A mycological survey was carried out at Entre Ríos province, Argentina, on sorghum grain, maize, rice, soybean seeds and on freshly harvested and stored wheat. The isolation frequencies and relative densities of species belonging to genera Alternaria, Aspergillus, Fusarium, Penicillium and other fungi were calculated. Alternaria alternata was the major fungal species isolated from sorghum, rice...

Mycotoxins are toxic secondary fungal metabolites. A large variety of mycotoxins have been described, but only a minority of them occur regularly in feed and food items under normal conditions and pose a risk to feed and food safety. The important moulds producing toxins during storage belong to the genera of Penicillium, or Aspergillus. The most important storage toxins are probably ochratoxin...

Fungal contamination is a threat to food safety in West Africa with implications for and feed due their climate, which characterised by high temperatures relative humidity, are environmental favourable fast fungal growth mycotoxin production. This report gives perspective on studies toxigenic fungi (Aspergillus, Fusarium Penicillium) toxins, mainly aflatoxins, fumonisins ochratoxins commonly fo...

Microorganisms are important components of soil. Some soil filamentous fungi such asPenicilium produce many bioactive small molecules, or secondary metabolites, that range frombeneficial bioactive compounds to harmful toxins. In this study, the metabolites of threepenicillium species (P. goditanum, P. moldavicum and P. corylophilum) were extracted byadding ethyl acetate to liquid cultures. The ...

Patulin (PAT) and citrinin (CTN) are the most common mycotoxins produced by Penicillium Aspergillus species often associated with fruits fruit by-products. Hence, simple reliable methods for monitoring these toxins in foodstuffs required regular quality assessment. In this study, we aimed to establish a cost-effective method detection quantification of PAT CTN pome fruits, such as apples pears,...

Recent climatological research predicts a significantly wetter climate in Southern Norway as a result of global warming. Thus, the country has already experienced unusually wet summer seasons in the last three years (2010-2012). The aim of this pilot study was to apply an existing multi-analyte LC-MS/MS method for the semi-quantitative determination of 320 fungal and bacterial metabolites in No...

Lithuanian University of Agriculture, Studentų 11, LT-53361 Kaunas, Akademija, Lithuania. E-mail: [email protected] The article deals with investigation of micromycetes detected on oats grown for food and fodder under climatic conditions of Lithuania. Attention is focused on the oat varieties that are popular in Lithuania and whose grain is used for producing oat flakes and other products...

Two distinct reservoirs of mycotoxins exist in fungal-infected cereal grains--the fungal spores and the spore-free mycelium-substrate matrix. Many fungal spores are of respirable size and the mycelium-substrate matrix can be pulverized to form particles of respirable size during routine handling of grain. In order to determine the contribution of each source to the level of mycotoxin contaminat...

Mycotoxins are toxic secondary metabolites produced under special conditions of moisture and temperature by aerobic, microscopic fungi that can colonize a variety of foods from before harvest up to consumer use. Contamination of beverages, including that of apple juice by patulin and coffee, beer and wine by ochratoxin A has gained worldwide interest in recent years with the revelation of the e...
