摘要

•A study on lipase-producing yeast Sporidiobolus metaroseus.•The Extracellular Enzymatic Mixture (EEM) of yeast was extracted.•The EEM was characterized through biochemical analyses.•The EEM combined with various gels was applied for removing an overpainting.•The effectiveness of the enzymatic application was evaluated by ATR-FTIR.
