Stability is provided by the lipid part of the biosurfactant. I am not sure whether all lipopetides and glycolipids are stable at 100 C . I have experience where you time profile for stability.

Jyotsna mam, ya I am talking about the emulsification and surface tension reducing stability of biosurfactant at 100 degree celcius.

Thanks Randir S Makkar Sir for the answer.

And I have also read your research "Biosurfactant production by a thermophilic Bacillus subtilis strain" which depicts the stability of biosurfactants surface-active properties after heating at 100°C for 2 h.
