Molecular Detection Of Aspergillus Flavus In Georgia Peanut, Variety Tifguard., Carolle Zolome

Symposium of Student Scholars

Peanuts provide a good source of protein, minerals, and vitamins to consumers. The US peanut industry suffers great losses of nearly $26 million annually due to contamination by Aspergillus species. In spite of strict control measures against Aspergillus species, the industry is still facing economic loss due to contamination by this mold. Poor storage of peanuts in commercial outlets can lead to infection by the mold, releasing aflatoxin which is carcinogenic. A number of DNA based techniques are currently available for identification of the fungal population. This research aims at identifying if peanut, the variety Tifguard which is highly recommended …

Aspergillus flavus is known to contaminate peanuts and produce aflatoxin which are carcinogenic metabolites. According to the USDA, more than $1 billion is spent on infection and prevention. Currently there is no single method known to eradicate Aspergillus spp. in peanuts and the industry continue to face the aflatoxin problem. There has been an increased interest in use of plant based antifungal products which are environmentally friendly and …

Evaluating Volatile Organic Compounds For Contact-Independent Antagonism Of Pseudogymnoascus Destructans

Symposium of Student Scholars

White-nose syndrome (WNS), a disease caused by the fungus Pseudogymnoascus destructans, is responsible for the extensive mortality of bats in the United States. In an effort to develop tools to reduce bat mortality attributed to WNS, an in vitro experiment was conducted to quantify the inhibitory effects of select volatile organic compounds (VOCs) as well as explore potential synergistic activities. The experiment involved exposing mycelial plugs of P. destructans to various concentrations of B23 as well as B23 and decanal together at equimolar ratios. Measurements of the plugs were taken over the course of the 13 day experiment allowing …
