13. Production of plant cell wall degrading enzymes by monoculture and co-culture of Aspergillus niger and Aspergillus terreus under SSF of banana peels
Filamentous fungi are considered to be the most important group of microorganisms for the production of plant cell wall degrading enzymes (CWDE), in solid state fermentations. In this study, two fungal strains Aspergillus niger MS23 and Aspergillus terreus MS105 were screened for plant CWDE such as amylase, pectinase, xylanase and cellulases (β-glucosidase,

14. Screening of thermotolerant and thermophilic fungi aiming β-xylosidase and arabinanase production
Plant cell wall is mainly composed by cellulose, hemicellulose and lignin. The heterogeneous structure and composition of the hemicellulose are key impediments to its depolymerization and subsequent use in fermentation processes. Thus, this study aimed to perform a screening of thermophilic and thermotolerant filamentous fungi collected from different region

15. Identification of the soybean HyPRP family and specific gene response to Asian soybean rust disease
Soybean [Glycine max (L.) Merril], one of the most important crop species in the world, is very susceptible to abiotic and biotic stress. Soybean plants have developed a variety of molecular mechanisms that help them survive stressful conditions. Hybrid proline-rich proteins (HyPRPs) constitute a family of cell-wall proteins with a variable N-terminal domain

16. Proteome characterization of sugarcane primary cell wall / Caracterização do proteoma da parede celular primária de cana-de-açúcar
Este estudo fornece informação para auxiliar o uso da parede celular vegetal, a partir do bagaço de cana, para a produção de etanol celulósico. Com isso, as proteínas da parede celular de folhas, colmos e células em suspensão foram identificadas. Para isso, foram utilizados diferentes protocolos. Utilizando folhas e colmos de cana-de-açúcar de doi

17. Estudos iniciais de caracterização funcional de peroxidases e laccases potencialmente envolvidas no processo de lignificação em cana-de-açúcar / Initial studies on the functional characterization of peroxidases and laccases potentially involved in the lignification process in sugarcane
Lignin is a complex heteropolymer deposited in the secondarily thickened walls of specialized plant cells to provide strength and rigidity for plants to stand upright and hydrophobicity to conducting cells for long-distance water transport. Although lignin is essential for plant growth and development, this phenolic polymer is the major plant cell wall compo

18. Cell wall, lignin and fatty acid-related transcriptome in soybean: achieving gene expression patterns for bioenergy legume
Increasing efforts to preserve environmental resources have included the development of more efficient technologies to produce energy from renewable sources such as plant biomass, notably through biofuels and cellulosic residues. The relevance of the soybean industry is due mostly to oil and protein production which, although interdependent, results from coo

19. An overview of lignin metabolism and its effect on biomass recalcitrance
Lignin, after cellulose, is the second most abundant biopolymer on Earth, accounting for 30% of the organic carbon in the biosphere. It is considered an important evolutionary adaptation of plants during their transition from the aquatic environment to land, since it bestowed the early tracheophytes with physical support to stand upright and enabled long-dis

20. Hidrólise enzimática de carboidratos de soja [Glycine max (L.) Merrill] e efeitos em tofu tipo silken
A adição de Viscozyme L na suspensão de soja pode resultar em um tofu com características diferentes do tradicional. Devido à ação da enzima, material da parede celular (polissacarídeos) poderá ser parcialmente hidrolisado liberando mono e oligossacarídeos, os quais serão transferidos para o tofu, provavelmente modificando sua composição e textu

21. Caracterização da mobilização dos polissacarídeos da parede celular em palhada de cana de açúcar submetida às condições de campo. / Characterization of cell wall polysaccharides mobilization in sugarcane straw cell wall in the field.
O etanol celulósico a partir da palhada de cana pode elevar a produção do bioetanol, porém esta é normalmente decomposta no campo. A degradação da parede celular no campo não foi elucidada e compreender este processo auxiliará na produção de etanol celulósico. O objetivo deste trabalho foi caracterizar a degradação da palhada de cana de açúca

22. Flooding tolerance and cell wall alterations in maize mesocotyl during hypoxia.
This research aimed to characterize the tolerance to flooding and alterations in pectic and hemicellulose fractions from mesocotyl of maize tolerant to flooding when submitted to hypoxia. In order to characterize tolerance seeds from maize cultivars Saracura BRS-4154 and BR 107 tolerant and sensitive to low oxygen levels, respectively, were set to germinate.

23. Caracterização bioquímica e molecular da ß-Galactosidade durante a maturação de frutos de coffea arabica
ß-galactosidases are a class of glycosyl-hydrolases that act on the plant cell primary walls, hydrolyzing ß-D-galactose at the nonreducing ends of ß-D-galactosides present in several biological molecules. Initially a characterization of the monosaccharides present in the primary wall of the pericarp and endosperm of Coffea arabica fruits at different ripe

24. Purification and characterization of cytosolic and cell wall β-galactosidases from Vigna unguiculata stems
Three β-galactosidase isoforms, β-gal I and β-gal II (cytosolic) and β-gal III (cell wall-associated), were isolated from stems of Vigna unguiculata (L.) Walp. cv. Pitiúba seedlings. Purification consisted of aμMonia sulfate fractionation followed by chromatography in DEAE-Sephadex and Lactosyl-Sepharose columns. The two cytosolic isoforms showed the s
