The occurrence of moulds and aflatoxins in groundnut kernels are of great concern to food processors and consumers because of their ability to cause spoilage resulting to economic losses and public health problem such as aflatoxicosis. This study was aimed at determining the presence of Aspergillus species and aflatoxin levels in fresh harvested and stored groundnuts kernels from non-mechanized...

PHB degradation capabilities of seven species of Aspergillus namely Aspergillus niger, Aspergillus flavus, Aspergillus ochraceus, Aspergillus nidulans, Aspergillus terreus, Aspergillus fumigatus and Aspergillus parasiticus on the polymer produced by Rhodospseudomonas palustris KU003 were assayed . Among all the fungi investigated, the ability of A.niger to utilize the biopolymer was the highest...

The present investigation aimed to study and compare the efficiency of non-viable fungal isolates to remove divalent lead (Pb(II)) from aqueous streams. The selected fungal isolates showed identity with Aspergillus caespitosus, Aureobasidium sp. RBSS-303 and Aspergillus flavus HF5 as confirmed using gene sequencing of ITS regions of the ribosomal DNA (rDNA). The obtained equilibrium data for Pb...

Twelve species belonging to six fungal genera were found to be associated with wheat (Triticum aestivum L.) grain samples collected from three main regions in Saudi Arabia. The most common genera (average frequency) were Aspergillus (14.3%), Fusarium (29.1%), Penicillium (9.3%), and Alternaria (8.2%). Nineteen isolates of Aspergillus flavus were screened for their ability to produce aflatoxins ...

aflatoxins are secondary toxic metabolites produced by some aspergillus spp. particularly, aspergillus flavus and a. parasiticus that contaminate food and feed. the objective of this study was to evaluate the contamination of feedstuffs with aspergillus spp. and detect genes involved in the aflatoxin biosynthesis pathway of a. flavus and a. parasiticus isolates. a total of 110 cow feed samples ...

The mycological profile of the retail wheat flour selling in different markets at Jeddah (Kingdom of Saudi Arabia) was studied. The most common genera were Aspergillus (isolated from 70% of the tested samples), Penicillium (30%), Eurotium (14%), and in a lesser extent Fusarium (20%) and Alternaria (18%). Twenty-nine strains of Aspergillus flavus were screened for their ability to produce aflato...

Background: Aspergillus flavus is a toxic contaminant in foods, which can induce mutagenic, teratogenic, and carcinogenic effects. In last decades, synthetic fungicides have been used for inhibition of fungal growth in plants. The public attention was also attracted to contamination of food chain by these chemicals. Therefore, in the current study, we decided to use Zataria multiflora (ZM) esse...

Marshall, K. C. (Cornell University, Ithaca, N. Y.) and M. Alexander. Nitrification by Aspergillus flavus. J. Bacteriol. 83:572-578. 1962.-Aspergillus flavus has been shown to produce bound hydroxylamine, nitrite, and nitrate when grown in peptone, amino acid, or buffered ammonium media. Free hydroxylamine was not detected in these cultures, but it was found in an unbuffered ammonium medium in ...

A comparative molecular study of Aperigiullus protease using sequence gene representative 25 different Aspergillus species (Aspergillus fumigatus, oryzae, flavus, novofumigatus, viridinutans, pseudotamarii, clavatus, sojae, fischeri, caelatus, campestris, costaricaensis, candidus, neoniger, mulundensis, ibericus, niger, piperis, eucalypticola, vadensis, steynii, and lentulus) have been describe...

Corn produced in the southeastern United States has higher levels of aflatoxin than corn produced in the Corn Belt states of the Midwest (Zuber et al.,1976). Because corn acreage has increased recently in Louisiana, there is a growing concern among corn producers regarding levels of aflatoxin in their grain. Although the most effective control of A. flavus and aflatoxin contamination is through...
