Use of Ecoplates in Soil Polluted with Heavy Metals

Abstract

Global concern revolves around the persistent attributes of harmful non-biodegradable contaminants, especially heavy metals and metalloids, which draws attention to environmental pollution. As regards to soil ecosystem, microorganisms have a significant impact on heavy metal concentrations, either actively or passively. Heavy metal toxicity profoundly impacts the metabolic activities of microbial communities, leading to disruptions in essential cellular processes. Heavy metals interfere with the enzymatic reactions necessary for energy of metabolism, nutrient cycling, and organic matter degradation, resulting in reduced microbial growth and activity. The Biolog Ecoplate method is used as an effective tool for assessing microbial activity. The potential use of Biolog Ecoplate in the study of microbial community structure and diversity in heavy metal-polluted soil was investigated. In order to achieve this goal, multiple keywords combinations were used to filter the most important results in the field. In metal-contaminated soils, the use of Biolog Ecoplate has led to notable changes in microbial community composition, marked by increased populations of resistant and metal-reducing microorganisms.
