Morphological and molecular characterization of Tulasnella spp. fungi isolated ...
Pereira, Marlon Corrêa; Coelho, Irene da Silva; Valadares, Rafael Borges da Silva; Oliveira, Sabrina Feliciano; Bocayuva, MelissaTulasnella spp. are the main fungal symbionts of Brazilian Epidendrum orchids. The taxonomy of these fungi is largely based on ITS rDNA similarity, but culture dependent techniques are still essential to establish the true biological entity of the mycobiont. The aim of this study was to characterize morphologically and molecularly 16 Tulasnella spp. fungi isolated from three different populations of E. secundum...
Symbiotic propagation of seedlings of Cyrtopodium glutiniferum Raddi (Orchidaceae)
Guimarães, Fernanda Aparecida Rodrigues; Pereira, Marlon Corrêa; Felício, Cristiane da Silva; Torres, Denise Pereira; Oliveira, Sabrina FelicianoIn nature, orchid seeds obtain the nutrients necessary for germination by degrading intracellular fungal structures formed after colonization of the embryo by mycorrhizal fungi. Protocols for asymbiotic germination of orchid seeds typically use media with high concentrations of soluble carbohydrate and minerals. However, when reintroduced into the field, seedlings obtained via asymbiotic germination have lower ...
Enzymatic extract containing lignin peroxidase immobilized on carbon nanotubes:...
Oliveira, Sabrina Feliciano; Luz, José Maria Rodrigues da; Kasuya, Maria Catarina Megumi; Ladeira, Luiz Orlando; Correa Junior, AryThe majority of the textile dyes are harmful to the environment and potentially carcinogenic. Among strategies for their exclusion, the treatment of dye contaminated wastewater with fungal extract, containing lignin peroxidase (LiP), may be useful. Two fungi isolates, Pleurotus ostreatus (PLO9) and Ganoderma lucidum (GRM117), produced the enzymatic extract by fermentation in the lignocellulosic residue, Jatroph...
Diversidade de fungos micorrízicos e endofíticos associados a orquídeas ameaçad...
Oliveira, Sabrina FelicianoO Brasil possui uma grande biodiversidade de orquídeas, principalmente de espécies epífitas. Dentre essa diversidade ressaltam-se as espécies Hadrolaelia jongheana, Hoffmannseggella cinnabarina, Hoffmannseggella caulescens presentes em diferentes formações vegetacionais da Floresta Atlântica. As espécies pertencentes à família Orchidaceae associam-se com fungos micorrízicos para promover a germinação de semente...
