Electro-spun silk fibroin (SF) has attracted researcher's attentions due to its good cyto-compatibility and excellent performance as a tissue engineering scaffold. Although it was reported silkworm variety affected molecular weight (MW) and solution viscosity of silk fibroin, the effect of silkworm variety on the electro-spinning performance of silk fibroin has not been studied, yet. In the present study, the regenerated SF with five different silkworm varieties was used in electro-spinning and the effect of silkworm variety on the electro-spinning of silk fibroin performance was examined. It was turned out that silkworm variety strongly influenced electro-spinning rate and diameter of electro-spun fiber. Geumgwangju and Wonwon126 showed the highest and the lowest electro-spinning rate and fiber diameter. �-sheet crystallization of electro-spun SF fibers took place partially and silkworm variety almost did not effect crystallization of SF.
