RESUMO O objetivo deste trabalho foi detectar fungos endofíticos associados às sementes de 11 espécies florestais. Dez gêneros foram dessas espécies. Os encontrados com maior frequência nos lotes Aspergillus sp., Penicillium e Fusarium. Encontrou-se também Trichoderma sp. Phomopsis

In spite of the taxonomy of the Aspergillus species of the Nigri Section being regarded as troublesome, a number of methods have been proposed to aid in the classification of this Section. This work aimed to distinguish Aspergillus species of the Nigri Section from foods, grains and caves on the basis in Polyphasic Taxonomy by utilizing morphologic and physiologic characters, and sequencing of ...

Aspergillus sp., Fusarium sp., and Ramularia sp. were endophytic fungi isolated from Rumex gmelini Turcz (RGT), all of these three strains could produce some similar bioactive secondary metabolites of their host. However the ability to produce active components degraded significantly after cultured these fungi alone for a long time, and were difficult to recover. In order to obtain more bioacti...

In this study, twelve fungal lipase producing strains belonging to Aspergillus, Penicillium, Trichoderma and Mucor genera were isolated from palm oil mill effluent composts. The Aspergillus spp. were more frequent (42%) and was present in all the samples assayed. Mucor sp. was the least encountered (8.3%).The lipase producing profile showed that Trichoderma (8.07-8.24 u/mL) and Aspergillus (6.2...

Enzymes associated with release of iron from internalized ferrated siderophore (ferrisiderophore reductase), with damage to the cell at high iron concentration (superoxide dismutase) and siderophore synthesis (alkaline phosphatase), were examined in 3 test fungi viz., Aspergillus sp. ABp4, Aureobasidium pullulans and Rhizopus sp. Extracellular ferrisiderophore reductase activity was present in ...

We present an analysis of the ψψ production from double parton (DP) sacttering and single parton (SP) scattering in the large pT region via color-octet gluon fragmentation. We find that at the Tevatron the DP ψψ production is at the edge of the detectability at present, and at the LHC the DP cross section will dominate over the SP cross section in the lower pT (min) region (i.e., pT (min) < 7Ge...

The biosorption of arsenic (V) on nine chemically modified biomasses (with iron oxide coated) of mycelia fungi: Aspergillus flavus III, IV and V, Aspergillus fumigatus I-II, Paecilomyces sp., Cladosporium sp., Mucor sp-1 and 2 was studied in this work. This study provides evidence that the biomasses of the fungi A. flavus, IV, III and V, Paecilomyces sp., and A. fumigatus I were very efficient ...

The degradation of the cross-linked cationic poly(amino acid)-glutaraldehyde (GA) hydrogels by two kinds of proteolytic enzymes, trypsin and Aspergillus Protease Type XXIII, and by seven species of soil filamentous fungi has been investigated using homo- and copolypeptides of lysine (Lys) and ornithine (Orn). Trypsin degraded the hydrogels prepared from poly(Lys) and copoly(Lys Orn)s but not po...

Tests of the survival of Candida spp., Aspergillus spp., a Fusarium sp., a Mucor sp., and a Paecilomyces sp. on hospital fabrics and plastics indicated that viability was variable, with most fungi surviving at least 1 day but many living for weeks. These findings reinforce the need for appropriate disinfection and conscientious contact control precautions.

orange peel extract solution contains mucilage flavor and three types of glycosides. limonene is one of the terpenoides in some vegetables, fruits and food; that plays as an antioxidant in juice. as it has anti-microorganism effects on some bacteria, we carried out the antifungal effects of limonene versus orange extract. in the present study the effects of orange extract and two types of limon...
