2The protoplast formation and regeneration and fusion conditions of strain ISW330 and AS 1.495 were studied in this thesis. One L-isoleucine high-producing strain SW0370 was screened through protoplast fusion, shake flask screening, genetic marker test and single clone isolation and continuous cultivation for generations.
