Effects of Carbon Dioxide Levels on Growth and Pigments of Freshwater Algae
Title
Effects of Carbon Dioxide Levels on Growth and Pigments of Freshwater Algae.
Creator
Bermudez, Jeanne, Louda, J. W., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Chemistry and Biochemistry
Abstract/Description
This project was designed to investigate the effects of carbon dioxide (CO2) levels on the growth and pigment ratios (chemotaxonomy) of freshwater algal species typical to the south Florida surface waters. Green algae, diatoms, and cyanobacteria were cultured under 400 or 800 ppm CO3 in air for several weeks. Growth monitoring used a cell counter, hemocytometer, and chlorophyll fluorescence. Pigments were analyzed using HPLC-PDA. Experiments with certified CO2 concentrations (400, 600, 800,...

Green algae, diatoms, and cyanobacteria were cultured under 400 or 800 ppm CO3 in air for several weeks. Growth monitoring used a cell counter, hemocytometer, and chlorophyll fluorescence. Pigments were analyzed using HPLC-PDA. Experiments with certified CO2 concentrations (400, 600, 800, 1200 ppm) were conducted with helium degassed ultrapure water and each of three culture media. Theoretical and experimental pH values with water matched exactly. However, each culture media proved to exhibit significant buffer capacity. Cell growth monitoring was problematic except for the cyanobacterium Microcystis aeruginosa. That species responded to increased CO2 (800 ppm) with increased growth rates as predicted. The other species gave erratic results mainly due to difficulties in obtaining valid consistent cell counts.

Tropical crustose coralline algal community and individual growth responses to light and elevated pCO2
Title
Tropical crustose coralline algal community and individual growth responses to light and elevated pCO2.
Creator
Dutra, Elizabeth A., Koch, Marguerite, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
Crustose coralline algae (CCA) are important reef stabilizers and their susceptibility to anthropogenic climate change and ocean acidification (OA) is of concern. Ocean acidification effects on benthic algal communities were determined by the response of CCA, fleshy macroalgae and microalgae to the interaction of pCO2 and light. I examined if elevated pCO2 and light influences CCA dominance by assessing their growth, recruitment and calcification. Elevated pCO2 under natural reef diurnal CO2...
Show moreCrustose coralline algae (CCA) are important reef stabilizers and their susceptibility to anthropogenic climate change and ocean acidification (OA) is of concern. Ocean acidification effects on benthic algal communities were determined by the response of CCA, fleshy macroalgae and microalgae to the interaction of pCO2 and light. I examined if elevated pCO2 and light influences CCA dominance by assessing their growth, recruitment and calcification. Elevated pCO2 under natural reef diurnal CO2 cycles did not significantly affect CCA percent cover, calcification rates or survival of adult CCA lobes. No significant community pCO2 effects were observed, rather light controlled dominance. The percent cover of microalgae increased in highlight, while CCA increased in the shade. My results indicate that algal response to irradiance is a more significant driver of reef benthic algal change than pCO2 levels predicted for 2100; however, this conclusion should be corroborated in longer-term and in field experiments.

Abstract/Description
Human exposure to arsenic from natural as well as anthropogenic sources can lead to a detrimental impact to the nervous system, cardiovascular system and can also cause cancer. Historical agricultural runoff has led to an accumulation of arsenic in groundwater and soils around Lake Okeechobee and many golf courses in Florida.

Show moreHuman exposure to arsenic from natural as well as anthropogenic sources can lead to a detrimental impact to the nervous system, cardiovascular system and can also cause cancer. Historical agricultural runoff has led to an accumulation of arsenic in groundwater and soils around Lake Okeechobee and many golf courses in Florida. This research involved studying the removal of aqueous arsenic via adsorption using activated carbon derived from algae. Carbon derived from Sargassum removed 41.47% of arsenic after a contact time of 2 hours. Adsorbents created from blue-green algae showed essentially no arsenic removal under the same conditions. Various chemical additives were tested to improve arsenic adsorption as well. Modification of the adsorbent surface with magnesium chloride demonstrated an arsenic removal efficiency of 98.6% when added to commercial activated carbon. However, when magnesium chloride was used to modify the surface of Sargassum-derived carbon adsorbents, the arsenic removal efficiency after 2 hours was 26.7%. It is recommended to investigate other surface modification agents that can potentially improve adsorption of arsenic.
