摘　　要：为研究不同细菌对尾草履虫种群增长的影响,通过向稻草培养液中添加大肠杆菌、枯草芽孢杆菌、蜡样芽胞杆菌及金黄色葡萄球菌喂饲尾草履虫,结果表明:大肠杆菌最有利于尾草履虫种群的增长及稳定,金黄色葡萄球菌对尾草履虫增殖有抑制作用,蜡样芽胞杆菌对尾草履虫早期增殖最为迅速,枯草芽孢杆菌对尾草履虫接合生殖地发生有促进作用。This experiment studies the different bacteria in feeding paramecium caudatum by adding escherichia coli,bacillus subtilis,bacillus cereus,staphylococcus aureus in the mediums.The results show that escherichia coli is the most conducive bacteria to the growth and stability of mediums population,while staphylococcus aureus has inhibitory effect on paramecium caudatum proliferation,bacillus cereus is the most helpful to the early stage of paramecium caudatum proliferation,and bacillus subtilis could facilitate the happening of zygogamy of paramecium caudatum.
