چکیده
Remediation states for the removal of pollutants from the environment. Remediation can be done in various ways such as by using waste biomass for sorption of pollutants or by living organisms like plants, microbes that cause degradation of pollutants. Bioremediation implies the use of microbes in the removal of heavy metals, industrial wastes and any other type of toxic wastes from the environment. These microbes may be used in viable and non-viable form, natural and modified form. Microbes used in natural form, faced many challenges related to their survival and tolerance to harsh environmental conditions.

متن کاملNew Approaches for Bioaugmentation as a Remediation Technology
Bioaugmentation is commonly employed as a remediation technology. However, numerous studies indicate that introduced microorganisms often do not survive in the environment and thus do not increase contaminant remediation. This review details several new approaches that may increase the persistence and activity of exogenous microorganisms and/or genes following introduction into the environment....
متن کاملCognitive remediation improves cognition and good cognitive performance increases time to relapse – results of a 5 year catamnestic study in schizophrenia patients
BACKGROUND Cognitive deficits are stable features of schizophrenia that are linked to functional outcome.
