Heavy metals can have both positive and negative effects on the growth of phosphate solubilizing bacteria (PSB), which are microorganisms that have the ability to solubilize insoluble phosphates, making them available to plants.
Positive effects of heavy metals on PSB growth:
- Enhanced biomass production: Some heavy metals like copper (Cu) and zinc (Zn) can stimulate the growth of PSB by increasing the production of biomass and protein content. This is because these metals can act as micronutrients, playing a crucial role in various cellular processes.
- Increased enzyme activity: Heavy metals like cadmium (Cd) and lead (Pb) can increase the activity of enzymes involved in phosphate solubilization, such as acid phosphatase and alkaline phosphatase. This can enhance the ability of PSB to solubilize phosphates.
- Induced expression of genes: Heavy metals can induce the expression of genes involved in phosphate solubilization, such as the genes encoding for phytase, an enzyme that breaks down phytate, a form of phosphate.
Negative effects of heavy metals on PSB growth:
- Inhibition of growth: High concentrations of heavy metals like mercury (Hg), arsenic (As), and chromium (Cr) can inhibit the growth of PSB by damaging their cell membranes, disrupting their metabolic processes, and altering their gene expression.
- Toxicity: Some heavy metals can be toxic to PSB, leading to cell death or reduced growth rates. For example, high concentrations of Cu can cause oxidative stress and membrane damage in PSB.
- Changes in biofilm formation: Heavy metals can alter the biofilm formation and structure of PSB, which is essential for their survival and phosphate solubilization activities

The National Green Tribunal (NGT) in India has been a crucial instrument in the addressing environmental degradation and pollution-related issues since its establishment in 2010. The NGT was designed to expedite environmental justice, offering a specialized forum for the efficient resolution of environmental disputes. The NGT’s efficacy is evident in its proactive stance on various environmental issues, such as industrial pollution, illegal mining, and deforestation. The Tribunal has passed significant judgments mandating the cleanup of polluted rivers, halting environmentally destructive projects, and imposing fines on violators. Its ability to deliver timely verdicts has often provided swift relief to affected communities, which is critical in preventing irreversible environmental damage. Moreover, the NGT has expanded the scope of environmental jurisprudence in India, emphasizing the principle of sustainable development and reinforcing the “polluter pays ” principle. It has increased accountability by compelling both public and private entities. However, the NGT faces challenges that limit its efficacy. These include limited enforcement power, resource constraints, and occasional conflicts with other judicial bodies. Additionally, the lack of widespread awareness about its role among the general public sometimes hinders access to justice. Despite these challenges, the NGT has played a pivotal role in strengthening environmental governance in India.
