The protoplast fusion is an important process in the genome shuffling. In order to improve the efficiency of the genome shuffling and the CoQ₁₀ production, this paper studies the conditions of the protoplast preparation and the regeneration of CoQ₁₀ to produce the strain Rhodobacter sphaeroides. The parameters of the proper protoplast formation and the regeneration were determined through the growth curve and the orthogonal experiment: the lysozyme concentration is 1mg/ml, the enzymatic temperature is 37℃; the enzymatic time is 1h and the sucrose concentration is 10%, and under these conditions, the protoplast formation rate is 96.1% and the protoplast regeneration rate reaches 28.8%. Therefore, the optimized conditions of the protoplast preparation and the regeneration for the genome shuffling of Rhodobacter sphaeroides are obtained., authors=SONG Liya¹, QIAO Zhixin², LI Weijing², HE Min², ZHAO Hua¹, YU Qun², authorsList=SONG Liya;QIAO Zhixin;LI Weijing;HE Min;ZHAO Hua;YU Qun, authorCompany=1.
