Facilitating Growth of Photosynthetic Microbes with CO2 Nanobubbles
Photosynthetic microbes are promising contributors to the bioeconomy. With light and CO2, they can create biomass, biofuels, green chemicals, food ingredients and more. Typically, CO2 is delivered by sparging; however, CO2 macrobubbles quickly rise to the surface and are lost to the atmosphere. This gas transfer inefficiency not only increases operational...

Extraction and Thermal Protection of Phycocyanin
Phycocyanin is a bright-blue pigment-protein complex, found in phycobilisomes, and makes up a large fraction (up to 20-25%) of the dry weight of cyanobacterial cells. The global demand for phycocyanin is increasing due to a growing public preference for natural compositions in food coloring, cosmetics and other industry applications. However, given...

Soil Inoculants for Restoration of Degraded Arid Soils
Large swaths of arid land are under severe, increasing anthropogenic stress, with degrading or already degraded soils. Regeneration of biocrusts, photosynthetic communities which act as the natural biological cover of arid soils and increase nutrients into them, has promise for dryland restoration and sustainability. However, unaided recovery of biocrust...

Photosystem I-Hydrogenase Chimeras and Processes for Biohydrogen Production
With increased demand for energy, particularly from inexpensive, renewable, and environmentally friendly sources, Hydrogen (H2) is an attractive target product, with over 60 million tons produced globally. Unfortunately, around 95% of hydrogen is produced from steam reformation of fossil fuels, contributing to rising atmospheric CO2. Reengineering fundamental...

Microbial Electro-Photosynthesis for improving energy conversion efficiency in photosynthetic microorganisms
While photosynthetic microorganisms offer a promising route to generate sustainable transportation fuels and products using solar energy, boosting their photosynthetic efficiency above normal levels (<5%) will help ensure its economic viability. A major source of inefficiency is that photosynthetically active radiation (PAR, 400-700 nm) constitutes...

Methods of Increasing Biomass Productivity in Algae Cultures
Two challenges facing the world today include the ongoing pollution of the environment with carbon dioxide and the increasing consumption of the world’s natural energy resources of fossil fuels. An elegant solution to these challenges would be to cultivate microorganisms such as algae that take and utilize carbon dioxide for their growth while...

Photosynthetic Production of Acyl-CoAs as Precursors for Ethyl Ester Synthesis & Other Chemicals
Petrochemical sources for industrial feedstocks and fuels is finite, thus a shift toward alternative and renewable sources continues to be a high priority in the US and around the world. Photosynthetic microorganisms, such as cyanobacteria, are one such potential source. These microorganisms have been extensively studied and different pathways genetically...

Integrated Filamentous Algal and Cyanobacterial Process for Manufacturing Biofuels and Co-Products via Fractionation of Flue Gas, Wastewater, and Solid Agricultural Waste
Background The growing environmental concern surrounding fossil fuel consumption has driven tremendous research and development efforts into alternative energy sources. Microalgae are currently considered one of the most promising feedstocks for biofuel production. Compared with more common feedstock sources such as corn and sugarcane, microalgae have...
