報告摘要🧖🏻‍♂️：

Motile bacteria have the ability to“sample”their environment and detect and move toward available growth substrates using a process called chemotaxis. Many soil bacteria are capable of degrading a wide variety of organic compounds including toxic pollutants and man-made chemicals. Chemotaxis can increase the efficiency of the biodegradation process. The most common sensory proteins used for bacterial chemotaxis are cell-surface receptors called methyl-accepting chemotaxis proteins, and the genomes of soil bacteria often harbor up to 60 chemoreceptor genes. P. putida is chemotactic to most substrates on which it is capable of growth, and it uses several different strategies to detect potential growth substrates. In this presentation it will be described and discussed that the different types of metabolism-dependent and metabolism-independent responses used by P. putida to locate potential sources of carbon, nitrogen, and energy in its environment.
