Abstract

The present study aimed to isolate endophilic fungi from plant tissues (leaves, stems and roots) of beans, in addition to identifying them at the genus level. The experiment was conducted at IDR-Londrina. Bean samples were collected at the Londrina Research Station and at UENP-Bandeirantes. The leaves, stems and roots were separated, fragments of 5 mm diameter were cut and disinfested. They were later transferred to BDA culture medium. The plates were incubated at room temperature for seven days for growth of the microorganisms present. The presence and absence, colonization rate (TC) for each tissue and gender identification of fungi were evaluated. The experiment was conducted in a completely randomized design, with five replications. Forty-eight endophilic isolates were found, 13 in root, 17 in stem and 18 in leaf. CT ranged from 17-100% (leaf), 17-83% (stem) and 16-100% (root). The genus Alternaria sp. and Cladosporium sp. have greater specificity with the leaf and stem, Penicillium sp. root and stem. The genera Fusarium sp. and Aspergillus sp. are found in all organs, Curvularia sp., Nigrospora sp. and Thichoderma sp. demonstrated leaf specificity, Macrophomina sp. the root, and Colletotrichum sp. to the stem.

Thus, the identified fungi present potential for future studies in their application in the biocontrol of various plant diseases. [ABSTRACT FROM AUTHOR]

Abstract

Spent mushroom substrate (SMS) of P. ostreatus is the residual compost waste generated by the mushroom production industry. The main component of P. ostreatus cultivation is sawdust that high of lignocellulosic material. The presence of cellulose and lignin can be the carbon source of indigenous cellulolytic and lignolytic bacteria. The study was conducted to know the existence of indigenous cellulolytic and lignolytic bacteria and determine their activity or potential character. This research was conducted using the purposive sampling method and analyzed descriptively. The result showed the existance of cellulolytic bacteria (41–51×105 cfu/g) and lignolytic bacteria (60-80 × 105) in SMS. PD04S has a higher cellulolytic index and PYK2L has a higher lignolytic index.

Abstract

Nypa fruticans is a very important mangrove plant especially for coastal communities. It can be used as an alternative medicine. The research was conducted in several steps, there is isolation and identification of endophytic fungi. Isolation of endophytic fungi includes medium preparation, plant sampling, isolation of endophytic fungi from some parts of N. fruticans organs. The identification stage includes purification, characterization, and identification of endophytic fungi. Endophytic isolation obtained 7 isolates are Fusarium, 3 isolates are Aspergillus, 2 isolates are Acremonium, 2 isolates are Colletotrichum, 2 isolates are Scopulariopsis, 2 isolates are Gliocladium, 1 isolate is Trichocladium, and 1 isolate is a Geotrichum.

Abstract

O Parque Nacional dos Campos Gerais foi criado com o propósito de proteger a biodiversidade existente na região dos Campos Gerais do Paraná. A unidade de conservação federal possui mais de 21 mil hectares e abrange parte dos municípios de Ponta Grossa, Castro e Carambeí. Este estudo teve como objetivo levantar dados acerca das espécies do Reino Fungi que ocorrem na região do Parque, a fim de fornecer subsídios para elaboração do plano de manejo da unidade de conservação e contribuir com o conhecimento da biodiversidade da região, ainda pouco elucidada. Além de coleta de dados em campo foi realizada pesquisa em literatura especializada e no banco de dados speciesLink. Os resultados apontam que na região dos Campos Gerais há ocorrência de 55 espécies de fungos. Há pouca literatura disponível e poucos registros em herbários. Esses resultados revelam a necessidade urgente de estudos mais aprofundados e registro de ocorrências. The Campos Gerais National Park was created to protect the existing biodiversity of the Campos Gerais region in the state of Paraná, Brazil. This federal conservation unit has more than 21 thousand hectares spread over the cities of Ponta Grossa, Castro and Carambeí. This study aimed to collect Kingdom Fungi data of species occurring in the Park so as to provide a solid basis for the conservation unit management plan as well as to better understand the park biodiversity. In addition to field data collection, research was carried out using specialized literature and the speciesLink database. Results show that there are 55 fungi species in the Campos Gerais region. Unfortunately, related literature and herbarium records are scarce. These results reveal the urgent need for more in-depth studies and record of occurrences.
