Industrial-scale production of ethanol in Brazil is not a sterile process and the pure cultures of S. cerevisiae used to inoculate the bioreactors rapidly become contaminated by other yeast and bacteria. During the ethanol production season, the population of organisms in the reactor undergoes complex changes and often the starting S. cerevisae population is outcompeted by wild yeast. The full complexity and dynamics of the microbial population present in a Brazilian industrial fermentation plant is not known because previous studies have relied on low-throughput methods for strain isolation and diversity analysis. Our ultimate goal is to understand population dynamics and the effect of contaminating bacteria and yeast on S. cerevisiae ethanol productivity.
Genome edition and genetic circuits should contribute to increase precision and accelerate metabolic engineering directing gene regulation into plant cells. create cellular networks that integrate input signals for decision making and actuation. Create artificial logic gates and memory devices and implementations of cellular logic and complex gates required the layering of genetic circuits. Utilization of synthetic recombinase-based systems for integrating combinatorial logic and memory in living cells. Engineer oil and protein metabolism pathway of plant-based foods will have significant impacts in the productive sectors and sustainability. Plant metabolism composition is determined by a genetic network mediated by conversion of photosynthesis-inducing conversion of carbon and nitrogen into protein, oil and carbohydrates.

Our program is aim at creating a deeper understanding of the amazon biodiversity with the use of molecular tools. We seed to describe biodiversity through DNA barcoding and in cases where greater resolution is needed we deploy full genomics sequencing. We also evaluate the genetic distribution of selected species using landscape genomics tools and study adaptive mechanisms of plants to the different environments with functional genomics approaches. We are also developing a detailed view of the microbiota of different amazon regions with metagenomics approaches. All experimental studies are supported with by bioinformatics and computational biology tools.

Metabolic studies and production of bioactive compounds of high added value in genetically modified organisms. Metabolic and bioactive compound studies will consist of the chemical characterization of genetically modified plants with emphasis on the identification and/or quantification of secondary metabolites, using a modern approach of dereplication that combines the use of sophisticated spectrometric techniques (Nuclear Magnetic Resonance spectroscopy), and high resolution mass spectrometry) with chemometric methods, coupled with the aid of powerful data bases.

Metabolic engineering of yeasts applied to the production of high added value chemicals
Brazil is known for its vast abundance in biomass. Among those sugar cane and soya are top crops utilized for the production of ethanol e biodiesel respectively. Nevertheless those types of biomass may be also utilized for the production of various chemicals such as bioplastics, biosurfactants and other biopolymers such as hyaluronic acid. Therefore research efforts have turned into developing microorganism strains able to convert raw material into those polymers. The ideal microorganism should convert the raw material and produce the desired polymer in high yield and rate. Yeasts are unicellular microorganisms usually adapted to the harsh industrial environment. They often need genetic manipulation in order to achieve a scalable and economically viable process. Thus research efforts have turned into choosing the appropriate yeast specie for the production of specific biopolymers, genetically engineer them and finally make sure that the fermentation mode matches both industry demand.

Global climate change is increasingly challenge to agricultural production and food security worldwide. Heat, drought and their interaction have had historically great influence on global crop yields. Modification of mitochondrial function is a potential target for enhancing crop yield and tolerance to various stresses. This particular BioSyn program aims the editing of regulatory and coding sequences to modify the function of maize various genes involved with the response and adaptation to abiotic stresses associated with climate change, with a focus on mitochondrial biogenesis and metabolism.
