WHY IS BACTERIA PREFFERRED?

par Thejaswini H,

I lean toward bacteria because they grow rapidly, adapt easily to polluted environments, and can be genetically and metabolically versatile. Pseudomonas putida is especially well known for its ability to degrade hydrocarbons, solvents, and aromatic compounds by using them as a carbon and energy source. This makes it very effective in breaking down toxic organic pollutants into less harmful substances.

Compared to fungi or algae, bacteria like P. putida act faster, are easier to culture and apply in situ, and work well in contaminated soils and wastewater systems. Its proven use in bioremediation studies and environmental safety record strongly influence my choice.

WHY IS BACTERIA PREFFERRED?

par Thejaswini H,
I would choose a bacterium, Pseudomonas putida, to address local environmental pollution such as contaminated soil or wastewater because of its high metabolic versatility and adaptability. This bacterium can degrade a wide range of toxic organic pollutants, including hydrocarbons, solvents, and pesticides, by using them as energy sources. It survives well under harsh environmental conditions like fluctuating pH, temperature, and pollutant load, which are common at polluted sites. Its ability to form biofilms enhances contact with contaminants, increasing degradation efficiency. Moreover, Pseudomonas putida is non-pathogenic and environmentally safe, making it suitable for field applications without disturbing native ecosystems. Its rapid growth, cost-effectiveness, and well-studied genetics further support its selection for bioremediation purposes.

WHY IS BACTERIA PREFFERRED?

par Thejaswini H,
I would choose microalgae, particularly Chlorella vulgaris, to address local environmental issues such as nutrient-rich wastewater and heavy metal contamination. I lean toward algae because they combine bioremediation with ecological restoration. Chlorella efficiently absorbs nitrates, phosphates, and heavy metals like cadmium and lead while performing photosynthesis, thereby reducing eutrophication and improving water quality. Unlike bacteria, algae also produce oxygen, which supports aerobic microorganisms and overall ecosystem health. Additionally, algal biomass generated during remediation can be harvested and reused for biofertilizers or biofuel production, making the process sustainable and economically attractive. This dual role of pollution removal and resource recovery makes microalgae a compelling alternative for environmental cleanup.
