Abstract
Thiothrix nivea (Rabenhorst 1865) Winogradsky 1888 (Approved Lists 1980) emend. Larkin and Shinabarger 1983 is the type species of the genus Thiothrix in the family Thiotrichaceae. The species is of interest not only because of its isolated location in the yet to be genomically characterized region of the tree of life, but also because of its life-style with gliding gonidia, the multilayer sheath, rosettes, and the embedded sulfur granules. Strain JP2T is the neotype strain of the species which was first observed by Rabenhorst in 1865 and later reclassified by Winogradsky in 1888 into the then novel genus Thiothrix. This is the first completed (improved-high-quality-draft) genome sequence to be published of a member of the family Thiotrichaceae. The genome in its current assembly consists of 15 contigs in four scaffolds with a total of 4,691,711 bp bearing 4,542 protein-coding and 52 RNA genes and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
Highlights
Strain JP2T (= DSM 5205 = ATCC 35100) is the type strain of Thiothrix nivea [1,2] which is the type species of the genus Thiothrix [1,2]
The species was included on the Approved List of Bacterial Names Amended edition in 1980 [4]
The species became well known for its sulfur granules, the gliding motility and the typical rosettes [1], which were first observed by Winogradsky [2]
Summary
Strain JP2T (= DSM 5205 = ATCC 35100) is the type strain of Thiothrix nivea [1,2] which is the type species of the genus Thiothrix [1,2]. Cultures of the species were first observed and classified as “Beggiatoa nivea” in 1865 by Rabenhorst [3] and later (1888) placed into the novel genus Thiothrix by Winogradsky [2]. The generic name derives from the Neo-Greek words theion, sulfur, and thrix, hair [6]. The species epithet is derived from the Latin word nivea snow-white [6]. The species became well known for its sulfur granules, the gliding motility and the typical rosettes [1], which were first observed by Winogradsky [2]. We present a summary classification and a set of features for T. nivea JP2T, together with the description of the complete genomic sequencing and annotation
