1. exoenzymes as a pathogenicity factor for Colletotrichum gloeosporioides associated with coffee plants
RESUMO Fungos fitopatogênicos durante o processo de penetração e colonização são capazes de secretar uma variedade de enzimas, as quais os tornam capazes de infectar o tecido vivo do hospedeiro, atuando na degradação de ceras, cutícula e das paredes celulares. A capacidade de um agente patogênico em produzir ou não enzimas pode determinar o grau d

2. Effect of Non-Starch Polysaccharide (NSP) of Wheat and Barley Supplemented with Exogenous Enzyme Blend on Growth Performance, Gut Microbial, Pancreatic Enzyme Activities, Expression of Glucose Transporter (SGLT1) and Mucin Producer (MUC2) Genes of Broiler Chickens
ABSTRACT The experiment was carried out in a completely randomized design (CRD) with 625 broiler chicks (Ross 308) for 5 repetitions (25 birds per each replicated) on the 5 treatments diet. Treatments included two different types of cereal grains (wheat, and barley) with or without an enzyme supplementation along with a corn-based diet as control group. The

3. Milk-deteriorating exoenzymes from Pseudomonas fluorescens 041 isolated from refrigerated raw milk
The practice of refrigerating raw milk at the farm has provided a selective advantage for psychrotrophic bacteria that produce heat-stable proteases and lipases causing severe quality problems to the dairy industry. In this work, a protease (AprX) and a lipase (LipM) produced by Pseudomonas fluorescens 041, a highly proteolytic and lipolytic strain isolated

4. Caracterização fisiológica e molecular de C. albicans envolvidas em casos de candidíase vaginal e prospecção de óleos essenciais antiCandida. / Physiological characterization and molecular C. albicans involved in cases of vaginal candidiasis and exploration of essential oils anti-Candida.
Espécies de Candida são patógenos oportunistas que podem causar um grande número de infecções, desde mucocutâneas a sistêmicas. No caso de vaginites, sabe-se que mais de 75% das mulheres, já tiveram pelo menos um episódio de candidíase vaginal durante a vida. Os objetivos deste estudo foram (i) caracterizar por parâmetros fenotípicos (produção

5. Sistemática molecular de Trichosporon spp. baseada em genes ribossomais e sua correlação com fatores de virulência e epidemiologia / Molecular systematics of Trichosporon spp. based on ribosomal genes and its correlation with virulence factors and epidemiology
Yeasts of the genus Trichosporon appear as emerging pathogens with high rates of morbidity and mortality in immunocompromised patients and is becoming increasingly widespread. The significant increase of invasive tricosporonose and the controversial identification of this kind imply an epidemiological deficit which in turn complicates the understanding of th

6. Isolamento e caracterização de leveduras fermentadoras de D-xilose, L-arabinose ou D-celobiose e produtoras de celulases e xilanases associadas à madeira em decomposição
Security of a sustainable energy supply providing alternatives to fossil fuels, and market demands are controlling parameters for developing new energy systems, being bioethanol a part of the solution to this problem. The aims of this study were to isolate, identify and characterize yeasts producing exoenzymes and capable of fermenting xylose, arabinose and/

7. Adhesion, exoenzymes activity, susceptibility to Killer toxins and sensibility to antifungal agents of Candida dubliniensis strains isolates from HIV+ individuals / Adesão, produção de exoenzimas, sensibilidade a toxinas Killer e a antifúngicos de cepas de Candida dubliniensis isoladas de pacientes HIV positivos
Candida dubliniensis is a newly described specie which is closely related phylogenetically to Candida albicans. It was first identified as a new specie by Sullivan et al., in Dublin, Ireland, 1995.Numerous researches are attempting to identify more detailed characteristics of C. dubliniensis and similitudes and differences between the two related species.The

8. Endo-beta-mananase de endosperma de Sesbania virgata (Cv.) Pers : purificação, caracterização e importancia na germinação e desenvolvimento da plantula
Many plant seeds have an endosperm, a tissue specialised either as storage or mechanical constraint to embryo growth. In many legume species, endosperms contain galactomannan. This polyssacharide is composed of a main chain of 1,4-β-mannan branched with variable amounts of 1,6-ά-linked galactosyl residues. Three enzymes produced by an aleurone laye

9. Role of Pseudomonas aeruginosa exoenzymes in lung infections of patients with cystic fibrosis.
We investigated the role of Pseudomonas aeruginosa exoenzymes in cystic fibrosis lung infection in the presence and absence of specific serum antibodies. In sputa of 21 cystic fibrosis patients, concentrations of P. aeruginosa proteases and exotoxin A were determined by sensitive radioimmunoassays. In all sputa, detection of exoenzymes was negative (less tha

10. The lux autoinducer regulates the production of exoenzyme virulence determinants in Erwinia carotovora and Pseudomonas aeruginosa.
Erwinia carotovora and Pseudomonas aeruginosa secrete exoenzymes that contribute to the pathogenesis of plant and mammalian infections respectively. E.carotovora mutants defective in synthesis of the pectinase, cellulase and protease exoenzymes were isolated and classified into two groups. Group 2 mutants were found to be defective in the production of a sma

12. Phenotypic conversion of Pseudomonas aeruginosa in cystic fibrosis.
Pseudomonas aeruginosa strains isolated from cystic fibrosis patients were tested for production of exoenzymes, sensitivity to pooled normal human serum, and colony morphology. Strains isolated from patients exhibiting a severe form of the disease were seen to produce a decreased range of exoenzymes, to show an increase in their serum sensitivity, and to be
