_DSC0176_pFuels are often used in environments where microbes can thrive.  With higher levels of humidity, available food sources and, for bacteria, a lack of direct light, these environments can make for prime growing conditions.

Antimicrobial additives used in fuel can run into challenges not seen in other environments.  These challenges can have an effect on the performance of the antimicrobial, and fuel producers and distributors often rely on specialized test methods to ensure the antimicrobial works as intended.

One common fuel test, ASTM E1259, is used for assessing the ability of an additive to eliminate microbial growth quickly and also determined for how long the additive will work before breaking down.

Fuels are also increasingly required to be tested for biodegradability.  Where fuels may enter the natural environment, a liquid-based biodegradation test like the OECD 301B is a good choice.

Recognized globally, OECD 301B provides both ready and ultimate biodegradation values for liquids, formulations, solvents and fuels.
