EMI Lecture 2019: Prof. Juan Luis Ramos

The double life of Pseudomonas putida: ubiquitous soil bacteria and useful microbial chassis

This year’s Annual Environmental Microbiology lecture, titled ‘The double life of Pseudomonas putida: ubiquitous soil bacteria and useful microbial chassis’ was delivered by Professor Juan Luis Ramos from the Spanish National Research Council (CSIC). Prof. Ramos has been a diligent editor of Environmental Microbiology (since 2007), Environmental Microbiology reports (since its foundation in 2008), and Microbial Biotechnology (since its foundation in 2007) journals. We are delighted to host him for this year’s annual EMI lecture on October 15th.

The lecture began by describing Pseudomonas – a “cosmopolitan” bacterium that is found all over the world. Pseudomonas putida in particular is found in the rhizosphere and is well known for its ability to degrade hydrocarbons and aromatic molecules, which have pushed it into the forefront of the minds of academia and industry alike. Here, Prof. Ramos introduced us to his three main research themes: genomic (and pangenomic) analysis of P. putida strains, P. putida as a model system in agriculture, and P. putida for the production of goods.

In the video you will hear about pangenomic analysis – a way of comparing multiple genomes from similar organisms and finding what they have in common (the ‘core’ genes) and what they have that makes them different (the ‘accessory’ genes), P. putida giving a helping hand to plants, promoting growth, root branching, and outcompeting plant pathogens, and ‘phytorhizoremediation’ – a method of introducing a strain of P. putida which degrades a toxic compound to the seeds of plants, and growing these plants where this compound needs to be removed.
