The increase in cases of antibiotic resistance and the discoveries cessation of new classes of antibiotics encourages the exploration of various microorganism sources from unique environments to produce antimicrobial compounds.

Therefore, Micromonospora sp. 2310 could be considered a great potential antibacterial producer.
