Introduction Phytoremediation is a type of bioremediation in which plants are used to degrade or absorb contaminants to render soil, water, or air harmless. It also involves microbial activities to assist plants in remediating the pollutants. It has many advantages i.e. cost effective, involves little manpower, is aesthetically pleasing, accepted by surrounding residents. In this … Read more
Introduction Bioremediation techniques have become increasingly effective in restoring polluted environments, making them more cost-effective and sustainable. These techniques involve the use of indigenous and non-indigenous bacteria, which are already present in polluted environments. These microorganisms detoxify, reduce, degrade, mineralize, or transform toxic pollutants into less toxic and stable forms. The efficiency of the process … Read more
Introduction Global industrialization is causing significant harm to life forms due to the release of pollutants like oil hydrocarbons, heavy metals, and pesticides. Remediation of contaminated sites is essential for environmental preservation and urban development. Soil remediation methods include chemical, physical, and biological methods. Bio-processes such as phyto and bioremediation are mostly used as they … Read more
There are different factors which affect the ability of microorganisms to bioremediate heavy metals such as total metal ion concentration, soil structure, moisture content, temprature, pH, solubility of heavy metals in water any many more. Some of the factors affecting microbial bioremediation are discussed below. Factors affecting microbial bioremediation 1: pH Different microbes prefer different … Read more
Urbanization and industrialization have led to the release of numerous toxic pollutants into the environment, including heavy metals from industrial processes and wastewater. These pollutants include antimony, chromium, mercury, aluminium, copper, zinc, nickel, lead, and arsenic. Untreated pollutants from wastewater, from agri-food industries and crude oil also contribute to environmental pollution. Mining processes release toxic … Read more
