1. Myxomycetes ocorrentes em microhabitates especiais em Ãreas de Floresta AtlÃntica no Nordeste do Brasil: espÃcies florÃcolas / Floricolous myxomycete biota of four Atlantic Forest conservation units in the states of Pernambuco and ParaÃba; Northeast Brazil
Studies on myxomycetes are focused mainly on lignicolous; foliicolous; and corticicolous species; and many types of substrates and environments are still unexplored. Recent research carried out in moist forests suggests high diversity of species in inflorescences of large tropical herbs. This study aimed to increase the knowledge about the Neotropical distri

2. Mixobiota de floresta atlÃntica: espÃcies ocorrentes em Elaeis Guineensis Jacq. (Arecaceae)
A study about the species of myxomycetes that occur on E. Guineensis L. (palm oil) was undertaken with the aim of continuing the survey the this groupâs representatives in Brasil that are associated to palm trees. The incidence, abundance and taxonomic diversity (species/genera) of sporocarps on stipes, leaves, bracts, inflorescences, and fruits (live or de

3. Taxonomia e ecologia dos Myxomycetes ocorrentes na EstaÃÃo EcolÃgica Serra de Itabaiana, Sergipe, Brasil
Os Myxomycetes constituem um grupo de protistas com 870 espÃcies, distribuÃdas em microhabitats diversificados. Eles desempenham importante papel entre os decompositores e na cadeia alimentÃcia da microfauna. As 218 espÃcies previamente descritas para o Brasil distribuem-se nas cinco regiÃes do paÃs, mas a mixobiota de muitos estados ainda nÃo foi des

4. HEMATIN-REQUIRING PLASMODIAL MYXOMYCETE
Daniel, John W. (University of Wisconsin, Madison), Jacqueline Kelley, and Harold P. Rusch. Hematin-requiring plasmodial myxomycete. J. Bacteriol. 84:1104–1110. 1962.—The myxomycete Physarum polycephalum, previously shown to require chick embryo extract for growth on a partially defined, soluble medium, grows as well if hematin or certain hemoproteins ar

5. Methionine Metabolism of the Myxomycete Physarum polycephalum
Daniel, John W. (University of Wisconsin, Madison), and Karlee Babcock. Methionine metabolism of the myxomycete Physarum polycephalum. J. Bacteriol. 92:1028–1035. 1966.—Previous studies have shown that Physarum polycephalum requires exogenous methionine for growth, but not cysteine, folic acid, or vitamin B12. Methionine can also serve as the sole source

7. ORGANIC REQUIREMENTS AND SYNTHETIC MEDIA FOR GROWTH OF THE MYXOMYCETE PHYSARUM POLYCEPHALUM
Daniel, John W. (University of Wisconsin, Madison), Karlee L. Babcock, Alice H. Sievert, and Harold P. Rusch. Organic requirements and synthetic media for growth of the myxomycete Physarum polycephalum. J. Bacteriol. 86:324–331. 1963.—An isolate of Physarum polycephalum was maintained in submersed pure culture in a completely defined medium, giving cell

8. METHOD FOR INDUCING SPORULATION OF PURE CULTURES OF THE MYXOMYCETE PHYSARUM POLYCEPHALUM
Daniel, John W. (University of Wisconsin, Madison) and Harold P. Rusch. Method for inducing sporulation of pure cultures of the myxomycete Physarum polycephalum. J. Bacteriol. 83:234–240. 1962.—Techniques for inducing sporulation of pure cultures of Physarum polycephalum are described. Small plasmodia grown in agitated culture were harvested, allowed to

9. Axenic Culture of Myxamoebae of the Myxomycete Physarum polycephalum
Myxamoebae of the acellular slime mold Physarum polycephalum have been cultured axenically in a soluble medium. The growth medium contains bovine serum albumin, embryo extracts, liver infusion broth, peptone, and glucose. Cell densities ranging from 3 × 106 to 5 × 106 cells/ml have been obtained with this medium. To date, myxamoebae have been serially tran

10. Biosynthesis of Ergothioneine and Hercynine by Fungi and Actinomycetales
Unlike other bacteria, aerobic members of the order Actinomycetales show a close biochemical relationship to the fungi by their capacity to synthesize hercynine and ergothioneine. The myxomycete Physarum polycephalum, possessing the same synthetic ability, also shows this relationship. Contrariwise, the unusual position of yeasts as fungi is indicated by the

11. Characterization of Ribosomes from the Myxomycete Physarum rigidum Grown in Pure Culture
The plasmodial phase of the myxomycete Physarum rigidum, analyzed during the period of rapid growth, attained a ribonucleic acid (RNA) and protein content of 9.8 and 60.0%, respectively, on a dry weight basis. It possessed ribosomes of the 80S class which, especially in the absence of magnesium ions, partially dissociated to 60S and 40S subunit classes. Elec

12. Mass Culture of a Slime Mold, Physarum polycephalum1
The slime mold, Physarum polycephalum, was cultivated in a soluble natural medium in shake flasks and in 30-liter and 50-gal conventional baffled fermentors. Yields of 6 to 10 g (dry weight) per liter were obtained in the large-scale fermentations. Because of the slow growth of the myxomycete, particular attention had to be paid to aseptic technique. The ina
