Soil remediation — DeCoBac

There are many different causes for soil conta­mi­nation with harmful chemical substances. One approach to clean up organic conta­mi­na­tions, e.g. oil or fuel spills from soil, is the micro­bio­lo­gical remediation process.

A number of conta­mi­na­tions can easily and cost-effective degraded by naturally occurring (autocht­honic) or additio­nally intro­duced (allochthoinc) micro-organisms. Accom­panying measures such as chemical analyses should monitor the remediation process.

The soil-innate micro-flora can often be activated by addition of missing nutrients or oxygen. With these simple measures an increased microbial activity can result in an effective degra­dation process. Specific inves­ti­gation to analyse the nutrient requi­re­ments of organisms can by carried out by MicroPro GmbH.

DeCoBac – if external help is required.

DeCoBac is a stable mixture of bacteria, speci­fi­cally selected and adapted to degrade a wide range of hydro­carbons under aerobic condi­tions. In case the autocht­honic (on-site) soil micro flora does not degrade hydro­carbon conta­mi­na­tions, the degra­dation potential can signi­fi­cantly increased by addition of active bacteria culture (e.g. in soil treatment facilities).

It has been demons­trated that speed and range of hydro­carbon degra­dation have been signi­fi­cantly increased in compa­rison to untreated samples. Extensive laboratory tests and field appli­ca­tions in various soil treatment facilities have confirmed a successful appli­cation under practical conditions.

Further information

DeCoBac — MKW is a ready-to-use liquid formu­lation of highly active bacterial cultures specially developed for soil decontamination.

DeCoBac — MKW consists of a complex mixture of selected bacterial strains that have been adapted to the specific remediation tasks in order to degrade the mineral oil hydro­carbons present in the soil in a targeted manner.

Characteristics and advantages

  • rapid degra­dation of hydrocarbons
  • non-corrosive
  • non-pathogenic (risk group 1 according to § 3 of the BioStoffV)
  • safe to handle
  • can be used immediately in the form in which it is delivered
  • parti­cu­larly effective in combi­nation with selected surfactants

Optimal conditions for use

The bacteria in DeCoBac — MKW require suitable condi­tions to achieve maximum performance:

  • pH range: 6.5 – 8.0 (optimal value close to pH 7.0)
  • tempe­rature influences the activity of the working solution;
  • process increases with rising tempe­ra­tures up to 50 °C
  • no activity can be expected below 5 °C

Storage and handling

  • Storage:
    • cool and dry,
    • can be stored for approx. 4 weeks
  • Handling:
    • follow the safety data sheets,
    • avoid direct contact,
    • aash hands with warm soapy water after handling
