Deciphering supramolecular arrangements, micellization patterns, and antimicrobial potential of bacterial rhamnolipids under extreme treatments of temperature and electrolyte.

The micellization properties of rhamnolipids (RLs) in extreme electrolyte concentrations and temperatures have gained considerable attention due to their broad industrial applications. In this study, the aggregation behavior, specifically the micellization pattern (critical micelle concentration (CMC)) of RLs produced from a newly isolated thermophilic strain of from a harsh environment of an oil field, was investigated by a spectrophotometric method at various temperatures (293-393 K) and electrolyte concentrations (NaCl: 2-20%). The result indicated that the values (0.
