Surfactin is a powerful biosurfactant produced by the bacterium Bacillus subtilis. It is known for its ability to reduce surface tension between liquids, making it useful in various applications, including cleaning products and oil recovery. Surfactin is also recognized for its antimicrobial properties, which can help inhibit the growth of certain bacteria and fungi. In addition to its industrial uses, surfactin has potential in medical and agricultural fields. Its unique structure allows it to interact with cell membranes, which may lead to new treatments for infections or enhance the effectiveness of pesticides. Researchers continue to explore its diverse applications and benefits.
