Abstract: Highlights: [•] VFAs yield was enhanced from digesting rhamnolipid-pretreated waste activated sludge. [•] RL was generated in situ during WAS fermentation. [•] Particulate organics solubilization was improved. [•] The activity of methanogen was inhibited in the presence of RL. [•] Hydrolytic enzymes activity was improved. [Copyright &y& Elsevier]
