A step forward to empower global microbiome research through local leadership.
Pylro, Victor Satler; Tsai, Siu Mui; Rodrigues, Jorge Luiz Mazza; Andreote, Fernando Dini; Roesch, Luiz Fernando Wurdig; Duarte, Gabriela FroisObtaining the full microbial potential to benefit local communities and citizens, as well as ongoing conservation efforts, is a major challenge for Brazil and other developing countries. We propose policies and priorities for organizing microbiome studies locally and worldwide, aiming for a comprehensive catalogue of microbiomes, as recently urged.
Misguided phylogenetic comparisons using DGGE excised bands may contaminate pub...
Pylro, Victor Satler; Morais, Daniel Kumazawa; Kalks, Karlos Henrique Martins; Roesch, Luiz Fernando Wurdig; Hirsch, Penny R.; Tótola, Marcos RogérioControversy surrounding bacterial phylogenies has become one of the most important challenges for microbial ecology. Comparative analyses with nucleotide databases and phylogenetic reconstruction of the amplified 16S rRNA genes from DGGE (Denaturing Gradient Gel Electrophoresis) excised bands have been used by several researchers for the identification of organisms in complex samples. Here, we individually anal...
Distribution and interaction patterns of bacterial communities in an ornithogen...
Schaefer, Carlos Ernesto G. R.; Rampelotto, Pabulo Henrique; Barboza, Anthony Diego Muller; Pereira, Antônio Batista; Triplett, Eric W.Next-generation, culture-independent sequencing offers an excellent opportunity to examine network interactions among different microbial species. In this study, soil bacterial communities from a penguin rookery site at Seymour Island were analyzed for abundance, structure, diversity, and interaction networks to identify interaction patterns among the various taxa at three soil depths. The analysis revealed the...
Aliphatic hydrocarbon enhances phenanthrene degradation by autochthonous prokar...
Rodrigues, Edmo Montes; Morais, Daniel Kumazawa; Pylro, Victor Satler; Redmile-Gordon, Marc; Oliveira, uraci Alves de; Roesch, Luiz Fernando WurdigThe microbial diversity and functioning around oceanic islands is poorly described, despite its importance for ecosystem homeostasis. Here, we aimed to verify the occurrence of microbe-driven phenanthrene co-oxidation in the seawater surrounding the Trindade Island (Brazil). We also used Next-Generation Sequencing to evaluate the effects of aliphatic and polycyclic aromatic hydrocarbons (PAHs) on these microbia...

Diversidade de bactérias diazotróficas associadas a plantas de milho cultivadas...
Roesch, Luiz Fernando WurdigBactérias diazotróficas podem promover o crescimento do milho por meio da fixação biológica do nitrogênio (FBN) ou pela produção de fitohormônios. Devido a tendência mundial de redução do uso de fertilizantes sintéticos na agricultura, existe um grande interesse em caracterizar a diversidade destes microrganismos para que seu potencial seja melhor explorado. Assim o objetivo deste trabalho foi avaliar a diversi...
