Bioremediation is a treatment process that uses microorganisms (including bacteria) and plants to degrade toxic contaminants into less toxic or non-toxic substances. Bioremediation technologies can be applied in situ without the need for removal and transport of contaminated soil and offer a sustainable solution to the problem of contaminated land.
A critically important component of the soil/plant microbiome are Plant Growth Promoting Bacteria or PGPB. Application of PGPBs to crop plants have been shown to significantly increase crop yield when used in low input agricultural systems. This leads to a reduction in the use of expensive fertilizer and other costs for the farmer and can also reduce the carbon footprint of intensive crop production.
Stressed soil can be a major inhibitor of agricultural production and globally represents a considerable loss in potential crop yield. Stresses can be biotic (e.g. plant pathogens and insect pests) or abiotic (e.g drought, salinity, heavy metals). The general impacts of stresses on crops include nutritional and hormonal imbalances and increased sensitivity to disease.
