Prospecting Microbial Strains for Bioremediation and Probiotics Development for Metaorganism Research and Preservation Helena D. M. Villela1, Caren L. S. Vilela1, Juliana M. Assis1, Natascha Varona2, Camille Burke2, David A. Coil2, Jonathan A. Eisen2, Raquel S. Peixoto1,2,3 1LEMM, Laboratory of Molecular Microbial Ecology, Institute of Microbiology Paulo de Góes, Federal University of Rio de Janeiro (UFRJ), 2Genome Center, University of California, Davis, 3IMAM-AquaRio - Rio de Janeiro Aquarium Research Center Pollution affects all biomes. Marine environments have been particularly impacted, especially coral reefs, one of the most sensitive ecosystems on Earth. Bioremediation is the capacity of organisms to degrade contaminants. Here, we describe methodologies to isolate and test microbes presenting bioremediation ability and potential probiotic characteristics for corals.
Preparation and Characterization of Nanoliposomes for the Entrapment of Bioactive Hydrophilic Globular Proteins Anna C. N. T. F. Corrêa1, Patricia R. Pereira1, Vânia M. F. Paschoalin1 1Chemistry Institute, Federal University of Rio de Janeiro This study describes classical hydration using the thin lipid film method for nanoliposome preparation followed by nanoparticle characterization. A 47 kDa-hydrophilic and globular protein, tarin, is successfully encapsulated as a strategy to improve stability, avoid fast clearance, and promote controlled release. The method can be adapted to hydrophobic molecules encapsulation.
CN-GELFrEE - Clear Native Gel-eluted Liquid Fraction Entrapment Electrophoresis Rafael D. Melani*1,2, Henrique S. Seckler*1, Owen S. Skinner1, Luis H. F. Do Vale1,3, Adam D. Catherman1, Pierre C.
