Surfactants are extensively used across industries as lubricants, dispersants, and emulsifiers. However, synthetic surfactants often raise concerns regarding toxicity and environmental persistence. The newly synthesised biosurfactant addresses these issues by offering a biodegradable and potentially safer alternative.
The study was led by Prof. Ashis K. Mukherjee, Director of IASST, along with Prof. M. R. Khan and Senior Research Fellow Ms. Anushree Roy. The team employed the probiotic bacterium Lactobacillus plantarum JBC5 and used ghee a culturally significant and lipid-rich dairy product as a novel substrate for production.
Scientific Innovation and Optimisation
The biosurfactant was synthesised using advanced response surface statistical analysis to optimise production. The resulting lipopeptide compound achieved a maximum emulsification index of 60 percent for edible oils and effectively reduced surface tension, comparable to conventional surfactants.
Notably, the compound demonstrated exceptional stability at temperatures up to 276°C and across a wide range of pH levels. Such stability enhances its suitability for diverse industrial and cosmetic applications.
Antibacterial and Cleansing Benefits
Laboratory studies revealed that the biosurfactant acts effectively against Staphylococcus aureus, a bacterium commonly associated with skin and wound infections. When blended with commercially available face washes, the compound significantly enhanced stain removal efficiency.
These properties highlight its potential for use in cosmetic formulations, skincare products, and even certain medicinal applications. By substituting synthetic surfactants, the innovation may reduce environmental impact and improve consumer safety.
Path Towards Commercialisation
The researchers are currently conducting further toxicity evaluations and dose standardisation studies to ensure safety and regulatory compliance. Collaborative industry-driven research is also underway to accelerate commercial adoption of the biosurfactant.
Strengthening India’s Bioeconomy
The development aligns with India’s broader push toward sustainable innovation and bioeconomy growth. By leveraging indigenous resources and advanced biotechnology, the IASST team has demonstrated how traditional substrates like ghee can support modern scientific breakthroughs.
If successfully commercialised, the biosurfactant could mark a shift in the cosmetic and pharmaceutical sectors toward greener, safer alternatives reinforcing India’s position in sustainable scientific research.
