Many microbes secrete antimicrobial compounds to help them compete with other microorganisms for habitat. Some of the bacteria that are common antibiotic producers are the Actinomycetes (including ''Streptomycetes'' species), many of the ''Bacillus'' species, and the fruiting myxobacteria, to name just a few among many, many antibiotic producing bacteria.
