[Recent advance in Geodermatophilaceae--A review].

The family Geodermatophilaceae is a newly established actinobacterial taxon. Normand ever proposed the family Geodermatophilaceae in 1996, which was recognized as an invalid taxon at that time. In 2006, based on the common characteristics of the genera Geodermatophilus, Blastococcus and Modestobacter, Normand summarized the typical characteristics of Geodermatophilaceae, then the family Geodermatophilaceae was finally accommodated as a validly described taxon in the phylum Actinobacteria. Up to date, the family Geodermatophilaceae consisted of 3 genera, i. e., Geodermatophilus, Blastococcus and Modestobacter, including 25 validly described species. The members of the family Geodermatophilaceae were considered as biologic pioneers in extreme environments, exhibiting many potential advantages in the study of mechanism of stress resistance, desertification control and environmental remediation. The objective of this review is to summarize the research advances in the family Geodermatophilaceae, including the establishment and taxonomic characteristics of the family, as well as their application prospect and the roles in the field of ecology.
