Method to produce a polysaccharide gel by increasing the pH of the polysaccharide
The present invention provides for a method of producing a polysaccharide gel comprising: (a) culturing or growing a cyanobacterium or a mixture of cyanobacteria species in a medium under conditions such that the cyanobacterium or the mixture of cyanobacteria species produces a polysaccharide or a mixture of polysaccharides, (b) optionally separating the polysaccharide or the mixture of polysaccharides from the medium and/or the cyanobacterium or the mixture of cyanobacteria species, and (c) increasing the pH of the polysaccharide or the mixture of polysaccharides such that the polysaccharide or the mixture of polysaccharides forms a gel.

Bioprocessing Separations Consortium Three-Year Overview: Technical Advances, Process Economics Influence, and State of the Science
The Bioprocessing Separations Consortium solves separations challenges that are unique to bioprocessing. To do this, the Consortium uses two methods: applying existing technologies to new challenges and developing new technologies that may address these unique challenges better than today’s commercial technologies. In its research and development, the Consortium leverages its three core capabilities: materials development and evaluation, process development, and analysis and computation. In its first three years, from 2016 to 2019, the Consortium addressed four critical challenges in biochemical and thermochemical processing. First, the Consortium targeted the fractionation of lignin to enable valorization of this portion of biomass that offers diverse, complex, and valuable building blocks and products. Second, Consortium researchers developed technologies to enable process intensification, which can reduce equipment needs, energy consumption, and waste generation, thereby cutting bioprocessing capital costs and rendering processes more efficient. Third, the Consortium sought to recover carbon from dilute aqueous streams that are common to bioprocessing; recovering dilute carbon can improve process efficiency and economics. Finally, Consortium researchers designed and developed new materials and catalysts to reduce targeted foulants and poisons in bioprocessing streams that can limit the lifetime of downstream catalysts or fermenting microorganisms. Table 1 lists the technologies that were examined and places them in the context of the Consortium’s capabilities, types of bioprocesses, and critical challenges in bioprocessing separations. Overall, across these projects, we have developed separations technologies for 10 bioprocesses, addressed 9 target compounds in bioprocessing, developed 10 materials, and evaluated 4 processes for cost and sustainability.

Conversion of cellulosic biomass-based sugars to mevalonate for downstream chemical upgrading and market development
In collaboration with Visolis, ABPDU researchers have demonstrated a viable path for conversion of cellulosic feedstocks into renewable precursors for commodity fuels and chemicals. This process was demonstrated with equal success for both glucose and xylose conversion. Following proof of concept in 2L bioreactors, the process was scaled and demonstrated in a 50L bioreactor.

Identification and characterization of an oleaginous microalgal base strain for use in bio-based poly-urethane production
In collaboration with Checkerspot, Inc, researchers at ABPDU have successfully demonstrated production of algal lipids at high rate, titer, and yield in fed-batch fermentation. This technology enables high-intensity fermentation of sugars to algal oil, helping to reduce the cost of algal oils as a highly customizable feedstock for development of new bio-based polyurethanes.
