Lineage: Streptomyces bingchenggensis; Streptomyces; Streptomycetaceae; Actinomycetales; Actinobacteria; Bacteria

General Information: Streptomyces bingchenggensis BCW-1 was isolated from a soil sample collected in Harbin, China. This species produces milbemycins, a family of macrocyclic lactones widely used in human health, animal health, and crop protection. The characteristic earthy smell of freshly plowed soil is actually attributed to the aromatic terpenoid geosmin produced by species of Streptomyces. There are currently 364 known species of this genus, many of which are the most important industrial producers of antibiotics and other secondary metabolites of antibacterial, antifungal, antiviral, and antitumor nature, as well as immunosuppressants, antihypercholesterolemics, etc. Streptomycetes are crucial in the soil environment because their diverse metabolism allows them to degrade the insoluble remains of other organisms, including recalcitrant compounds such as lignocelluloses and chitin. Streptomycetes produce both substrate and aerial mycelium. The latter shows characteristic modes of branching, and in the course of the streptomycete complex life cycle, these hyphae are partly transformed into chains of spores, which are often called conidia or arthrospores. An important feature in Streptomyces is the presence of type-I peptidoglycan in the cell walls that contains characteristic interpeptide glycine bridges. Another remarkable trait of streptomycetes is that they contain very large (~8 million base pairs which is about twice the size of most bacterial genomes) linear chromosomes with distinct telomeres. These rearrangements consist of the deletion of several hundred kilobases, often associated with the amplification of an adjacent sequence, and lead to metabolic diversity within the Streptomyces group. Sequencing of several strains of Streptomyces is aimed partly on understanding the mechanisms involved in these diversification processes.

Subject: NC_012522:3867167 Rhodococcus opacus B4, complete genome

Lineage: Rhodococcus opacus; Rhodococcus; Nocardiaceae; Actinomycetales; Actinobacteria; Bacteria

General Information: Strain B4 was isolated from a soil sample taken from the roadside in Hiroshima, Japan. It is a benzene-tolerant, Gram-postitive, non-motile, strictly aerobic rod, able to use many organic compound as its sole source of carbon and energy. Rhodococcus opacus is an aerobic, Gram-positive bacterium that can accumulate triacylglycerols (TAGs).
