1. Produção de micotoxinas por Fusarium produtor de galactose oxidase usando diferentes meios de cultivo
O isolado original do fungo produtor de galactose oxidase Dactylium dendroides e outros cinco isolados de Fusarium, também produtores de galactose oxidase, foram cultivados em diferentes meios e condições, com o objetivo de estudar a produção de onze micotoxinas características do gênero Fusarium: moniliformina, ácido fusárico, deoxinivalenol, fusar

3. Biosynthesis and Cellular Distribution of the Two Superoxide Dismutases of Dactylium dendroides
The synthesis and subcellular localization of the two superoxide dismutases of Dactylium dendroides were studied in relation to changes in copper and manganese availability. Cultures grew normally at all medium copper concentrations used (10 nM to 1 mM). In the presence of high (10 μM) copper, manganese was poorly absorbed in comparison to the other metals

4. Regulation of galactose oxidase synthesis and secretion in Dactylium dendroides: effects of pH and culture density.
The effects of pH and growth density on the amount of an extracellular enzyme, galactose oxidase, synthesized by the fungus Dactylium dendroides were studied. Growth at a pH below 6.7 caused a decrease in the ability of the organism to release galactose oxidase. The enzyme retained by these fungal cells was liberated whenever the pH was raised to 7.0. Cycloh

5. Genetic and Morphological Characterization of Cladobotryum Species Causing Cobweb Disease of Mushrooms
Cladobotryum dendroides (= Dactylium dendroides) has hitherto been regarded as the major causal agent of cobweb disease of the cultivated mushroom, Agaricus bisporus. Nucleotide sequence data for the internal transcribed spacer (ITS) regions of four Cladobotryum/Hypomyces species reported to be associated with cobweb disease, however, indicate that the most

6. Interferon: Evidence for Its Glycoprotein Nature
In an attempt to understand the structure of rabbit interferon, the possibility of carbohydrate being part of the molecule was tested. Interferon incubated with neuraminidase from Vibrio cholera is homogeneous in charge as revealed by isoelectric focusing. Treatment of “asialointerferon” with galactose oxidase (EC 1.1.3.9) from Dactylium dendroides and s

7. Effect of Culture Conditions on the Production of d-Galactose Oxidase by Dactylium dendroides1
The effects on enzyme production of inoculum size and age, medium composition, and culture conditions were studied in shake flasks and in a pilot-plant fermentor. Using a medium consisting of glucose, yeast extract, and inorganic salts in deionized water, we found that the addition of Cu++ was essential for the formation of active enzyme. Cultures grown in t

8. Cloning and characterization of cDNA encoding glyoxal oxidase, a H2O2-producing enzyme from the lignin-degrading basidiomycete Phanerochaete chrysosporium.
Glyoxal oxidase is produced by ligninolytic cultures of the white-rot fungus Phanerochaete chrysosporium and is a source of the extracellular H2O2 that is required by ligninolytic peroxidases. We report here the cloning and characterization of glx-1c cDNA, which encodes glyoxal oxidase. The deduced mature protein has 537 amino acids, a molecular size of 57 k

9. fbfB, a Gene Encoding a Putative Galactose Oxidase, Is Involved in Stigmatella aurantiaca Fruiting Body Formation
Stigmatella aurantiaca is a gram-negative bacterium which forms, under conditions of starvation in a multicellular process, characteristic three-dimensional structures: the fruiting bodies. For studying this complex process, mutants impaired in fruiting body formation have been induced by transposon insertion with a Tn5-derived transposon. The gene affected
