Antimicrobes are agents that inhibit the growth (bacteriostatics) of microorganisms, or kills them (microbicides) completely. Most commonly known microbiomes are the antibiotics and anti-fungals, which are focused on the inhibition of bacteria of fungi, respectively. Extensive developments that are ongoing are identifying novel, less harmful antimicrobial agents and techniques. These include essential oils, plant-based components and optimized physical treatments using heat or radiation.
