Soil is a habitat for microorganisms and also serves as reservoir for their metabolites. The genus Streptomyces is one of prominent soil inhabitant, comprising up to 90% of actinomycetes isolated from soil samples. Streptomyces is the largest and the most important genus in the order actinomycetales. The genus Streptomyces is prolific producers of bioactive secondary metabolites that have important applications both in medicine and agriculture. In the history of drug discovery, majority of novel substances of microbial origin are isolated from Streptomyces, over two-thirds of all microbial antimicrobial agents are derived from them. Many novel drugs have been developed from Streptomyces spp. including S. griseus, S. hygroscopicus, S. coelicolor, S. avermitilis, S. rochei, S. plicatus, S. fungicidicus, S. flaveus, and S. globisporus; belonging to different classes of antibiotics such as aminoglycosides, ansamycins, anthracyclines, glycopeptides, Î²-lactams, macrolides, nucleosides, peptides, polyenes, polyethers, and tetracyclines. These organisms are of high biotechnological and commercial values; and continue to be routinely screened for new bioactive compounds. Streptomyces spp. is aerobic, filamentous, Gram positive soil dwelling bacteria with high G+C content in their genomic composition.

In the growing environment, they are many journals in various organisations. Only a very few journals maintain high standards in terms of the content they publish, one has to be careful while picking information as content that is not reliable and untrue can be harmful to research as well as society. Generally, journals can be rated by considering impact factor, reputation of authors, editorial board members and also in terms of the fee they charge. Only high indexing journals have quality articles. Molecular Biology is one of the best journals which publish quality articles.
