1. Dry fruit as source of fungal contaminants or functional compounds?
Abstract This study evaluated the role of dry fruits as a source of fungal contaminants or functional compounds. Dry apple, apricot, candied fruits, prune, and white and black raisin were evaluated regarding patulin and ergosterol content, centesimal composition, pH, acidity, pectin, and phenolic profile. The ergosterol was detected in 38% of the samples and

4. Indoor Air Quality in the Hospital: The Influence of Heating, Ventilating and Conditioning Systems
Abstract Clean, fresh air is the most important requirement for good indoor air quality (IAQ) in all buildings, but it is especially important with regard to the environments within hospitals and other healthcare facilities. The literature indicates that buildings with heating, ventilating and air conditioning (HVAC) systems may have an increased risk of sic

5. In vitro culture and diversity of endophytic fungi in Bambusa oldhamii
RESUMO Bambusa oldhamii Munro é uma espécie de bambu lenhoso de crescimento rápido e com forte apelo comercial. No Brasil, o uso dessa espécie é limitado, devido, principalmente, à baixa disponibilidade de mudas para plantios comerciais. A micropropagação é uma técnica de produção de mudas em larga escala, porém, protocolos de estabelecimento de

6. Production of biocomposites from the reuse of coconut powder colonized by Shiitake mushroom
RESUMO A procura por compósito biodegradável vem crescendo mundialmente nos últimos anos, principalmente com o intuito de reduzir a contaminação ambiental por materiais estruturais produzidos a partir de derivados de petróleo. O objetivo deste estudo foi avaliar o crescimento de isolados do cogumelo comestível “Shiitake” (Lentinula edodes) em subs

7. Can Aspergillus fumigatus conidia cause false-positive results in the galactomannan enzyme immunoassay test?
Abstract INTRODUCTION: Several factors can cause false-positive results in the galactomannan (GM) test; however, others remain unknown. Presently, the impact of airborne contamination by Aspergillus conidia during enzyme-linked immunosorbent assay (ELISA) remains uninvestigated. METHODS: We studied 12 A. fumigatus isolates. Fungal conidia were serially d

8. BIODEGRADACION FUNGICA DE POLIURETANO RÍGIDO
Polyurethane (PU) is one of the most widely used polymer materials. This generates a serious environmental problem because of its poor biodegradability since most of the native microorganisms cannot use it as a source of nutrients. Several techniques involving mechanical and chemical processes have been used for its recovery and reuse; however, the problem o

9. Potential of popcorn germplasm as a source of resistance to ear rot
ABSTRACT Because of its multi-purpose nature, popcorn has sparked the interest of the World Trade Organization as regards fungal contamination by mycotoxins. However, no investigations have been conducted on popcorn for resistance of genotypes to ear rot. The aim of this study was to evaluate the potential of popcorn genotypes as to resistance to ear rot and

10. Deoxynivalenol in wheat and wheat products from a harvest affected by fusarium head blight
Abstract Fusarium head blight is an important disease occurring in wheat, caused mainly by the fungus Fusarium graminearum. In addition to direct damage to crops, reduced quality and yield losses, the infected grains can accumulate mycotoxins (toxic metabolites originating from prior fungal growth), especially deoxynivalenol (DON). Wheat crops harvested in 2

11. The Antifungal Properties of Peppermint and Thyme Essential Oils Misted in Broiler Houses
ABSTRACT This study aimed at evaluating if essential oils misted in broiler houses reduce environmental fungi counts. The investigation was conducted in three experimental rooms, where broiler chickens were reared between 1 to 42 d of age. Every three days, the rooms were fogged with pure water (control) or with aqueous solutions of peppermint or thyme oils.

12. Fusarium and Aspergillus mycotoxins contaminating wheat silage for dairy cattle feeding in Uruguay
Abstract Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage
