大肠杆菌和枯草芽胞杆菌的原生质体融合

Protoplast Fusion between Escherichia coli and Bacillus subtilis

本文对大肠杆菌 (Escherichiacoli)和枯草芽胞杆菌 (Bacillussubtilis)的原生质体融合进行了研究 ,获得了融合菌原生质体的再生 .根据两种菌的形态和利用淀粉的能力上存在的明显差异 ,对融合菌的原生质体进行筛选 .实验结果表明 ,融合细胞具有降解淀粉的能力 ,但不形成芽胞 .

Protoplast fusion between Escherichia coli and Bacillus subtilis is accomplished.The regeneration and screening of protoplast fusion are conducted according to the different morphology and ability of decomposing starch.The results indicate that the fused cells have the ability of degradating starch but without endospores.
