Fast growing human civilization and industrialization have resulted in increased amounts of pollutants such as pesticides, electronic wastes, etc. in the environment. These pollutants have hazardous impacts on living organisms including human health. Remediation of these contaminants is a serious environmental issue of current interest. Recent research has shown that soil microorganisms play an important role in remediating and improving disturbed ecosystems. This approach is ecofriendly and relatively less expensive. The investigations carried out using microbes for restoration of degraded eco-systems is covered in the proposed book. Table of Contents 1.
