报告摘要：

Prof. Andrew W.B. Johnston got a PhD in the Institute of Animal Genetics in Edinburgh University in the late 1960's, before going to the John Innes Institute (as it was called then) as a post-doc in 1973. At the John Innes, he worked as a research scientist in Sir David Hopwood's Genetics department till 1989. During that time, he analysed the nitrogen-fixing symbiotic bacterium Rhizobium, helping to develop molecular and classical genetic methods to identify the genes that allowed the bacterium to form nodules and to fix N2 in the nodules of legume plants.

In 1989, he joined in the University of East Anglia as a professor in the School of Biological Sciences, still working on Rhizobium but now concentrating on how these bacteria acquired and responded to transition metals, mainly iron and manganese. He then developed an increasing interest in microbial ecology and metagenomics. Since 2007, his main focus has been on how marine bacteria can catabolise a little-known, but very important sulfur-containing molecule called dimethylsulfoniopropionate (DMSP), which is made in huge amounts by marine algae and plankton. He has published more than 150 papers in environmental microbiology and molecular biology.
