 BIOREMEDIATION : Definition
Degradation of
organic matter using
microorganisms
(bacteria, fungi & algae)


BIOREMEDIATION Cycle :
bacteria
bacteria reproduce
bacteria
excretes CO2
and water
secretes enzymes
enzymes attack
grease, fats, oils –
which allow the bacteria to
eat the broken down
pieces.

 Bioremediation via Biodegradation
(the breakdown of organic
substances by microscopic
organisms)
 bioremediation is the use of biodegradation to
break down pollutants in soil, air or groundwater.

 SYSTEM Advantages :
Bioremediation is a Natural and Safe
Process.
FACT AND FICTION
By: Onofre Ortiz and Thomas W. McNally
 SYSTEM Advantages :
Bioremediation eliminates the need
for transportation of spent solvents
and other hazardous materials.
FACT AND FICTION
By: Onofre Ortiz and Thomas W. McNally
 SYSTEM Advantages :
 Bioremediation
can remediate
the
contaminants (in
situ) in place,
and does not
generate waste
products.
FACT AND FICTION
By: Onofre Ortiz and Thomas W. McNally
 SYSTEM Advantages :
Bioremediation allows for minimal environmental
impact.
FACT AND FICTION
By: Onofre Ortiz and Thomas W. McNally
 SYSTEM Advantages :
 Bioremediation completely
breaks down contaminants to
innocuous end products.
FACT AND FICTION
By: Onofre Ortiz and Thomas W. McNally
 SYSTEM Advantages :
Bioremediation is more economical than traditional
technologies.

Question: How Safe Are Microbes?
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).

 FACT AND FICTION
Question: How quickly can microbes
breakdown contaminants?
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.

works

 FACT AND FICTION
Question: How much oil can I put into a
bioremediating parts washer at one
time?
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.

 FACT AND FICTION
Question: Do microbes improve the
cleaning ability of aqueous
cleaners?
Answer: YES. The bioremediation process that
takes place in the solution frees the
surfactants allowing them to clean and
emulsify even more contaminants.
FACT AND FICTION
By: Onofre Ortiz and Thomas W. McNally
 FACT AND FICTION
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.

 CONCLUSION
 Bioremediation represents the safe,
effective and sustainable method for
parts cleaning.
