intro

The problem of environmental pollution generated by the massive use of plastic materials derived from the petrochemical industry has attracted much interest in the implementation of sustainable processes, involving the use of biomass derived from waste to generate alternative materials (bioplastics) to these high consumption products. Although our projects involve several polymers of biotechnological interest like bacterial nanocellulose, many of our research activities focus on the production of bacterial polyesters or polyhydroxyalkanoates (PHA), which are considered one of the most promising bioplastics due to their biodegradable character. Our designs are based on the use of industrial and urban biowastes such as glycerol, fatty residues or synthetic gas (syngas) as sources for the bacterial fermentation. Both natural-producing bacteria, such as Pseudomonas putida and Rhodospirillum rubrum, as well as genetically optimized microorganisms, are considered in these processes. We invest our effort in studying the metabolic and regulatory networks in producing microorganisms and others sharing their natural environment such as predatory bacteria like Bdellovibrio bacteriovorus. We apply our findings in the production of new materials including the second generation functionalized PHA with new properties (e.g. anti-microbial), and susceptible to chemical modification after its biosynthesis. In addition, we are very interested in the design and development of new downstream systems to process the bacterial biomass for the separation of intracellular bioproducts. In this aspect, we use different strategies to control the release of bioproducts to the extracellular medium as controlled self-cell-disruption systems based on the production of lytic proteins in the producer microorganism. Finally, we are working on the identification and characterization of enzymes for synthesis and biodegradation of materials, as well as the production of building blocks as monomers for polymer synthesis.
