Anaerobic Food Supplement

Improves Methane Generation in Anaerobic Processes With Inconsistent Loading

  • Use in anaerobic processes.
  • Works with all types of loading.
  • Meets the specific needs of anaerobic microorganisms by providing COD and soluble micronutrients – allows for better methane generation
  • Creates operational consistency. 
  • Improves the digester microbiota, stabilizing the pH.
  • Great for start-up biodigesters


When methanogens become stressed they lose the ability to produce methane, which leads to a buildup of volatile acids. That build up reduces the pH which causes the digester to be acidic (sour) and leads to poor digester performance. Generally, a digester is considered sour if the pH is too low to allow for significant amounts of methane production. Generally, this occurs below pH 6. If a digester is already sour, the pH should be adjusted before any other treatment is attempted. Sour digesters have a buildup of methanogen substrates which means the food supplement may actually make the problem worse. After a neutral pH has been reestablished, the food supplement can be used to improve pH stability.

Anaerobic digesters contain a variety of facultative bacteria, strict anaerobic bacteria, and archaea (such as methanogens) which allow a digester to break down volatile solids. Volatile solids are converted to soluble compounds by hydrolysis and then to short chain fatty acids by the acid generating bacteria. Once short chain volatile acids are present in an anaerobic system, the methane generators use the acids to produce biogas (primarily methane and carbon dioxide). The archaea responsible for methane production are much more susceptible to adverse conditions than acid generating bacteria (acetogens) and this is why anaerobic food supplement is so helpful. Anaerobic food supplement supplies methanogens with the COD and micronutrients they need so their populations can build during periods of low nutrient loading.

Product Pairings

BioGas1 supplies methanogen-producing bacteria with the most important trace elements to help them convert food sources into gas, creating a more stable and productive anaerobic digester.

Ana-Zyme G handles the volatile fat, oil, and grease that enters anaerobic digesters and can cause foaming and upsets. Anaerobic digesters that use Ana-Zyme G are less likely to go sour than digesters that don’t.

Applications and Benefits

  • Great for variable high loadings or persistent low loadings.
  • Helps in building methanogen populations.
  • Helps with a new digester start up.
