Plastic polymers are petroleum-derived synthetic materials that have multiple uses in everyday life, but their excessive production has led to the accumulation of approximately 1,000 million tons residues, causing negative ecological impacts. This study analyzed biological degradation liquid medium polyurethane, polystyrene, and polyethylene samples by filamentous fungi isolated from Antarctica...

We have quantified vegetable growers' exposure to fungal bioaerosol components including (1→3)-β-d-glucan (β-glucan), total fungal spores, and culturable fungal units. Furthermore, we have evaluated factors that might affect vegetable growers' exposure to fungal bioaerosols and airborne dust. Investigated environments included greenhouses producing cucumbers and tomatoes, open fields producing ...

The study was carried out to enumerate fungal contamination, and toxigenicity of Aspergillus flavus strains on cacao beans during drying storage. As many as 3500 g storage were purchased from smallholder farmers the plantation areas at Karo Regency, Northern Sumatera. percentage contaminated by fungi conducted using direct plating. Fungal populations soil determined dilution followed pour plate...

Maize grain samples (n=15) collected during the autumn of 2002 were analyzed for the presence of moulds and mycotoxins fumonisin B1 (FB1), fumonisin B2 (FB2), zearalenone (ZEA), and ochratoxin A (OTA). Mycological analysis showed that all samples were contaminated with Fusarium spp. and Penicillium spp., while Aspergillus spp. were found in 5 samples. F. proliferatum and F. verticilloides, the ...

Marine fungi have been shown to be tremendous sources for new and biologically active secondary metabolites which are reflected by the increasing number of published literature dealing with compounds from this group of fungi. As a result to these efforts, more than a hundred secondary metabolites from marine fungi have been described. The mycobiota of the coastal water were collected from five ...

Thesafety characteristics of feed used in fish and crustacean aquaculture systems are an essential tool to assure the productivity of those animal exploitations. Safety of feed may be affected by different hazards, including biological and chemical groups. The aim of this preliminary study was to evaluate fungi contamination and the presence of aflatoxins in 87 samples of feed for sea bass, col...

BACKGROUND Otomycosis is a superficial fungal infection often involves the pinna and external auditory canal. It is a pathologic condition, with Candida and Aspergillus, the most common fungal species. It is common worldwide but more prevalent in tropical and subtropical countries. OBJECTIVES The aim of this study was to determine the etiologic agents and local epidemiologic pattern of otomyc...

In the dryland Pacific Northwest wheat cropping systems, no-till is becoming more prevalent as a way to reduce soil erosion and fuel inputs. Tillage can have a profound effect on microbial communities and soilborne fungal pathogens, such as Rhizoctonia. We compared the fungal communities in long-term no-till (NT) plots adjacent to conventionally tilled (CT) plots, over three years at two locati...
