Abstract: Forests and natural environments are valuable sources of organisms capable of degrading plant cell wall carbohydrates. In the present study, two isolates, Penicillium polonicum and Penicillium chrysogenum, obtained from Brazilian Cerrado soil, along with a previously characterized isolate of...
Abstract: β-Glucosidases catalyze the hydrolysis of β-glycosidic bonds and play key roles in biomass conversion and glycoside processing. We report the identification and characterization of Cr_B1, a GH3 β-glucosidase from Chryseobacterium sp. containing a predicted signal peptide. Cr_B1 hydrolyzed pN...
Resumo: A tecnologia de separação de gases através de membranas se mostra promissora diante da sua processabilidade e aplicação. Esse trabalho tem como objetivo obter e caracterizar membranas poliméricas renováveis (MPR) para separação de dióxido de carbono (CO2). A metodologia consiste em&#...
This classroom-oriented study goes beyond simple visualization by directly comparing laser diffractometry and light microscopy measurements to quantify micron-scale spacings in commercial CDs/DVDs (compact disc/digital versatile disc) and electron-microscopy grids. Diffraction angles from reflection (CD/DVD)&#x...
The objective of this work was to use deep learning and images taken by unmanned aerial vehicles to develop a model to identify the occurrence of macaúba (Acrocomia intumescens) palm trees. The model was trained and tested using data from areas in the southern region of&#...
This study aimed to develop a process for producing ethylene glycol (EG) and glycolic acid (GA) from biomass hydrolysates using robust strains of the yeast Komagataella phaffii. To achieve this, the recombinant strain K. phaffii JA122, capable of producing EG and GA, was constructe...
O objetivo deste trabalho foi validar genes potencialmente envolvidos na resposta da levedura K. phaffii à estes inibidores e obter cepas com maior tolerância a hidrolisados lignocelulósicos. Para isso, genes-alvo foram selecionados a partir de análises de transcriptoma de K. phaffii na ...
O Brasil, sendo o país mais biodiverso do mundo, inclusive no âmbito microbiano, tem grande potencial no desenvolvimento de biorrefinarias para aplicações biotecnológicas com alto teor de inovação tecnológica. Assim, o objetivo deste trabalho foi avaliar 3 linhagens de leveduras, previamente ...
Abiotic stresses negatively impact oil palm (Elaeis guineensis Jacq.) cultivation. Transcription factors (TFs) are essential proteins regulating gene expression in plants. While numerous TF gene families are implicated in plant responses to abiotic stress, their specific roles in oil palm’s droug...
Os carboidratos presentes na biomassa lignocelulósica podem ser usados como fonte de carbono por microrganismos para produzir produtos químicos renováveis. Os processos de pré-tratamento e hidrólise da biomassa levam a liberação de açúcares, mas também acarretam na formação e liberação de co...
