ABSTRACT

The members of the genus Thermoactinomyces are known for their protein degradative capacities. Thermoactinomyces sp. strain AS95 is a Gram-positive filamentous bacterium, isolated from moderately saline water in the Thamelaht region of Algeria. This isolate is a thermophilic aerobic bacterium with the capacity to produce extracellular proteolytic enzymes. This strain exhibits up to 99 % similarity with members of the genus Thermoactinomyces, based on 16S rRNA gene sequence similarity. Here we report on the phenotypic features of Thermoactinomyces sp. strain AS95 together with the draft genome sequence and its annotation. The genome of this strain is 2,558,690 bp in length (one chromosome, but no plasmid) with an average G + C content of 47.95 %, and contains 2550 protein-coding and 60 RNA genes together with 64 ORFs annotated as proteases.

The strains and their corresponding Genbank accession numbers are shown following the organism name and indicated in parentheses. The phylogenetic tree was made using the neighbor-joining method with maximum composite likelihood model implemented in MEGA 7. The tree includes the 16S rRNA gene sequence of Sulfobacillus acidophilus DSM 10332T as outgroup. Bootstrap consensus trees were inferred from 1000 replicates, only bootstrap values >50 % are indicated. The scale bar represents 0.02 nucleotide changes per position.

Mentions: Thermoactinomyces strain AS95 was isolated from a sebkha water sample collected in June 2013 from the Thamelaht region ofAlgeria (Table 1). This isolate is a Gram-positive, aerobic, thermophilic, filamentous bacterium (Fig. 1) belonging to the order Bacillales. Based on the 16S rRNA gene sequence similarity searches by BLASTN against the NCBI-NT database, strain AS95 showed 97–99 % sequence similarity to members of the genus Thermoactinomyces. A 16S rRNA gene-based phylogenetic tree of Thermoactinomyces sp. strain AS95 was constructed (Fig. 2), based on neighbor-joining and maximum composite likelihood models with 1000 bootstrap replications using MEGA 7 [12]. The Thermoactinomyces sp. strain AS95 (KU942442) 16S rRNA gene sequence exhibited high identity (99 %) with Thermoactinomyces vulgaris RVH210302 (AY114167), the closest validly published Thermoactinomyces species.Table 1
