英《新科学家》第88卷第1224期(1980)年报道: 细菌的驱化性是能够在外环境中对化学诱引剂或驱逐剂反应,移向有它们所喜欢的某种高浓度物质的区域,或离开有它们所不喜欢的某种高浓度物质的区域。使诱引剂或驱逐剂与细菌的受体部位结合,从而产生细菌游泳行为改变的细胞内的信号是什么,尚一直不清楚。现在美国威斯康星大学生化系和遗传系的布莱克(Roy Black),霍布森(Ann Hobson)和艾德勒(Julius Adler)认为他们已经证 British New Scientist, Vol. 88, No. 1224 (1980) reported that the driveability of bacteria is the ability to react with chemoattractives or de-agents in the outer environment to some of the high concentrations they like Areas, or areas that leave some sort of highly concentrated material they do not like. It remains unclear what the intracellular signal that causes the attractant or the de-agent to bind to the receptor site of bacteria to produce altered bacterial behavior in swimming. Now Roy Black, Ann Hobson and Julius Adler of the Department of Biochemistry and Genetics at the University of Wisconsin believe they have been certified
