Microbial Strategies for Industrial Waste Bioremediation

Abstract

Rapid industrialization has accelerated economic growth but also increased hazardous industrial wastes that threaten environmental sustainability and public health. Mining, paint, and detergent industries release pollutants such as heavy metals, dyes, surfactants, volatile organic compounds, and acid-forming substances. Conventional physicochemical treatment methods are often costly, energy-intensive, and may generate secondary pollution, creating the need for eco-friendly alternatives. This chapter examines the characteristics, environmental fate, and health effects of wastes from these industries while highlighting microbial remediation strategies. Techniques including biosorption, bioaccumulation, bioprecipitation, bioleaching, biomineralization, bioaugmentation, and biostimulation are discussed for heavy metal removal and degradation of organic pollutants. Emerging technologies such as microbial fuel cells, nano-bioremediation, and genetic engineering are also explored for improving treatment efficiency and supporting resource recovery.
