Desarrollo de herramientas biotecnológicas en cianobacterias.Development of biotechnological tools in cyanobacteria

Resum

Cyanobacteria are among the oldest living organisms on the planet, and they can be found in every ecosystem on Earth, from freshwater oceans, rivers and lakes to hot springs and deserts. Apart from their ecological role in the global carbon and nitrogen cycles, cyanobacteria are becoming an increasingly attractive chassis in the biotechnological production of high value-added compounds since the requirements for their growth, light, and CO2, are minimal, costless, and abundant.Although various cyanobacteria, notably Synechocystis spp. and Synechococcus spp., have already been characterized for their industrial application, many of them grow in very specific conditions, mainly under controlled laboratory conditions. For this reason, new cyanobacteria that can be used as chassis or provide genes of interest in biotechnology are continually being sought. Therefore, it is important to study the diversity of cyanobacteria in order to develop their potential for human benefit. On the other hand, as molecular tools available to modify the metabolism of cyanobacteria are still limited compared to those described for other industrially or biotechnologically-used microorganisms, there is a need for developing new and more versatile biotechnological tools for them...
