Strategic Microbial Discovery in Unique Ecosystems

The research team implemented a sophisticated sampling strategy across diverse Indian locations, focusing particularly on the Ganga River in Kolkata, West Bengal. This location was strategically selected due to its complex microbial ecosystem influenced by industrial effluents, agricultural runoff, and urban pollution—factors that increase the likelihood of discovering novel biosurfactant-producing microorganisms. The team employed rigorous sterile techniques, collecting water samples in sterile polypropylene tubes and maintaining them at 4°C to preserve microbial integrity until processing.

Initial isolation involved serial dilution and plating on nutrient agar, followed by sub-culturing in nutrient broth. The preliminary screening utilized the CTAB-methylene blue agar method, where colonies producing anionic biosurfactants formed distinctive dark blue halos—providing a semi-quantitative measure of biosurfactant production capability., according to industry analysis

AI-Enhanced Medium Optimization and Production

The production medium was carefully formulated to support both microbial growth and biosurfactant synthesis, containing essential minerals, nutrients, and olive oil as the carbon source. What sets this research apart is the integration of artificial intelligence in medium optimization, allowing for unprecedented precision in creating ideal growth conditions. The pure culture flourished at 35°C with 150 rpm rotation over seven days, after which sophisticated extraction and purification processes began.

The extraction protocol involved centrifugation at 10,000 rpm for 20 minutes at 4°C, followed by pH adjustment to 2 using 6N HCl. The biosurfactant was allowed to precipitate overnight at 4°C, maintaining the acidic pH to prevent degradation. Purification employed a carefully constructed solvent system of chloroform and methanol (2:1 ratio), effectively separating the target biosurfactant from water-soluble contaminants in the organic phase., according to recent innovations
