1. Sequencing and de novo assembly of the Asian gypsy moth transcriptome using the Illumina platform
Abstract The Asian gypsy moth (Lymantria dispar) is a serious pest of forest and shade trees in many Asian and some European countries. However, there have been few studies of L. dispar genetic information and comprehensive genetic analyses of this species are needed in order to understand its genetic and metabolic sensitivities, such as the molting mechanis

2. Plant biostimulants: physiological responses induced by protein hydrolyzed-based products and humic substances in plant metabolism
ABSTRACT In recent years, the use of biostimulants in sustainable agriculture has been growing. Biostimulants can be obtained from different organic materials and include humic substances (HS), complex organic materials, beneficial chemical elements, peptides and amino acids, inorganic salts, seaweed extracts, chitin and chitosan derivatives, antitranspirant

3. ProduÃÃo e caracterizaÃÃo do biofilme de quitosana como envoltÃrio protetor em morangos
The shrimp Litopenaeus vannamei is native of the Pacific Ocean and was introduced in the 80s in Brazil. The evolution of the performance of the Brazilian shrimp (1998-2007), increased from 7 thousand to 65 thousand ton./year. This study aimed to produce and characterize chitosan, obtained by desacetilaÃÃo of chitin from shrimp waste, to be used as a protec

4. Análise da expressão gênica no dermatófito Trichophyton rubrum mimetizando a infecção in vitro: pH e diferentes fontes de carbono regulando genes / Analysis of gene expression in the dermatophyte Trichophyton rubrum during the mimetic infection in vitro: pH and carboun sources are regulating genes
Dermatophytes are a group of fungi filamentous that have the ability to invade keratinized substrates, causing dermatophytosis in humans and animals and only penetrate deeper if the host is immunocompromised. Trichophyton rubrum is an anthropophilic and cosmopolitan fungi, the most common agent of superficial mycoses, which uses cell components such as prote

5. Produção de Quitina e Quitosana em cultura submersa de Rhizopus arrhizus nos meios milhocina e sintético para Mucolares
Inquiries had been carried out with submerged fermentation of Rhizopus arrhizus for production of biomass and copolymers chitin and chitosan, using the culture in synthetic medium for Mucoralean and corn steep liquor, as alternative substratum. In this direction, fermentations in Erlenmyers flasks of 250mL had been carried out, contend 50 mL of the media had

6. Synthesis, degradation and functions of insect peritrophic membrane / Síntese, degradação e funções da membrana peritrófica dos insetos
A maior parte dos insetos possui uma estrutura anatômica em forma de filme (membrana peritrófica, MP) composta de quitina e proteínas (peritrofinas), que separa o alimento do epitélio do intestino médio. A MP protege o epitélio de microorganismos e da abrasão, e possui outras funções baseadas no fato de que a MP promove a compartimentalização de e

7. Genomic Analysis and Initial Characterization of the Chitinolytic System of Microbulbifer degradans Strain 2-40
The marine bacterium Microbulbifer degradans strain 2-40 produces at least 10 enzyme systems for degrading insoluble complex polysaccharides (ICP). The draft sequence of the 2-40 genome allowed a genome-wide analysis of the chitinolytic system of strain 2-40. The chitinolytic system includes three secreted chitin depolymerases (ChiA, ChiB, and ChiC), a secre

8. Carbon Export from Arbuscular Mycorrhizal Roots Involves the Translocation of Carbohydrate as well as Lipid
Arbuscular mycorrhizal (AM) fungi take up photosynthetically fixed carbon from plant roots and translocate it to their external mycelium. Previous experiments have shown that fungal lipid synthesized from carbohydrate in the root is one form of exported carbon. In this study, an analysis of the labeling in storage and structural carbohydrates after 13C1 gluc

9. Identification of Enzymes and Quantification of Metabolic Fluxes in the Wild Type and in a Recombinant Aspergillus oryzae Strain
Two α-amylase-producing strains of Aspergillus oryzae, a wild-type strain and a recombinant containing additional copies of the α-amylase gene, were characterized with respect to enzyme activities, localization of enzymes to the mitochondria or cytosol, macromolecular composition, and metabolic fluxes through the central metabolism during glucose-limited c

10. Biochemistry of Sexual Morphogenesis in Schizophyllum commune: Effect of Mutations Affecting the Incompatibility System on Cell-Wall Metabolism
A number of homokaryons of Schizophyllum commune, which carry various mutations affecting the incompatibility system, and a wild-type homokaryon were grown and examined for differences in the net synthesis of the cell-wall polysaccharides S-glucan, R-glucan, and chitin and in the activity of an enzyme hydrolyzing R-glucan (R-glucanase) in mycelial extracts a

11. Widespread N-Acetyl-d-Glucosamine Uptake among Pelagic Marine Bacteria and Its Ecological Implications
Dissolved free and combined N-acetyl-d-glucosamine (NAG) is among the largest pools of amino sugars in the ocean. NAG is a main structural component in chitin and a substantial constituent of bacterial peptidoglycan and lipopolysaccharides. We studied the distribution and kinetics of NAG uptake by the phosphoenolpyruvate:NAG phosphotransferase systems (PTS)

12. Characterization of a Pseudomonas aeruginosa Fatty Acid Biosynthetic Gene Cluster: Purification of Acyl Carrier Protein (ACP) and Malonyl-Coenzyme A:ACP Transacylase (FabD)
A DNA fragment containing the Pseudomonas aeruginosa fabD (encoding malonyl-coenzyme A [CoA]:acyl carrier protein [ACP] transacylase), fabG (encoding β-ketoacyl-ACP reductase), acpP (encoding ACP), and fabF (encoding β-ketoacyl-ACP synthase II) genes was cloned and sequenced. This fab gene cluster is delimited by the plsX (encoding a poorly understood enzy
