Abstract

Background: Corn steep liquor (CSL) is a rich source of bioactive compounds, particularly biosurfactants. In this work, two biosurfactant extracts were produced successfully at a pilot scale using CSL. One was more hydrophobic and was obtained through liquid-liquid extraction with ethyl acetate (BS-ACT). The other was more hydrophilic, obtained through solid-liquid extraction with phosphate buffer saline (PBS) (BS-PBS).

Results: The biosurfactant extracts (BS-ACT and BS-PBS) were included in biocide formulations to assess their impact on enhancing the suspensibility and solubility of different metallic active substances. The BS-PBS extract exhibited superior properties in suspending biocides in comparison with BS-ACT, despite BS-ACT demonstrating a higher solubility capacity. Moreover, in comparison with chemical surfactants, BS-ACT displayed significantly greater ability to solubilize biocides in water, whereas BS-PBS showed suspensibility results that were comparable with synthetic surfactants.

Conclusion: Biosurfactant extracts derived from CSL act as coadjutants in metallic biocide formulations, enhancing their dissolution or suspension in water and providing a sustainable alternative to chemical surfactants. © 2025 Society of Chemical Industry.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
