Bioaugmenation and soil management

Bioaugmentation protocols to improve herbicide removal in soils have been implemented. The bioaugmentation protocol serves to assess the performance of the specialized catabolic strain both in the herbicide removal rate and in the strain survival.

To assess the effect of bioaugmentation on soil bacterial population the bioaugmentation protocol can be combined with culture independent tools and approaches also developed within the framework of this project. Bioaugmentation protocol can be applied for strains catabolizing either s-triazine herbicides such as atrazine or simazine, or chlorinated phenoxyalkanoic herbicides such as 2,4-dichlorophenoxyacetate. Use of soil microcosm studies as a previous step before field studies is recommended.

Procedures to test abiotic factor effects in both herbicide removal rates and strain survival, such as lixiviation and soil sterilization through irradiation, are also considered. Some soil management procedures such as use of plants, use of nitrogen source, or addition of antimicrobial compounds are also addressed. Although tested in three types of soils, and five different catabolic strains, the use of these protocols can be extended to other soils ad catabolic strains.
