Application of Biofilm in Bioremediation

Introduction to Bioremediation

Application of Biofilm in Bioremediation

Bioremediation uses microorganisms to remove, detoxify, or immobilize contaminants without the addition of harmful chemicals. Bioremediation is particularly suitable for large areas where contaminant concentrations are relatively low and where soil hydrology does not support aggressive chemical remediation strategies. In the past few years, researchers have described bioremediation mechanisms for many priority contaminants, including chlorinated hydrocarbons, polycyclic aromatic hydrocarbons, and heavy metals. However, most of the studies published to date have involved planktonic cultures grown under controlled laboratory conditions. Microorganisms in the environment occur primarily as biofilms, which are promoted by the presence of solid surfaces and limited amounts of organic carbon. Therefore, on-site optimization of bioremediation processes requires a comprehensive understanding of biofilm structure, dynamics, and interactions with contaminants and other environmental factors.

Major Characteristics of Biofilms with Importance for Bioremediation

Tolerance towards environmental stressors (e.g., toxic chemicals,
pH change, predation, and dehydration)
Extensive genetic diversification of biofilm bacteria

Extensive genetic diversification of biofilm bacteria
Extensive genetic diversification of biofilm bacteria
Extensive genetic diversification of biofilm bacteria
Communication (quorum sensing) Critical cell density for biofilm formation
Exchange of genetic material Horizontal transfer of genetic material between species, DNA sharing
Metabolic diversity and symbiosis Utilizing waste products and/or accumulated products from the environment or other microorganisms
Redox and electron acceptor diversity Different metabolic functions with respect to electron-acceptor reduction
Varying growth rates in the biofilm Inducing biofilm persistence due to different metabolic states in the biofilm
Porous physical structure with water channels Allow for transport of nutrients, electron acceptors, and waste products
Surfactants Aid in solubilizing hydrophobic or recalcitrant substrates
Microcolony and gradient formation Redox potential and nutrient cycling because of aerobic and anaerobic processes

Examples of Biofilm Applications in Bioremediation

Examples of Biofilm Applications in Bioremediation

In the case of ammonia nitrogen removal, for example, an anaerobic reaction zone is formed on the inner side of the biofilm to grow denitrifying bacteria (anaerobic bacteria), while an aerobic reaction zone is formed on the outer side of the biofilm to grow nitrifying bacteria (aerobic bacteria). The outer side decomposes organic matter into inorganic compounds through aerobic nitrification reactions, while the anaerobic reaction of denitrifying bacteria on the inner side achieves denitrification, converting nitrogen into nitrogen gas and thus completely removing it from the water column. It is this combination of micro-reaction zones that greatly increases the efficiency of biofilm for pollutant removal and facilitates complete reaction.
