Biofilms play an important role in degradation, transformation and assimilation of anthropogenic pollutants in aquatic ecosystems. In this study, we assembled a tubular bioreactor containing a biofilm substrate and aeration device, which was introduced into mesocosms to explore the effects of bioreactor on physicochemical and microbial characterist...
As xilanases são enzimas que hidrolisam ligações Beta-14 presentes na hemicelulose que compõe a parede celular vegetal. Essas enzimas são produzidas por bactérias, fungos e plantas. Por apresentarem diversas aplicações, como na fabricação de pães, na indústria farmacêutica, na fabricação de celulose e na geração de biocombustíveis, o objetivo desse...
Sewage sludge digestate is a valuable organic waste which can be used as fertilizer in soil bioremediation. Sewage sludge digestate is not only a good source of nutrients but is also rich in bacteria carrying alkB genes, which are involved in aliphatic hydrocarbons metabolism. Increase of alkB genes ratio in polluted soils has been observed to impr...
High titer, rate, yield (TRY), and scalability are challenging metrics to achieve due to trade-offs between carbon use for growth and production. To achieve these metrics, we take the minimal cut set (MCS) approach that predicts metabolic reactions for elimination to couple metabolite production strongly with growth. We compute MCS solution-sets fo...

Systems metabolic engineering faces the formidable task of rewiring microbial metabolism to cost-effectively generate high-value molecules from a variety of inexpensive feedstocks for many different applications. Because these cellular systems are still too complex to model accurately, vast collections of engineered organism variants must be system...
A shortage of blood during the pandemic outbreak of COVID-19 is a typical example in which the maintenance of a safe and adequate blood supply becomes difficult and highly demanding. So far, human RBCs have been produced in vitro using diverse sources: hematopoietic stem cells (SCs), embryonic SCs and induced pluripotent SCs. The existing, even saf...
Les cellules souches mésenchymateuses (CSM) sont largement utilisées en thérapie cellulaire et en ingénierie tissulaire. Leur intérêt est lié à leur activité paracrine ainsi qu'à leur capacité de différenciation. Les CSM sont des cellules rares qui ont besoin d’être amplifiées à grande échelle pour une utilisation clinique. Comme ce sont des cellul...
Abstract Every aspect of yeast physiology is subject to robust temporal regulation, this becomes apparent under nutrient-limiting conditions 1-6 and results in biological oscillations whose function and mechanism is poorly resolved 7 . These yeast metabolic oscillations share features with circadian rhythms and typically interact with, but are inde...
Cost competitive conversion of biomass-derived sugars into biofuel will require high yields, high volumetric productivities and high titers. Suitable production parameters are hard to achieve in cell-based systems because of the need to maintain life processes. As a result, next-generation biofuel production in engineered microbes has yet to match ...

Research in the field of heart muscle tissue engineering is focused on the fabrication of heart muscle tissue which can be utilized to repair, replace and/or augment functionality of damaged and/or diseased tissue. In the simplest embodiment, bioengineering heart muscle tissue constructs involves culture of cardiomyocytes within natural or syntheti...
