Environmental Bioremediation

WHO CAN ENVIRONMENTAL BIOREMEDIATION HELP?

Oilfield and oil refining industries: to treat oil impacted soil, oil sludge, and oil spills
Coal/gas industries: TPH and PAH impacted soil pollution
Governments and farmers: treating contaminated agricultural land while increasing crop yield
Environmental remediation companies: treating TPH and/or PAH impacted material
Dredging industries: pollutants impacted sludge/sediment

WHAT ARE THE BENEFITS?

• Low cost
• Environmentally friendly (no chemical treatments or incineration)
• Treat mixed contaminants
in situ method (no transportation costs)
• Can be used to treat very large volumes of soil
• No toxic end products
• Stabilize heavy metal pollutants in soil matrix (prevents dispersal by wind etc.)
• Creates a “green” ecosystem when used with a phytoremediation approach

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. However, conditions in the contaminated environment need to be optimized for effective biodegradation of the target contaminants, i.e., the levels of moisture, pH and temperature in the soil will dictate survival ranges for microorganisms and plants used for bioremediation, abundant oxygen will facilitate mineralization of soil contaminants, concentrations of nutrient and hydrocarbons in the soil will need to be balanced for efficient bioremediation, and suitable microorganisms and plants will be required to degrade and/ or mineralize target contaminants.

Bioremediation technologies compare extremely favourably with traditional remediation technologies when analysed using sustainability remediation metrics.

MicroGen Biotech have collected and analysed contaminated soil samples from around the world. By applying our “Constructive Functional Microbiome” and “High Throughput Screening” technologies, we have built a library of microbes with the ability to work with a broad range of environmental contaminants including heavy metal, TPHs, PAHs and numerous pesticides e.g. 2,4-D and atrazine. We can provide a consortia of strains to suit your specific needs and requirements to deal with one or more pollutant types. These can be applied to your site using our bead delivery system or through our patented EcoPile™ system.

In addition, we can prepare and deliver a designed (tailored) consortia of strains based on the microbiota of your site (supplemented with microbes from our libraries if specific microbe categories are absent). Our microbes encode the genes and enzyme pathways necessary for the removal or degradation of the target pollutants to harmless end-products (such as carbon dioxide and water).

Our experience with plant associated microbes in combination with selected plants gives us a unique series of bioremediation products and solutions applicable to diverse polluted soils (industrial and agricultural) and sediments.
