Biotransformation of poly(cis-1,4-isoprene) in a multiphase enzymatic reactor for continuous extraction of oligo-isoprenoid molecules
Andler-Osorio, Rodrigo; Valdés, Cristian; Díaz-Barrera, Álvaro; Steinbüchel, A. (2020)Biotechnological processes for the partial degradation or transformation of poly(cis-1,4-isoprene) rubber have been investigated during recent decades with promising results. The use of the enzyme ‘latex clearing protein’ ...

Coenzyme Q production by metabolic engineered Escherichia coli strains in defined medium
Martínez, Irene; Zelada, Patricio; Guevara, Felipe; Andler-Osorio, Rodrigo; Urtuvia, Viviana; Pacheco-Leyva, Ivette; Díaz-Barrera, Álvaro (2019)Coenzyme Q (CoQ) plays an important role as an electron transporter in the respiratory chain. It is formed from a benzoquinone ring and an isoprenoid chain of a specific length depending on the organism. We constructed an ...

Current progress on the biodegradation of synthetic plastics: from fundamentals to biotechnological applications.
Andler-Osorio, Rodrigo; Tiso, Till; Blank, Lars; Andreeßen, Christina; Zampolli, Jessica; D'Afonseca, Vívian; Guajardo, Camila; Díaz-Barrera, Álvaro (2022)Plastic pollution is a global concern due to the long half-life and high resistance of many synthetic plastics to natural biodegradation. Therefore, great effort is required to avoid littering. However, the challenge of ...

Efficient production of a polyhydroxyalkanoate by Azotobacter vinelandii OP using apple residues as promising feedstock
Andler-Osorio, Rodrigo; Rojas, Victoria; Pino, Valentina; Castro, Ricardo I.; Valdés, Cristian; Kumar, Vinay; Peña, Carlos; Díaz-Barrera, Álvaro (2023)Fruit residues are attractive substrates for the production of bacterial polyhydroxyalkanoates due to the high contents of fermentable sugars and the fast, simple, and efficient pretreatment methods required. In this study, ...

Fruit residues as a sustainable feedstock for the production of bacterial polyhydroxyalkanoates
Andler-Osorio, Rodrigo; Valdés, Cristian; Urtuvia, Viviana; Andreeßenb, C.; Díaz-Barrera, Álvaro (2021)Polyhydroxyalkanoates (PHA) are bio-based and compostable polyesters while at the same time exhibiting physical and mechanical properties similar to conventional fossil-based plastic materials. To make the biotechnical ...

Molecular weight and guluronic/mannuronic ratio of alginate produced by Azotobacter vinelandii at two bioreactor scales under diazotrophic conditions
Díaz-Barrera, Álvaro; Sánchez-Rosales, Francisco; Padilla-Córdova, Claudio; Andler-Osorio, Rodrigo; Peña, Carlos (2021)Alginates can be used to elaborate hydrogels, and their properties depend on the molecular weight (MW) and the guluronic (G) and mannuronic (M) composition. In this study, the MW and G/M ratio were evaluated in cultures ...
