Question: How Safe Are Microbes?
FACT AND FICTION
FACT AND FICTIONBy: Onofre Ortiz and Thomas W. McNally
Answer: Classified American Type Culture Collection (ATCC) Class I Organisms are nonpathogenic, completely safe to use and have no recognized hazard potential under ordinary conditions of handling.
Answer: This classification is assigned only after extensive study and review by ATCC and government committees.
Answer: Class I Organisms are subject to unrestricted
distribution by the ATCC, U.S. Department of Health, Public Health Service and the Toxic Substances Control Act (TOSCA).

Answer: Once active, the rate at which the microbes can remediate hydrocarbons can approach 80% every seven days. Analyses performed on samples of used surfactant taken from a bioremediating parts washer operating consistently show oil and grease levels in the 1,400 parts per million range. BY COMPARISON, used, non-bioremediating, aqueous cleaners can average over 20,000 parts per million of oil and grease.
Question: How quickly can microbes breakdown contaminants?

Answer: As with all parts cleaners, excessive greases, oils and fluids should be disposed of prior to washing parts and NOT used as a waste oil dump. That said, most bioremediating parts washers can handle large, tough, dirty jobs.
Question: How much oil can I put into a bioremediating parts washer at one time?
Answer: YES. The bioremediation process that takes place in the solution frees the surfactants allowing them to clean and emulsify even more contaminants.
Question: Do microbes improve the cleaning ability of aqueous cleaners?

Question: In addition to oil, will bioremediating parts washers clean other substances?Answer: Microbes have been successfully
used on a variety of contaminants including the following:
CRUDE OIL OILS SOLVENTS BTEX GREASES
AMINES CREOSOTE PHENOLS PCP FATS PNA
FACT AND FICTION
Question: Do the microbes need to be in a heated environment to survive?Answer: Microbes will slow down their
remediation and reproduction rate but not die at low temperatures. The microbes work at a more efficient rate in a warmer environment and it is a more enjoyable cleaning experience for the user if the solutions are heated. FACT AND FICTION

Question: Is there anything that could kill the microbe in a bioremediating parts washer?Answer: YES. Any biocides designed to kill
microbes, such as bleach or chemicals that kill living things like some strong pesticides and rat poisons.
Bioremediation represents the safe, effective and sustainable
method for parts cleaning.
