Bacteria – What are the Facts? • Bacteria have dietary preference
• Bacteria have optimum performance under specific conditions
• Digesting organic matter is a multi-step process
• Not all bacteria are equal
• Not all bacteria grow at the same rate
• There are “good guys” and “bad guys” always present
• Ratio of Good:Bad depends on food available and how many of the “Good Guys” are available
Bacteria – How does it Work?
Where do they come from?
• The bacteria are all naturally occurring and have been extracted from soil
• None of the bacteria have been genetically engineered or modified
• Bacteria survive by eating food, for example grease, fat, sugar even
oil - any material with a carbon food source
How much bacteria are needed?
• That is generally known through experience
• With more than 20 years experience in treating waste using biotechnology,
we give recommended dose rates for treating various wastes
• In contaminated water bodies, we suggest a dose of 1kg product for 1000m3
of water and then adjust the dose rate according to the results
If bacteria multiply why do we need to add more?
• Bacteria like humans
• Will die after a period of time
• If waste is continually added, new bacteria need to be added to keep the number
of live bacteria correct to eat the waste
• If no more waste is being added, then once the waste has been treated, no more bacteria are needed
How do they stop growing?
• Bacteria are a living organism so they will have a finite lifetime depending upon
the environment they are in
• Obviously, if all the food (waste) has been eaten they will die.
• Dead bacteria are minute particles (like fine yeast) and will combine together in larger solids.
How do you keep them stable in the products?
• The bacteria need moisture or water to grow
• Powder formulations are very stable
• Liquid formulations have a preservative that doesn’t kill the bacteria but will stop it from growing
• Bacteria are activated either when the product is diluted to the working concentration or
comes into contact with some food
