This document discusses past and present research on antibiotic-producing actinomycetes. It covers key discoveries from the 1940s-1960s, including antibiotics like penicillin, tetracyclines, and cephalosporins. Current research focuses on genomics, combinatorial chemistry, and high-throughput screening, which have not yielded new antibiotics. The document advocates returning to whole-cell screening of actinomycete broths, which more directly tests for antibiotic activity. It also describes using macrodroplets to simplify actinomycete culturing and screening against drug-resistant E. coli to identify promising new antibiotic candidates. Challenges with metagenomic approaches are noted.
