Bio-Based Biosurfactant Developed in North-East India: A Sustainable Alternative for Cosmetic Industry

 



Bio-Based Biosurfactant Developed in North-East India: A Sustainable Alternative for Cosmetic Industry

Background

Modern industries such as cosmetics, pharmaceuticals, detergents, and food processing rely heavily on synthetic surfactants. These chemical compounds act as lubricants, emulsifiers, and dispersing agents, helping oil and water mix effectively in products such as face washes, shampoos, creams, and lotions.

However, conventional surfactants are largely derived from petrochemical sources and often pose environmental and health concerns. Many synthetic surfactants are non-biodegradable, toxic to aquatic ecosystems, and potentially irritating to human skin.

With increasing awareness of green chemistry and sustainable manufacturing, scientists around the world are searching for bio-based alternatives that are biodegradable, environmentally friendly, and compatible with biological systems.

In this direction, researchers from the Institute of Advanced Study in Science and Technology (IASST), an autonomous institute under the Department of Science and Technology (DST) in North-East India have achieved a significant breakthrough by synthesizing a novel biosurfactant using natural biological processes.

Introduction

A team led by Prof. Ashis K. Mukherjee, Director of IASST, along with Prof. M. R. Khan and Ms. Anushree Roy, developed a lipopeptide biosurfactant using the probiotic bacterium Lactobacillus plantarum JBC5.

The researchers used ghee, a traditional dairy product widely used in Indian households, as a lipid-rich substrate to support microbial synthesis.

Through a carefully optimized fermentation process and response surface statistical analysis, the team achieved maximum biosurfactant production with high functional efficiency.

The biosurfactant demonstrated remarkable properties:

  • Strong antibacterial activity, especially against Staphylococcus aureus, a bacterium responsible for skin infections and wound contamination.

  • Excellent emulsification capacity (about 60%) for edible oils.

  • High stability across wide pH ranges and extreme temperatures up to 276°C.

  • Enhanced cleansing efficiency when combined with commercial cosmetic products such as face washes.

These characteristics make the compound a promising replacement for artificial surfactants in cosmetic and pharmaceutical formulations.

Objective of the Research

The primary objectives of this scientific initiative include:

  1. Developing sustainable bio-based surfactants that can replace synthetic chemical surfactants in industrial applications.

  2. Utilizing natural and culturally relevant substrates, such as ghee, for microbial biosynthesis.

  3. Improving product safety by reducing the use of harmful petrochemical compounds in cosmetics and medicines.

  4. Exploring antibacterial applications, particularly against pathogens responsible for skin infections.

  5. Promoting green biotechnology innovations emerging from North-East India.

Substances and Biological Sources Used for Synthesis

The biosurfactant was synthesized using a microbial fermentation process involving natural substrates and probiotic bacteria.

Component

Role in Synthesis

Source

Lactobacillus plantarum JBC5

Microorganism responsible for biosurfactant production

Probiotic bacterium

Ghee (Clarified Butter)

Lipid-rich carbon substrate used for microbial metabolism

Dairy product

Fermentation Medium

Supports bacterial growth and biosurfactant secretion

Nutrient broth containing salts and nutrients

Statistical Optimization (Response Surface Analysis)

Improves yield and efficiency of biosurfactant production

Analytical technique

This approach highlights a biotechnology-driven synthesis pathway that relies on renewable biological inputs rather than petroleum-based chemicals.

Impact of the Innovation

1. Environmental Sustainability

Bio-based surfactants are biodegradable and eco-friendly, reducing environmental pollution caused by synthetic surfactants.

2. Safer Cosmetic Products

The compound’s antibacterial and cleansing properties make it suitable for skin-friendly cosmetic formulations, potentially reducing irritation and toxicity.

3. Pharmaceutical Applications

Because it inhibits Staphylococcus aureus, the biosurfactant could contribute to wound care products and antibacterial topical formulations.

4. Strengthening Indigenous Biotechnology

The research demonstrates how local biological resources and traditional substances like ghee can be integrated with modern biotechnology to create innovative industrial solutions.

5. Industrial Commercialization Potential

Researchers are currently conducting:

  • Toxicity assessments

  • Dose standardization

  • Industry collaborations

These steps aim to accelerate commercial production and large-scale adoption of the compound in cosmetics and medicine.

Conclusion

The synthesis of a novel biosurfactant by IASST scientists marks an important milestone in India’s pursuit of sustainable and bio-based industrial chemistry. By combining probiotic microbial technology with natural substrates like ghee, the research offers a promising solution to replace environmentally harmful synthetic surfactants.

As further studies and industrial collaborations progress, this innovation could transform the cosmetic and pharmaceutical sectors, while also strengthening India's green biotechnology ecosystem and indigenous scientific research capabilities.
