Exploring Single Cell Microbial Protein As A Sustainable Fishmeal Alternative In Yellowtail Kingfish (Seriola Lalandi) Diets: Impacts On Health And Gut Microbiome, Luke Pilmer, Lindsey Woolley, Alan Lymbery, Chinh Dam, Abigail Elizur, Md Javed Foysal, Gavin Partridge

Fisheries Research Articles

Background

With the global expansion of aquaculture and the increasing demand for fish meal, identifying appropriate and sustainable alternative protein sources for aquafeeds has become essential. Single-cell protein (SCP), derived from methanotrophic bacteria, presents a promising alternative by converting methane into protein, potentially addressing both the need for alternative protein sources and reducing industrial greenhouse gas emissions. This study aimed to evaluate the effects of different levels of SCP inclusion (0%, 25%, 50%, and 75% fish meal replacement) on the health, gene expression, and gut microbiome of yellowtail kingfish (YTK, Seriola lalandi) following a 35-day growth trial.

Research outputs 2022 to 2026

Currently no data exists on S-methyl-L-cysteine sulfoxide (SMCSO) levels in Australian-sourced vegetables and limited data exists for glucosinolates. The effect of various cooking methods on the retention of SMCSO and glucosinolates in Australian-sourced vegetables is also limited. This study measured SMCSO and ten glucosinolates in a selection of Australian-sourced Brassica vegetables, both raw and after steaming. We additionally measured SMCSO and glucosinolate levels in broccoli after microwaving, stir-frying and boiling. SMCSO contributed greater dry weight (0.6–1.9 %) than total glucosinolates combined (0.3–1.2 %) in these raw cruciferous vegetables. SMCSO levels from highest to lowest were: Brussels sprouts > broccoli > red cabbage …

The transmission and infection of enteric viruses can be influenced by co-existing bacteria within the environment and host. However, the viral binding ligands on bacteria and the underlying interaction mechanisms remain unclear. This study characterized the association of norovirus surrogate Tulane virus (TuV) and murine norovirus (MNV) as well as the human enteric virus Aichi virus (AiV) with six bacteria strains (Pantoea agglomerans, Pantoea ananatis, Bacillus cereus, Enterobacter cloacae, Exiguobacterium sibiricum, Pseudomonas spp.). At room temperature, the viruses bound to all bacteria in strain-dependent rates and remained bound for at least 2 h. The virus association with two gram-positive bacteria …

Enhancing In Vitro Digestibility And Volatile Profile Of Sorghum Proteins Using Supercritical Carbon Dioxide Drying, Nafisa Sadaf, Arda Tuhanioglu, Safoura Ahmadzadeh, Ali Ubeyitogullari

Food Science Faculty Publications and Presentations

The goal of this research was to use supercritical carbon dioxide (SC-CO2) drying as a novel approach to generate sorghum protein concentrates with enhanced functional characteristics. Sorghum protein concentrates were extracted from white whole-grain sorghum flour and dried in two ways: freeze-drying and SC-CO2 drying. The dried proteins were characterized for their volatile compound content, in vitro digestibility, and amino acid composition. A more porous structure was observed for the SC-CO2-dried sorghum proteins compared with their freeze-dried counterparts. In the SC-CO2-dried samples, the levels of alcohols, esters, and organic acids were significantly lower than those in the freeze-dried ones, whereas …

How Can University-Community Partnerships Strengthen Food Literacy To Improve Food Access And Food System Resilience In Rhode Island?, Jocelyn Furtado

Student Publications

Nearly two out of every five households in Rhode Island experience difficulties accessing adequate and nutritious food, falling into the category of food insecure. While it is not the responsibility of a sole organization to reverse this complex systemic issue, collaborative efforts are a step toward combating food insecurity and systems resilience through improving food literacy. When accomplished within a community, adequate food literacy can combat food insecurity. To the same effect, food insecurity may cause a lack of food literacy.

To hone in on the relationship of food literacy as it relates to food insecurity and food systems resilience, …

Decreasing Food Waste In Home Kitchens By Increasing Food Literacy, Thao Rich

Student Publications

In a world that produces enough food for all of its occupants, a staggering amount of it bypasses empty stomachs and goes into landfills every day. There it sits in a plastic bag, which delays decomposition and increases the harmful greenhouse gas emissions. There are numerous reasons for the inequitable distribution of food ranging from politics to logistics, but the fact is that each person can make a dent in reducing their carbon footprint by simply reducing the amount of food they place in the trash each week. Food waste reduction is a small goal that requires no additional spending, …

Modeling Wild Rice Bed Health: A Dual Metric Approach For Bed Strength And Invasive Impact, Seth Sisneros-Martinez

Journal of Earth and Life Science

Wild rice (mannoomin; Zizania palustris) is an aquatic grain that grows in slow-moving rivers and shallow bays throughout northern Minnesota. In Headquarters Bay on Leech Lake, wild rice has served as a cultural staple for Indigenous communities for centuries. However, its population has declined in recent years due to multiple environmental issues. One potential contributor is Eurasian watermilfoil (Myriophyllum spicatum; EWM), an invasive species that forms dense mats capable of outcompeting native aquatic vegetation, including wild rice. EWM was first recorded on the southern shoreline of Leech Lake in 2005 and has since become widespread. This study …
