    Isolation and growth optimization of heavy metal resistant bacteria for bioremediation of arsenic
    (UMT Lahore, 2024-10-23) LAIBA SAJJAD
    Arsenic (As) is among the most toxic heavy metals found on earth and is significantly reported as a contaminant from industrial activities. Its release into the environment has led to extreme toxicity to all life forms. This study aims to isolate and characterize arsenic-resistant bacteria from textile industrial wastewater, contributing to bioremediation strategies in heavily polluted areas. Given the increasing concerns about environmental pollution due to industrial activities, particularly in developing countries, the research focuses on identifying bacterial strains capable of surviving in high-arsenic environments. The methodology included sampling wastewater, isolating bacteria, and subjecting the isolates to various biochemical and molecular tests to assess their arsenic resistance. The findings revealed that certain bacterial strains exhibited significant arsenic resistance, indicating their potential for application in bioremediation processes. These strains were also able to tolerate varying levels of salinity, suggesting their adaptability to diverse environmental conditions. The study’s results highlight the importance of utilizing indigenous bacterial strains for environmental cleanup in industrial regions, particularly in countries like Pakistan, where textile industries are a significant source of pollution. In the future, these isolates can be taken towards molecular characterization followed by field experiments.
