Title
Metabolic engineering of antibiotic factories: new tools for antibiotic production in actinomycetes
Abstract

•Actinomycetes are rich sources of diverse bioactive compounds.•Various genome-mining tools have been developed for actinomycetes.•Several genome-engineering tools have been developed for actinomycetes.•Novel antibiotics can be produced by metabolic engineering of actinomycetes.•Antibiotics production can be enhanced by metabolic engineering.

Actinomycetes are excellent sources for novel bioactive compounds, which serve as potential drug candidates for antibiotics development. While industrial efforts to find and develop novel antimicrobials have been severely reduced during the past two decades, the increasing threat of multidrug-resistant pathogens and the development of new technologies to find and produce such compounds have again attracted interest in this field. Based on improvements in whole-genome sequencing, novel methods have been developed to identify the secondary metabolite biosynthetic gene clusters by genome mining, to clone them, and to express them in heterologous hosts in much higher throughput than before. These technologies now enable metabolic engineering approaches to optimize production yields and to directly manipulate the pathways to generate modified products.
