13. Produção e caracterização da atividade de tirosinase no extrato bruto de Pycnoporus sanguineus CCT-4518 / Production and characterization of tyrosinase activity in Pycnoporus sanguineus CCT-4518 crude extract
Tyrosinase (E.C.1.14.18.1) is an enzyme of industrial interest that catalyses the ohydroxylation of monophenols (monophenolase activity) and the oxidation of o-diphenols to reactive o-quinones (diphenolase activity), both reactions using molecular oxygen. Pycnoporus sanguineus (L. ex Fries) Murril, is a white rot fungi capable of producing tyrosinase and wid

15. Diversidade da comunidade bacteriana endofítica de sementes de soja e o seu potencial biotecnológico / Endophytic bacterial community diversity of soybean seeds and its biotechnological potential
Plant tissues, including seeds, are inhabited by microorganisms called endophytes, whose interaction with the plant can offer advantages to the host. It is known that plants growth promotion is induced by indole acetic acid (IAA) synthesis, phosphate solubilization and nitrogen fixation, among others. The control of phytopathogenic fungi is also related to a

16. Production and characterization of tyrosinase activity in Pycnoporus sanguineus CCT-4518 crude extract / Produção e caracterização da atividade de tirosinase no extrato bruto de Pycnoporus sanguineus CCT-4518
A tirosinase (E.C.1.14.18.1), também conhecida como polifenoloxidase ou catecolase, é uma enzima de interesse industrial que catalisa a o-hidroxilação de monofenóis (atividade monofenolase) e a subseqüente oxidação do o-difenol resultante em o-quinonas reativas (atividade difenolase), usando oxigênio molecular. O Pycnoporus sanguineus (L. ex Fries)

17. Extração, purificação e caracterização de polissacarídeos da biomassa do fungo ascomiceto Botryosphaeria rhodina MAMB-05
The composition of the polysaccharides constituting the biomass of the ascomyceteous fungus, Botryosphaeria rhodina MAMB-05, cultivated on glucose as carbon source was investigated following separation of the exopolysaccharides (EPS). Fungal mycelial biomass was exhaustingly washed with water at room temperature until no residual sugars could be detected (ph

18. Avaliação da presença de fungos e micotoxinas na tecnologia de pós-colheita do milho
Corn is an important cereal crop in Brazil as a major ingredient of animal feed and as raw material included in more than 500 cereal based products. Nevertheless, due to its nutritional quality it becomes an excellent substratum for the toxigenic fungi contamination. In order to evaluate the effect of the time interval between the harvesting and the pre-dryi

19. Quitinases de Beauveria bassiana : produção e polimorfismo genético
Os fungos apresentam uma vantagem com relação a outros entomopatógenos, pois não precisam ser ingeridos para causar a infecção, penetrando o exoesqueleto do inseto por meio da ação de enzimas hidrolíticas como proteases e quitinases. Beauveria bassiana é um entomopatógeno amplamente estudado devido a sua capacidade de infectar e matar várias esp�

20. Uso de genes anti-apoptóticos na construção de plantas de maracujá transgênicas e análise da atividade de diferentes promotores em células vegetais e de insetos
Plants are usually hosts for more than one pathogen. The passion flower, for example, can be infected by a many virus, bactéria and fungi, which limit fruit yield considerably. Due to this, the use of diseases control systems that allow a wide range of disease resistance is needed. Recent work have shown that tobacco or tomato plants containing anti-apoptot

21. FMNL1 : caracterização de um novo gene humano relacionado com a familia das forminas
Formins are proteins that are involved in processes such as morphogenesis, embryonic differentiation, cytokinesis, cell polarity and survival. The formins are multidomain proteins that are conserved from plants to fungi and vertebrates. A search of the ORESTES database, generated from the Human Cancer Genome Project, identified 2 ESTs that were similar to th

22. Reação de progênies de maracujazeiro-azedo ao Colletotrichum gloeosporioides e biocontrole da antracnose com Trichoderma spp.
REACTION OF SOUR PASSIONFRUIT LINEAGES TO Colletotrichum gloeosporioides AND BIOCONTROL OF ANTHRACNOSE BY Trichoderma spp. ABSTRACT Given the importance of the passion fruit crop, where Brazil is the leading world producer, the present work had the objective to evaluate the reaction of lineages of Sour Passionfruit (Passiflora edulis Sims f. flavicarpa Deg.)

23. Aspectos bioquÃmicos e fisiolÃgicos do acÃmulo de polifosfato inorgÃnico por Cunninghamella elegans
Inorganic polyphosphate (PolyP) is a homopolymer of phosphate linked by phosphoanhydride bonds, first indentified a hundred years ago. This molecule is ubiquitous in nature, suggesting the PolyP envolvement in important metabolics process. The fungi are a very important group of organism showing a large application for various biotechnology areas. Despite of

24. Produção e caracterização estrutural do exopolissacarídeos secretado pelo ascomiceto Botryosphaeria SP
The influence of glucose concentration and other carbohydrates (monosaccharides: fructose, galactose, mannose; polyols: mannitol and sorbitol; disaccharides: lactose, sucrose and commercial sucrose; and industrial sugarcane molaless) were compared as sole carbon sources for the production of Botryosphaeran, an exopolysaccharide (EPS) produced by Botryosphaer
