- Extremophile Studies: Conducted extensive research on extremophiles from deserts, hot springs, and volcanic lakes, with pioneering work on Chroococcidiopsis from Antarctic endoliths, a cyanobacterium surviving in extreme conditions where no other life thrives.
- Discovery of Phosphorus and Nitrogen Metabolic Pathways: Provided first reports of phosphorus and nitrogen metabolic pathways in cryptoendoliths, offering insight into the growth of algae in harsh environments at the limits of life.
- Phylogenetic Analysis of Algae: Performed a detailed phylogenetic analysis of algae from Yellowstone hot springs, Greenland, and Iceland’s volcanic lakes, proposing a common lineage despite geographic separation.
- Bioremediation of Heavy Metals and Oils: Explored how cyanobacteria can mitigate heavy metal and oil contamination in aquatic and terrestrial environments, emphasizing their potential for environmental cleanup.
- Phosphatase Enzyme Role in Phosphorus Dynamics: Elucidated the role of phosphatase enzymes in phosphorus dynamics in Leptolyngbya species isolated from volcanic lakes and hot springs.
- Wastewater Treatment and Frac Fluid Cleanup: Developed efficient methods for treating municipal wastewater and cleaning frac return fluids using algae. The harvested algal biomass has multiple uses, including fertilizer, animal feed, paint production, and even biofuel and electricity generation.
Future Applications of Algal Research
What the world needs today is awareness to reduce the use and exploitation of the environment and nature, emphasizes Dr. Meenakshi. The future lies in adopting green technologies across all sectors as quickly as possible, moving away from traditional methods. Algae can be leveraged across numerous sectors to achieve a sustainable future:
- Healthcare: Algae-derived products such as Omega-3, Astaxanthin, single-cell proteins, and bioactive compounds—including antibiotics, antivirals, and anticancer drugs—offer eco-friendly, plant-based solutions that could revolutionize the industry.
- Agriculture: is on the brink of a green revolution, with the widespread use of biofertilizers, biopesticides, bioinsecticides, and bioherbicides poised to mitigate the harmful effects of chemical farming.
