Bioremediation – Our research focuses on development of indigenous microbial consortia to break down pollutants such as petroleum hydrocarbons, pesticides, and other xenobiotic compounds in the environment. These microbial processes contribute to environmental cleanup and sustainable waste management. We have developed a metabolically efficient microbial consortium for petroleum hydrocarbon and xenobiotic degradation in both aquatic and terrestrial environments. This approach leverages microbial biosurfactant-mediated degradation and utilizes an indigenous consortium isolated from marine environments.
Biofertilizers – We develop microbial biofertilizers using beneficial fungi such as Trichoderma, mycorrhizal fungi, and plant endophytes. These enhance soil fertility, improve plant growth, and reduce reliance on chemical fertilizers, promoting sustainable agriculture.
Microbial & Enzyme Degradation of Synthetic Plastics –Biodegradation of Petroleum-Based Synthetic Plastics
Globally, 31.9 million metric tons of plastic waste accumulate annually, with 1.59 million metric tons in Sri Lanka alone—much of it reaching the ocean. The widespread release of microplastics contaminates marine ecosystems, posing risks to wildlife and human health through ingestion.
We focus on identifying and characterizing indigenous microbial strains and depolymerases capable of breaking down petroleum-derived synthetic plastics. These microbes and enzymes are explored for bio-augmentation and bio-stimulation strategies to enhance the bioremediation of plastic-polluted environments.
Microbial Secondary Metabolites – We investigate the production of high-value microbial metabolites such as biosurfactants and pyocyanin for industrial, pharmaceutical, and environmental applications. Currently, our lab focuses on the production of biosurfactants using waste coconut oil as a sustainable raw material. These biosurfactants have potential applications in bioremediation, detergents, and pharmaceutical formulations.
Pyocyanin, a bioactive pigment produced by Pseudomonas spp., is studied for its antimicrobial properties. We explore its potential as an alternative to conventional antibiotics and its role in inhibiting pathogenic microorganisms.
Industrial Enzymes & Biocatalysts – We study microbial enzymes such as depolymerases, lipases, and laccases for their role in industrial biocatalysis, biodegradation, and biotransformation. These enzymes have applications in waste management, biofuel production, textile processing, and pharmaceutical industries.
Precision Agriculture with AI Integration (Collaboration) – We explore the integration of microbial solutions with AI-driven precision agriculture to optimize crop health, improve yields, and enhance resource efficiency.
