The aim of this study was the study of the abiotic environment of the carnivorous pitcher plant Heliamphora nutans (Sarraceniaceae), including the microclimate and the geochemistry of the soil of the growing sites on Roraima Tepui and discuss their relevance within the recent model of carnivorous plant ecology. The soil was peaty and low in nutrients. The microclimate on the site was very balanced, with moderately cool temperatures, a constant high humidity and very low wind speed. Heliamphora was not exposed to any recognizable climatic stress. Previous macroclimatic measurements reflected the growth conditions of Heliamphora only incorrectly, since humidity decreased drastically with height. The apparent conflict with the common model of carnivorous... |

With the advent of recombinant DNA technology, recombinant protein expression has become an important tool in the study of the structure, function and identification of new proteins, especially those with therapeutic functions. Escherichia coli has been the predominant prokaryote used in genetic engineering studies due to the abundance of information about its metabolism. Despite significant advances in molecular biology and immunology of infections, there are as yet no prophylactic drugs capable of preventing visceral leishmaniasis. It is therefore important to identify specific antigens in order to develop vaccines and diagnostic kits against this disease. The objective of this study was to evaluate the influence of culture medium on the production of... |

Cordyceps is a fastidious pathogenic fungus infecting insects, and recent years have witnessed rapid progress in its medical properties. In this study, a wild isolate, C. cicadae MP12, was characterized through in vitro cultivation and its nuclear small-subunit (SSU) ribosomal DNA (rDNA) data. In vitro culture of C. cicadae MP12 was established by growing its fruiting bodies in a solid matrix. C. cicadae MP12 was inoculated into Cryptotympana atrata cicada pupae for in vivo culture, where the fungi developed its fruiting body as well. The contents of adenosine and cordycepin in dried fruiting bodies after culture were 1421.45µg/g and 1398.12 µg/g, respectively. Therefore, the established cultures from this study could be used for the production of various... |

The objective of this work was to study the effect of caffeine and tannins on Pleurotus sp. cultivation and to evaluate the feasibility of using coffee husks as substrate for mushroom cultivation. Eight strains of P. ostreatus and two strains of P. sajor-caju were screened on a medium prepared from agar extract of coffee husk. Based on best mycelial growth and biomass production, the strain P. ostreatus LPB 09 was selected for detailed studies. With the increase of caffeine concentration, the mycelial growth and the biomass production decreased, and no growth was observed when concentration of caffeine was 2500 mg/L. Furthermore, Pleurotus did not degrade the caffeine, but absorbed it. Tannin under 100 mg/L in the medium stimulated the growth of mycelia,... |

Actualmente se estudia la capacidad funcional a nivel molecular de los hongos basidiomicetos como modificadores de la respuesta biológica, dada la efectividad de los productos examinados de activar al sistema inmunológico, sin embargo, el origen geográfico de estos recursos, principalmente son asiáticos y europeos. Ganoderma es reconocido por su eficiente actividad en el tratamiento de varias enfermedades, principalmente las anticancerígenas y antitumorales, crece de manera silvestre en el área central de México, una de las más importantes, debido a la convergencia de las regiones Neártica y Neotropical, lo cual da como resultado un amplia diversidad de recursos genéticos. En la presente investigación se aislaron 66 cepas del género Ganoderma producto de... |

Local ecological knowledge (LEK) can shed light on ecosystem change, especially in under-researched areas such as South Africa’s Wild Coast. However, for ecosystem planning purposes, it is necessary to assess the accuracy and validity of LEK, and determine where such knowledge is situated in a community, and how evenly it is spread. Furthermore, it is relevant to ask: does LEK add value to science, and how do science and local knowledge complement one another? We assessed change in woodland and forest cover in the Nqabara Administrative Area on South Africa’s Wild Coast between 1974 and 2001. The inhabitants of Nqabara are “traditional” Xhosa-speaking people who are highly dependent on natural resources for their... |

The medicinal species fafia (Hebanthe eriantha), is a product of extractivism in the region of the Paraiba Valley, São Paulo state, Brazil, with endangered genetic variability. This study did an agronomical characterization and an analysis of active compounds of five accessions. This research is a partnership of UNESP-Botucatu Medicinal Plants Laboratory, Paraiba Valley Center (APTA) and CPQBA-UNICAMP Agrotechnological Division. A field experiment using completely random blocks with five accessions and seven replications was used. The stem and leaf wet/dry weights, root wet/dry weight, length of the longest stem, foliar area, foam index and pfaffic acid content samples were evaluated. Accession I1800 had root dry weight, stem and leaf dry weight, and... |
