultramicrobacterium, Sphingopyxis alaskensis (formerly Sphingomonas). Genomics underpins programs of bioinformatics leading to global proteomic, microarray and metabolomic analyses and targeted studies of gene structure, function and regulation. A commerical arm of the work exploits the unique properties of extremozymes, and utilises novel methods for improving the thermal properties of enzymes that are important in industrial, agricultural and medical applications.
