The Gene Expression Patterns Of Phanerochaete Chrysosporium And Trametes Versicolor On Diverse Lignocellulosic Feedstocks, Noor Osama Alabbasi Jan 2021

The Gene Expression Patterns Of Phanerochaete Chrysosporium And Trametes Versicolor On Diverse Lignocellulosic Feedstocks, Noor Osama Alabbasi

Masters Theses

Plant biomass is considered to be an important future starting material for fuels and chemicals, thereby decreasing our reliance on fossil fuels. While direct combustion continues to be a source of fuel, the generation of liquid fuels from plant biomass for transportation has proven to be challenging. Among the limiting factors for conversion of this material to biofuels is the recalcitrant nature of lignocellulose, the primary component of non-starch plant biomass. A strategy to overcome this dilemma is to directly or indirectly use the enzymes from white-rot fungi, which have evolved a unique ability to deconstruct lignocellulose. However, the biochemical …


Transcriptome Analysis Of Neuro-2a Cells Treated With Asiatic And Madecassic Acid, Fatimah M. Alqam Jan 2020

Transcriptome Analysis Of Neuro-2a Cells Treated With Asiatic And Madecassic Acid, Fatimah M. Alqam

Masters Theses

Traditional herbal medicine is ingrained as a source of therapeutic compounds to medicate various diseases. The family Araliaceae (Ginseng family) is rich in traditional medicine species, such as Centella asiatica (CA). For many centuries, CA has been used by the indigenous Indian and Chinese in Ayurvedic and traditional medicine, respectively, to improve intelligence, learning, memory, and cognitive performance. Previous studies on cell culture and animal models supported the beneficial effects of CA on the nervous system. However, the exact composition of CA extract and its molecular mechanism that leads to neuroprotection is still unclear. We examined the effect of asiatic …


The Transcriptome Response Of The White-Rot Fungus Trametes Versicolor To Wild-Type And Lignin-Modified Hybrid Poplar, Anbarah Alzabaidi Jan 2020

The Transcriptome Response Of The White-Rot Fungus Trametes Versicolor To Wild-Type And Lignin-Modified Hybrid Poplar, Anbarah Alzabaidi

Masters Theses

Plant biomass is a renewable and sustainable feedstock for biofuel production that can reduce societal dependence on fossil fuels. However, the production of liquid biofuels from the non-starch (i.e. lignocellulosic) material through fermentation technology is limited due to the complexity of the cell wall structure. This necessitates the use of chemical, thermal, and/or mechanical pretreatment technologies, which adds significant capital, operational, and environmental costs. Biological pretreatment strategies have the potential to mitigate these expenses by harnessing the innate ability of specialized bacteria and fungi to deconstruct lignocellulose. White-rot fungi (e.g. Trametes versicolor) have been shown to be …


Comparative Transcriptome Analysis Of Wild Tomato Species During Fruit Development, Altynay Zhanayeva Mar 2017

Comparative Transcriptome Analysis Of Wild Tomato Species During Fruit Development, Altynay Zhanayeva

Masters Theses

Fleshy fruits in different species can display large variation in color. A link between fruit color and seed dispersal success is suggested by previous studies showing that high intensity of fruit color increases the visitation rate in seed-dispersing birds. Wild tomato species (Solanum spp.) are excellent model organisms for research on genetic basis of differential fruit color development during the ripening process. Despite polymorphism in fruit color, all tomato species have yellow flowers due to accumulation of carotenoid pigments, which suggests that the carotenoid pathway is intact. Thus, regulatory changes controlling enzymes activity during fruit maturation are likely …
