The inevitable impacts by the emerging urbans developments towards the quality and function of soil have raised concerns for future environment consequences. Pollutants that evolved from the anthropogenic activities including heavy metals, pesticides, petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs) tend to be persistent within the soil and hence, contribute to long term effects towards the environment and human’s health. Bioaugmentation method as bioremediation approach is a promising strategy to rectify this issue by introducing specific microorganism (i.e., bacteria or fungi) to degrade or eliminate targeted pollutants. This paper presents the concept and method of bioaugmentation by describing step-by-step method as a guidance to implement this method. The identification and selection of microorganism is a crucial element to assure the success of bioaugmentation. Additionally, there are few factors that influence the efficiency of bioaugmentation which include pH, temperature, moisture and type and intensity of the pollutants. The applications of bioaugmentation towards different types of pollutants as stated in this works have certified its capability of degrading, removing, and transforming pollutants into less toxic components. This review extensively focusses to recognize and understand the concept, the step-by-step method, and comparative studies of bioaugmentation towards different pollutants which are heavy metals, pesticides, petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs). For future prospect, bioaugmentation method can be improved and enhanced by employing new and advanced strategy to tackle the pollutants in a long term. © 2024 Penerbit UTM Press. All rights reserved.
