Enhancing Algal Biomass And Lipid Production Through Bacterial And Fungal Co-Culture, Erwin David Berthold Jul 2016

Enhancing Algal Biomass And Lipid Production Through Bacterial And Fungal Co-Culture, Erwin David Berthold

FIU Electronic Theses and Dissertations

This thesis investigates the effects of co-culturing microorganisms including 37 yeast, 38 bacteria, nine diazotrophic cyanobacteria, and three fungi on biomass and lipid production in fresh- and saltwater algae. Algal lipid content was measured using Nile Red method and gravimetric techniques. Among the algal strains tested, freshwater Coelastrum sp. 46-4, and saltwater Cricosphaera sp. 146-2-9, showed enhanced biomass yield and lipid content in response to co-culture with bacteria, cyanobacteria, and fungi. While co-culture with yeast caused inhibition of algal productivity, no difference in algal productivity was observed between nitrogen-free diazotrophic cyanobacterial co-culture and nitrogen-replete monoalgal culture. Results indicated that extracellular …


Exploring The Use Of Everglades Agricultural Area Canal Water As Base Medium For The Mass Production Of Algae For Biofuels, Nina N. De La Rosa Nov 2014

Exploring The Use Of Everglades Agricultural Area Canal Water As Base Medium For The Mass Production Of Algae For Biofuels, Nina N. De La Rosa

FIU Electronic Theses and Dissertations

Freshwater use is a major concern in the mass production of algae for biofuels. This project examined the use of canal water obtained from the Everglades Agricultural Area as a base medium for the mass production of algae. This water is not suitable for human consumption, and it is currently used for crop irrigation. A variety of canals were found to be suitable for water collection. Comparison of two methods for algal production showed no significant difference in biomass accumulation. It was discovered that synthetic reticulated foam can be used for algal biomass collection and harvest, and there is potential …
