Abstract
Saccharomonospora viridis (Schuurmans et al. 1956) Nonomurea and Ohara 1971 is the type species of the genus Saccharomonospora which belongs to the family Pseudonocardiaceae. S. viridis is of interest because it is a Gram-negative organism classified among the usually Gram-positive actinomycetes. Members of the species are frequently found in hot compost and hay, and its spores can cause farmer’s lung disease, bagassosis, and humidifier fever. Strains of the species S. viridis have been found to metabolize the xenobiotic pentachlorophenol (PCP). The strain described in this study has been isolated from peat-bog in Ireland. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of the family Pseudonocardiaceae, and the 4,308,349 bp long single replicon genome with its 3906 protein-coding and 64 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.
Highlights
Strain P101T (= DSM 43017 = ATCC 15386 = JCM 3036 = NCIMB 9602) is the type strain of Saccharomonospora viridis, and the type species of the genus Saccharomonospora [1,2], which currently contains eight species [3]
Saccharomonospora viridis type strain P101 has been reported by Lu and Liu from Chinese soil (AF127525)
It was suggested that S. viridis metabolizes PCP by conjugation to form a more polar transformation product, but, unlike other PCP-degrading bacteria, the organism is incapable of effecting total degradation of the xenobiotic [14]
Summary
Strain P101T (= DSM 43017 = ATCC 15386 = JCM 3036 = NCIMB 9602) is the type strain of Saccharomonospora viridis, and the type species of the genus Saccharomonospora [1,2], which currently contains eight species [3]. Phylogenetically a member of the Gram-positive actinomycetes, already the initial report on S. viridis strain P101T noticed the astonishing feature of the organism to be Gram-negative, despite showing the typical mycelium morphology of Saccharomonospora [2]. Spores of S. viridis are readily dispersed in air, and the prolonged exposure to spores can apparently result in acute respiratory distress (farmer’s lung disease) which may lead to irreversible lung damage [4,5]. We present a summary classification and a set of features for S. viridis P101T, together with the description of the complete genomic sequencing and annotation
