ALKEN ENZ-ODOR® 12 is a broad-spectrum bacterial blend, featuring ten specially selected, synergistic gram-positive, spore-forming Bacillus, designed to liquefy, metabolize and deodorize landfill waste. Recently reformulated for increased spectrum of odor control including hydrogen sulfide and fatty acids, for the ability to degrade petroleum hydrocarbons (crude oil, diesel and gasoline) found in leachate and for increased rate of degradation of paper wastes, food fat and greases. ALKEN ENZ-ODOR® 12 includes a special oxygenating biocatalyst and Yucca schidigera, for improved penetration and activity. Although not relying on masking perfume for odor-control, ALKEN ENZ-ODOR® 12 does contain the popular, classic Enz-Odor® wild hyacinth fragrance. Applications include waste treatment lagoons, sludge drying beds, landfills, and food product wastes. This is the highest count liquid product available for landfill application.


  Bacteria count:  400 million CFU/ml
 Appearance:  Opaque forest green liquid
  Odor: Wild hyacinth fragrance added
 pH:  6.0 TO 7.0


  • Degrades petroleum hydrocarbons in landfill leachate and refinery lagoons.
  • Degrades paper residues found in landfill leachate, including.carboxymethylcellulose, cellulose and xylan.
  • Utilizes the sugars released by degradation of xylan and cellulose.
  • Rapidly oxidizes hydrogen sulfide odor.
  • Degrades acetic, butyric, lactic, oleic, isobutyric, isovaleric palmitic, propionic, stearic and valeric fatty acids
  • Improved decomposition of food fats, greases and oils.
  • Improved starch and protein digestion
  • Degrades lignosulfonate, originating in some pesticides and chemical water treatment for boilers
  • All microbial strains are saprophytic and non-pathogenic, Class 1 microbes.
  • Effective over a wide temperature range - 9.4 degrees to 46 degrees C (49 degrees to 115 degrees F)
  • Effective over a wide pH range - 4.5 to 8.0


For large areas, mix 1 quart of ALKEN Enz-Odor® 12 with 500 gallons of water and apply at a rate of 500 gallons of mix per surface acre, as often as necessary to maintain odor control (daily to weekly applications are usual). Avoid using herbicides or disinfectants when using this product.


ALKEN ENZ-ODOR® 12 is packaged in 5-gallon plastic pails. Store in a cool place. DO NOT FREEZE PRODUCT. Avoid contact with eyes, skin, and open wounds. Wash hands with soap and water after handling.
