Comparative Evaluation Of Fungal Strains For The Bioprocessing Of Soybean Hulls Using Cheese Whey As Fermentation Medium, Ruchita Bhattarai

Electronic Theses and Dissertations

Globally, soybean is the most widely cultivated oilseed crops, and serve as the primary source of cooking oil, contributing to around 50% of global oilseed production. During the industrial processing of soybean oil, a significant amount of soybean hull (SH) is produced, which makes up about 8% of the grain yield, resulting in approximately 18–20 million tons of hulls, one of the largest by-products in the soybean industry. The hulls have limited commercial value and are primarily used as fiber additives in dairy cattle feed, but a large portion is still discarded as agricultural waste. Similarly, cheese whey (CW), a …

Perceptions Of Plant-Based Meat And Cultured Meat Within The Northern Great Plains Region, Donald Chase Stehly

Dissertations and Theses

Conventional meat consumption derived from livestock farming is one of the leading causes of greenhouse gas emissions and environmental degradation on our planet. Substituting conventional meat products with “meat alternatives” such as plant-based meat or cultured meat would drastically decrease greenhouse gas emissions, reduce land and water pollution, and decrease land and water usage. However, it is necessary to first gauge how people feel about eating plant-based meat and cultured meat before it is possible to discern the magnitude of environmental benefits that occur with a significant dietary change such as this. By administering a questionnaire to over 400 participants …

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

“Fixing” Settler Capitalism: Un/Sustainability In The Former Fort Ord, Clare M. Beer, Sara Salazar Hughes

Urban and Environmental Studies Faculty Works

California's former Fort Ord Army Base is located on the unceded Indigenous territory of the Ohlone Costanoan Esselen Nation. After seven decades as a training ground for foreign wars, the decommissioning of the base triggered an economic, demographic, and cultural crisis for greater Monterey. The solution to this crisis, the Fort Ord Base Reuse Plan, promised sustainable development in the form of local environmental protection, public higher education, and economic growth. We argue that the Fort Ord Base Reuse Plan illustrates a settler sustainability fix, which the state deploys to secure settler capitalist futurity on the Monterey Peninsula at the …

All Peer-Reviewed Publications

In Kenya, aflatoxin contamination in maize remains a persistent issue, with potential negative impacts on both public health and economic growth. Aflatoxins are toxic secondary metabolites produced by certain mold species, primarily Aspergillus flavus. The extent of Aspergillus fungal invasion in maize grains and the resulting increase in aflatoxin levels is heavily influenced by pre-and post-harvest practices. Before harvest, factors such as insect damage and exposure to warm, humid conditions increase the crop's susceptibility to Aspergillus infection and subsequent aflatoxin formation. Post-harvest, additional risks arise when kernels are damaged by pests like rats or when they are stored in unfavorable …
