Alternative Sweeteners For Cultivating Water Kefir Grains, Morgan Barnes
Alternative Sweeteners For Cultivating Water Kefir Grains, Morgan Barnes
Honors Theses
Water kefir is traditionally fermented using dark brown sugar due to a fast growth rate, however the use of other sweeteners, such as honey, is relatively unexplored. This paper describes the investigation of using alternative mediums made with honey, agave nectar, Truvia/stevia, and monk fruit sweetener, each supplemented with dark brown sugar on the biomass growth of water kefir grains (WKGs). Growth in these alternative mediums was compared to WKG growth in the standard medium prepared using only dark brown sugar. Two trials were conducted, each with three replicates for each experimental medium as well as three replicates of dark …
A Comparative Analysis Of The Fermentation Capabilities Of Various Bifidobacterium Strains, Ella Oney
A Comparative Analysis Of The Fermentation Capabilities Of Various Bifidobacterium Strains, Ella Oney
Honors Theses
Bifidobacterium is a genus of anaerobic bacteria that are commonly found to inhabit the gastrointestinal tract of many members of the animal kingdom. These microorganisms are adapted to obtain their carbon from the breakdown of complex carbohydrates. Marmosets, a mammal whose gut microbiome is inhabited by high levels of Bifidobacteria, consume gum Arabic as a major part of their diet. The purpose of this experiment is to determine whether Bifidobacterium strains isolated from the guts of marmosets are able to degrade and ferment this complex carbohydrate or one of its main constituents, arabinose. This was accomplished by inoculating isolates of …
