Bioremediation of Solid and Liquid Wastes

The study focuses on the analysis of wastewater and river water from 40 sites in Uttarakhand, revealing that wastewater exceeded acceptable limits for various parameters set by health organizations. Heavy metal concentrations were assessed in both solid and liquid waste, identifying eight samples with the highest levels for further bioremediation research. Microbes were isolated and characterized, with seven selected for their ability to grow in heavy metal-amended media. Notably, gram-positive bacteria emerged as effective bioadsorbents for heavy metal removal.
