Genetic Circuits For Transcriptional Regulation In Synechocystis Sp. Pcc 6803, Cheryl M. Immethun
Genetic Circuits For Transcriptional Regulation In Synechocystis Sp. Pcc 6803, Cheryl M. Immethun
McKelvey School of Engineering Theses & Dissertations
Microbial biosynthesis has produced a variety of complex compounds using processes that are more environmentally-friendly than many conventional methods. The most common hosts are heterotrophs, which require the addition of an organic carbon source; while cyanobacteria possess many traits that make them a more sustainable biotechnology platform. As phototrophs, cyanobacteria can employ sunlight and carbon dioxide to create many value-added compounds. A wealth of tools has been developed to engineer the commonly used heterotrophs for higher yields and titers; yet, few synthetic biology tools have been designed for cyanobacteria. Furthermore, many of the tools created for heterotrophs do not function …
A Multi-Channel 3d-Printed Bioreactor For Evaluation Of Growth And Production In The Microalga Dunaliella Sp, Cristian A. Cox
A Multi-Channel 3d-Printed Bioreactor For Evaluation Of Growth And Production In The Microalga Dunaliella Sp, Cristian A. Cox
Electronic Theses and Dissertations
We explored the capabilities of additive manufacturing using a photo-cured jetted material 3D printer to manufacture a milli-microfluidic device with direct application in microalgae Dunaliella sp growth and intracellular compounds biosynthesis tests. A continuous microbioreactor for microalgae culture was CAD designed and successfully built in 1 hour and 49 minutes using black photopolymer cured by UV and a support material. The microreactor was made up of 2 parts including the bioreactor itself and a microchannel network for culture media fluids and microalgae. Both parts were assembled to form a single unit. Additional optical and auxiliar components were added. An external …
Biomarker Detection At Risk Forecasting Level Using Metal-Enhanced Fluorescence Combined With Surface Acoustic Wave, Jun Liu
USF Tampa Graduate Theses and Dissertations
In this paper, metal-enhanced fluorescence (MEF) technique is used to lower the detection limit of carcinoembryonic antigen (CEA) which is able to be utilized in forecasting the risk of having certain kinds of cancers, especially colon and rectal cancer. By incubating silver nanocubes (Ag NCs) on the surface of the chips, the detection limit goes down to below 1ng/mL of CEA. Also, when combining MEF with surface acoustic wave (SAW) devices, the incubation time between antigen and antibody will decrease significantly with the fluorescence signal keeping similar or higher level.
