Redirect Subcellular Lipid Droplet To Storage Or Excretion

Background: Biodiesel is a renewable and biodegradable fuel that minimizes pollution. The global biofuel market is forecasted to reach $24B with an estimated annual growth rate of 50% in the next 5 years. Therefore, current methods to retrieve biodiesel must be enhanced in order to meet high consumer and commercial demands. Brief Description: UCR researchers have developed a method to optimize biodiesel synthesis in plants by redirecting cytosolic lipid droplets (LDs) to the lumen of the endoplasmic reticulum and then into protein storage vacuoles (PSVs). They successfully identified and modified a specific protein involved in directing lipids to various areas within the cell. Through restructuring and adding novel peptides, researchers were then able to re-route the fate of lipids into vacuoles for accumulation as well as elimination of metabolic feedback inhibition.

Improved Generation of Terpene and Other High-Value Bioproducts from Cyanobacteria and Microalgae

Cyanobacteria and other microalgae can be used as photosynthetic platforms to heterologously generate terpene hydrocarbons and other high-value bioproducts. In addition to being a renewable and biological means of synthesis, cyanobacteria can be grown in high-volume liquid cultures; and terpenes are key ingredients in synthetic chemistry, medical products, cosmetics, and potentially fuels. However, current approaches to generating terpene using microalgae exhibit slow rates of production.   To address these low production levels, researchers at UC Berkeley have developed a method to increase transgenic terpene synthase expression resulting in high rates and yields of terpene hydrocarbon synthesis.   In proof-of-principle experiments, this Berkeley method yielded 20-fold higher amounts of terpene product, which could be easily harvested by siphoning off the top of the culture.

Fully Alloyed Silver and Gold Nanostructures

Background: Biomolecular imaging is important in understanding characteristics of molecules and analyzing quantitative  data for research. Gold has been used for Surface Plasmon Resonance (SPR) which is utilized  for biomolecular imaging. Because of Gold’s high stability structurally and chemically, it is resourceful in this sort of technology.  Compared to Gold, Silver does not have as strong of a stability in non ideal chemical environments, but has high reactivity, supports strong surface plasmon polarization modes, and has higher storage of electrical energy than Gold.Description: UCR researchers have created Silver-Gold  alloy nanospheres through annealing techniques which may be used in SPR that creates optimal and effective results.  By annealing the Silver and Gold metal alloy, it has shown remarkable stability in harsh chemical environments, extremely narrow bandwidths, and shows large extinction pathways. These  specific characteristics enable many plasmonic applications with high performance and long lifetime, especially any involving corrosive species making the Silver-Gold alloy the most favorable choice for SPR.

Novel method to Efficiently Synthesize complex Carbohydrates

Tumor Associated Carbohydrate Antigens (TACAs), have been in great demand due their use as target therapies and industrial relevance. Unfortunately, Pk trisaccharide, the precursor to the globo series of TACAs requires eleven steps to synthesize using current technologies, seven of which are used to develop an orthogonally protected lactose. This is a very costly and painstaking process. Researchers at the University of California, Davis, have developed a two-step method to synthesize orthogonally protected lactose from commercially available lactose, and a three step method to synthesize Pk, providing economic relief and time saving benefits for consumers and manufacturers of TACAs.

Process For Energy-Efficient High Solids Liquefaction Of Biomass

Biofuels significantly reduce the amount of crude oil needed to fuel American cars and trucks, which constitutes two-thirds of the nation’s total demand for oil. Together with efforts to improve fuel economy, biofuels could reduce gasoline consumption to nearly zero. The current cost of biofuels is largely based on a number of key steps in the liquefaction of biomass, which later adds to the cost of distilling the final product. Researchers at the University of California, Davis have developed a novel method to decrease the energy required in processing and liquefaction of solid biomass, thereby substantially decreasing the cost.

It is highly desirable to employ energy-efficient processes for wastewater treatment, and simultaneously recover the energy contained as organic matters in wastewater.  It has been demonstrated that utilizing microbial fuel cell (MFC) technology can generate energy (i.e., electricity).  A microbial fuel cell (MFC) or biological fuel cell is a bioelectrochemical system that drives a current by mimicking bacterial interactions found in nature. These bioelectrochemical devices use electrogenic bacteria to oxidize the organic matter and then transfer the electrons to an electrode and generate electrical energy. UCSC researchers have been pursuing methods to enhance, harness, and utilizes the energy produced directly from the degradation of organic matter in a microbial fuel cell.

Reversible Chemoenzymatic Protein Labeling

Some of nature’s most complex molecules are made by cellular factories that rely on an acyl carrier protein (ACP) to shuttle growing molecules along biological assembly lines. Post-translational protein modification is important for adding functions to proteins that can be exploited for therapeutics, protein engineering, affinity design and enzyme immobilization, among other applications. Commercial techniques for attaching labels to acyl carrier protein (ACP) and other carrier proteins are currently in use.

Improved Condensation Technology

Dehumidifier and condenser applications (where water is condensed onto a chilled surface) are common in power plants, desalination plants, chillers and heat exchangers. In these applications, condensation can be enhanced with an alternating hydrophilic-hydrophobic pattern on the condensation surface. This patterning has been implemented using polymers, self-assembled monolayers and other non-conducting materials. These approaches create chemically heterogeneous surfaces that have limited lifetimes -- due to the thickness and durability of the film.To address this situation, researchers at UC Berkeley have developed a surface with alternating hydrophilic-hydrophobic patterning that promote dual and simultaneous modes of condensation -- filmwise and sustained dropwise condensation -- on a chemically homogenous conducting material (metal substrate) -- which is the material of choice for condenser applications. This innovation is achieved with a practical and scalable technique of surface machining or roughening based on the preferred dimensions of the pattern. The resulting chemically homogenous, conductive substrate is important for maintaining a substrate with high thermal conductivity and doesn't add any thermal resistance that would impede the condensation heat transfer.
