1. Evaluation of endoglucanase and β-glucosidase production by bacteria and yeasts isolated from a eucalyptus plantation in the cerrado of Minas Gerais
Resumo O atual cenário ambiental e econômico global tem uma relação intrínseca com o aumento do consumo de combustíveis fósseis causados pelo desenvolvimento de tecnologias e pelo crescimento da população mundial. Assim, é necessário procurar fontes renováveis de biocombustíveis na tentativa de mitigar os efeitos dos combustíveis fósseis no me

2. Microbiota fóssil em sílex da Formação Assistência (Subgrupo Irati, Permiano, Bacia do Paraná) no Estado de São Paulo / Fossil microbiota in chert from Assistência Formation (Irati Subgroup, Permian, Paraná Basin) in São Paulo State
The study of petrographic thin sections of early diageneteic chert from diverse levels and localities of the Assistência Formation in the state of São Paulo, Brazil, revealed for the first time an exceptionally well-preserved assemblage of delicate fossil microorganisms in this important stratigraphic and paleontological Early Permian marker unit of the Pa

3. Spirochete and protist symbionts of a termite (Mastotermes electrodominicus) in Miocene amber
Extraordinary preservation in amber of the Miocene termite Mastotermes electrodominicus has led to the discovery of fossil symbiotic microbes. Spirochete bacteria and wood-digesting protists were identified in the intestinal tissue of the insect. Fossil wood (xylem: developing vessel-element cells, fibers, pit connections), protists (most likely xylophagic a

4. Origin of the Eumetazoa: Testing ecological predictions of molecular clocks against the Proterozoic fossil record
Molecular clocks have the potential to shed light on the timing of early metazoan divergences, but differing algorithms and calibration points yield conspicuously discordant results. We argue here that competing molecular clock hypotheses should be testable in the fossil record, on the principle that fundamentally new grades of animal organization will have
