The genus Geobacillus was created by Nazina et al. (Int J Syst Evol Microbiol 51:433–446, 2001) to accommodate thermophilic, Gram-positive, endospore-forming bacteria originally belonging to the genus Bacillus, plus other new species of hydrocarbon-oxidizing organisms isolated from heated, hydrocarbon-rich environments. Proposals for further new Geobacillus spp. with the ability to grow at elevated temperatures and degrade hydrocarbons, followed. In this chapter we discuss the characteristics, growth, metabolism and hydrocarbon degradation abilities of some members of Geobacillus. In addition, their general genetic traits, geographical distribution and potentials for use in hydrocarbon-contaminated soil remediation processes are presented.
