| A total of 297 endophytic fungi were isolated from 1728 leaf and stem fragments collected about twenty and forty days after germination from soybean (Glycine max (L.) Merril) plants grown in the field and a greenhouse. The fungi belonged to eight groups, six dematiaceous genera (Alternaria, Cladosporium, Chaetomium, Curvularia, Drechslera and Scopulariopsis) and the non-dematiaceous genera Acremonium, Aspergillus, Colletotrichum, Fusarium, Paecilomyces and Penicillium along with some Mycelia sterilia.. There were qualitative and quantitative differences in the type and number of isolates obtained from greenhouse and field-grown plants, with more isolates being obtained from the latter. No difference was found in the number of fungi isolated from leaves and... |

| The aim of this study was evaluate, two methods for the detection and identification of sulphate reducing bacteria (SRB): ML medium and PCR with specific primers for SRB groups. SRB were detected through the selective medium only on carbon steel, which showed corrosion. Employing specific PCR primer, SBR were detected from all the metallic components assayed, even those that did not present visible corrosion spots, such stainless steel and copper alloys. Despite the presence or absence of corrosion at the later stages effectively by using the selective medium,, the initial stages of the corrosion could only be detected by the amplification of total DNA with SRB specific primers. The early detection of SRB could be employed for preventing the damages on... |

| O Brasil vem perdendo espaço no mercado internacional devido à piora da qualidade do café. As substâncias tóxicas liberadas pelos fungos além de alterarem a qualidade da bebida, também podem ser prejudiciais à saúde dos consumidores. O objetivo do presente trabalho foi o isolamento de fungos a partir de grãos de café da variedade IAPAR 59, relacionando-os com a qualidade da bebida. Foram realizadas colheitas de grãos da árvore e do solo em diferentes tempos (0, 30, 60, 90 e 120 dias). O isolamento dos fungos foi feito pelo método Pour-plate e para a identificação dos fungos utilizou-se o Microcultivo e a Microscopia Eletrônica de Varredura (MEV). Houve diferença significativa no número absoluto de fungos encontrados nos grãos da árvore (5393), em relação... |
