一个由纽卡斯尔大学(英国)的几个学院的学生们组成的研究小组已经开发出了一种新型细菌,可产生一种坚实的基质以用来填补混凝土裂缝。这是一种含有钙、糖和细菌的营养混合物解决方案,可以应用于侵蚀和破碎的混凝土,细菌会在低pH值环境下激活,当细菌涌入混凝土缝隙中,因为细菌开始结块或者是所谓的群体感应,它们到达缝隙底部时可以感知。 A team of students from several colleges at Newcastle University (UK) has developed a new type of bacteria that produces a solid matrix that can be used to fill concrete cracks. This is a nutrient mixture solution containing calcium, sugar and bacteria that can be applied to eroded and crushed concrete. Bacteria activate at low pH. As bacteria intrude into concrete gaps because bacteria begin to cake or The so-called group sensing, they reach the bottom of the gap can be perceived.
