Agricultural and Biosystems Engineering

Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.

History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract

Ozone was looked at as a possible way to control fungi growth in high moisture (HM) corn. Experiment I stored 22% mc corn at 32C for 9d. Corn was treated for 24h, 5h, or every 3d. Ozone had little impact on dry matter loss (dml) or damage kernel total (dkt) of the HM corn. Experiment II stored 26% mc corn at 15.5C for 30d. Ozone was applied over the initial 24h or every 3, 6, or 12d. Ozone did have a effect on dml, but not on the dkt.;The effectiveness of ozone on fungi in HM corn was studied by enumeration. Moisture contents of 18, 22, and 26% were treated with five ozone concentrations for 1h. Results showed that increasing ozone increased the uninfected kernels. Ozone appeared to have an inhibiting effect on genera in the following order (highest to lowest): Penicillium, Mucor, other genera, Aspergillus, Fusarium, and Rhizopus.
