Key Points

To explore how biosurfactants affect the desorption of heavy oil from different mineral substrates through experimental and simulation methods.
Integrated molecular dynamics simulations with bench-scale experiments
Investigated adsorption and desorption on five mineral substrates: SiO2, kaolinite, muscovite, Ca2+-montmorillonite, Na+-montmorillonite
Assessed microbial dynamics alongside heavy oil contamination
Biosurfactants effectively enhanced desorption of heavy oil from mineral substrates
Differences in desorption rates were observed among the five types of substrates
Molecular simulations supported experimental findings, providing insights into adsorption and desorption mechanisms.
