A novel yeast-binding lectin from hemolymph Cyclina sinensis (Gmelin) and its effects on yeast cells

► A novel yeast-binding lectin was purified from hemolymph Cyclina sinensis (CSL). ► The carbohydrate-specificity of CSL showed that it is belong to new mannose-specific lectin. ► SDS-PAGE showed that the CSL protein had a molecular mass of 72 kDa, and consisted of 40 and 18 kDa subunits. ► CSL reveals to be a stimulator of Saccharomyces cerevisiae ethanol production.
