JAVIER LLAMA
Javier Llama obtained his bachelor's degree in biology from Universidad Complutense de Madrid, where he developed a strong foundation in microbiology, biochemistry, molecular biology and environmental sciences. He later completed a master's degree in microbiology at Universidad Complutense de Madrid, further specializing in microbial physiology, metabolic diversity and applied microbiology.
He is currently a predoctoral researcher working under a research contract within the framework of the BIVALIA project, focused on circular economy strategies and the treatment and valorization of bio-waste. His PhD research centers on the use of purple phototrophic bacteria (PPB) for the sustainable treatment of industrial residues, integrating wastewater remediation with the recovery of high value bioproducts.
His work explores the metabolic versatility of PPB under anaerobic photoheterotrophic conditions to simultaneously remove organic load and transform waste streams into resources. In particular, he investigates the production of single-cell protein (SCP) as a sustainable alternative for feed and food applications, as well as the biosynthesis and modulation of carotenoids with potential antioxidant and nutraceutical interest. Additional research lines include the cultivation of PPB using syngas as a carbon and energy source to produce biomass and other high value bioproducts of industrial relevance.
His research combines microbiology, photobioreactor design and operation, and process optimization to maximize biomass productivity and resource recovery efficiency. He also applies advanced analytical techniques for pigment identification and quantification, alongside mathematical modeling of microbial growth and process performance. Through this integrated approach, his work contributes to the development of robust biotechnological platforms that align wastewater treatment with the generation of commercially valuable products, reinforcing the principles of circular economy and environmental sustainability.
