Antimicrobial activity and biosynthetic potential of cultivable actinomycetes associated with Lichen symbiosis from Qinghai-Tibet Plateau.

Actinobacteria that inhabit lichen symbionts are considered a promising yet previously underexplored source of novel compounds. Here, for the first time, we conducted a comprehensive investigation with regard to strain isolation and identification of lichen-associated actinobacteria from Tibet Plateau, antimicrobial activity screening, biosynthetic genes detection, bioactive metabolites identification and activity prediction. A large number of culturable actinomycetes were isolated from lichens around Qinghai Lake, in Qinghai-Tibet Plateau.

Draft Genome Sequence of Streptomyces morookaense DSM 40503, an 8-Azaguanine-Producing Strain.

Here, we describe the genome of DSM 40503, an 8-azaguanine-producing strain. The genome is the basis for future study and presents an underexplored taxonomy and biosynthetic potential, which expands our understanding of the diversity of microorganisms that produce nitrogen heterocyclic compounds.
