Description :
Many metals are essential for life can be harmful to humans, animals, plants, and microorganisms when present at toxic levels. The occurrence of heavy metals in soil is primarily attributed to industrial, mining, and agricultural activities. This study focuses on isolating soil microbial populations from heavy metal-contaminated soil and determining the minimum inhibitory concentration (MIC) of heavy metals against bacterial populations collected from a metal industry site. Heavy metal contamination in soil poses a significant environmental challenge. The microbial community identified in the study comprised two groups: heavy metal-resistant and sensitive populations. The resistant microbial isolates included species such as Pseudomonas, Bacillus, Corynebacterium, and Micrococcus. The MIC of the isolates was evaluated for metals like cadmium (Cd), chromium (Cr), nickel (Ni), and lead (Pb) in soil media. The isolated heavy metal bacteria could be effective and useful for the bioremediation of heavy metal contaminated soil.
