Effect of substratum topography on algal turf colonization and productivity under different nutrient conditions

Kaur, Manjinder (2016-07-28)

Algae can act as a promising source for biofuel production, pollution recovery from natural waters and nutrient recovery from wastewaters. Typical algae cultivation involves algae in the suspended form, and separation ...

Effects of Nutrient Solution Temperature on Lettuce Grown in a Nutrient Film Technique System

Landers, Erin (2017-11-20)

Increases in global population coupled with predicted depletion of natural resources has created a push for more intensive and efficient food production. Greenhouse production has been shown to significantly increase water, ...

Enhancement of Nutrient and Organic Removal from Poultry Litter Using Anaerobic Digestion and Subsequent Algal Growth

Bankston, Elizabeth (2019-07-12)

Research has indicated anaerobically digesting poultry litter can recover energy and reduce pathogen concentrations, which can be used as a nutrient rich media to support algal growth and simultaneously further treat the ...

Enhancing the robustness of Clostridium saccharoperbutylacetonicum N1-4 for butanol production through metabolic engineering and cell immobilization strategies

Jimenez-Bonilla, Pablo (2019-12-06)

n-Butanol (butanol hereafter) has many advantages over ethanol to be used as a biofuel. However, one of the significant drawbacks in bacterial production of butanol is the low productivity and titer due to the low butanol ...

Evaluation of an Algal Turf Scrubber™ (ATS) Approach for the Remediation of Perfluoroalkyl Substances (PFAS)

Lopes Viticoski, Roger (2019-04-17)

Per- and polyfluoroalkyl substances are a large group of synthetic organic chemicals ubiquitous and persistent in the environment due to their fluorinated alkyl chains. Existing methods for remediation of mixtures of PFAS ...

Evaluation of Photogrammetry at Different Scales

Duke, Caleb (2018-04-30)

Accelerated erosion is amplified by anthropogenic effects, which can lead to changes in stream geometry. Stream topography measurements over time quantify stream bank erosion. The goals of this project are to evaluate ...

Lactic Acid Production from Filamentous Algae grown using Aquaponics Wastewater

Burgess, Nicholas (2021-01-07)

Algal Turf Scrubber (ATS) systems are a known method of treating nitrogen and phosphorous rich wastewater by cultivating green filamentous algae biomass. One novel source of this wastewater is from an aquaponics system, ...

Metrology and Characterization of Electrically Conductive Filaments (ECF) for Fused Deposition Modeling (FDM).

Henriquez, Mauricio (2019-12-05)

Current electronics manufacturing is composed of several processes, usually with a high energy, space and knowledge footprint costs to produce a working product. The product is assembled from subcomponents such as the PCB, ...

Process Modeling and Life Cycle Assessment of a Large Pilot-Scale Aquaponics Facility at Auburn University

Kalvakaalva, Rohit (2020-11-13)

Aquaponics has often been hailed as a more sustainable approach to fish and crop production when compared to traditional aquaculture and hydroponics. However, there have been insufficient data to support claim in addition ...

Promoting Nitrification in Poultry Processing Wastewater Treatment Using Microalgae and Biochar

Cherones, Jessa (2022-08-03)

The exponential growth of the global population poses a need for more sustainable food production and waste remediation tactics. Waste-to-resource food production systems such as aquaponics and “poultry-ponics” may be the ...

Removal of pathogenic bacteria in algal turf scrubbers

Rains, John (2016-12-09)

Algal Turf Scrubbers (ATS) are ecologically engineered systems that utilize the growth of filamentous algae on a submerged surface to remediate polluted water using sunlight as the main energy input into the system. Previous ...

Spatial and temporal investigation of taste and odor-producing microorganisms in Lake Saugahatchee
