Abstract
We report here the draft genome sequences of two novel strains of Streptomyces (NWU339 and NWU49) isolated from South African rhizosphere soils. Both strains were found to possess strong cellulolytic activity and contain numerous putative cellulase genes. Both genomes possess benzoate degradation pathways, while NWU49 contains the genomic potential for enediyne biosynthesis.

We report here the draft genome sequences of two novel strains of Streptomyces (NWU339 and NWU49) isolated from South African rhizosphere soils
A comparison of NWU49 to the genome of Streptomyces ghanaensis ATCC 14672 using the Genome-to-Genome Distance Calculator 2.1 [8] indicates that they are likely the same species (96.27% probability that DNA-DNA hybridization is greater than 70% using formula 2)
KEGG analysis suggests the genomic potential for metabolic pathways to degrade benzoate, toluene, and xylene
Summary
We report here the draft genome sequences of two novel strains of Streptomyces (NWU339 and NWU49) isolated from South African rhizosphere soils. The genome of NWU339 encodes 8,776 protein-coding sequences (CDSs), 8 rRNA genes, and 88 tRNAs. Phylogenetic analysis of taxonomic marker genes using MetAnnotate [7] revealed NWU339 to be a novel Streptomyces strain with 97% 16S rRNA identity to Streptomyces poonensis NRRL B-2319. The genome of NWU49 encodes 8,021 CDSs, 7 rRNA genes, and 100 tRNAs. NWU49 possesses 98% 16S rRNA identity to Streptomyces ghanaensis NBRC15414.
