Synthetic Bacterial Microcompartment Shell Proteins Derived by Circular Permutation and/or Genetic Fusion

INTRODUCTION Bacterial microcompartments (BMCs) are organelles used by various bacteria to encapsulate metabolic pathways into a proteinaceous shell. BMCs serve as scaffolds to organize encapsulated enzymes and as physical boundaries to reduce diffusive loss of volatile or toxic intermediates and restrict crosstalk with cytosolic biosynthetic pathways....

Method For Removing PFAS in Liquids

VALUE PROPOSITION Per- and polyfluoroalkyl substances (PFAS) are a widely used but toxic and carcinogenic group of man-made chemicals. They are extremely resistant to degradation and will persist in the environment and in the human body. PFAS are highly water soluble, thus contaminated drinking water is the primary source of exposure. The most common...

Engineered Shell Proteins to Enable Electron Transfer Across the Shell of a Bacterial Microcompartment

INTRODUCTION Bacterial microcompartments (BMCs) are organelles used by various bacteria to encapsulate metabolic pathways into a proteinaceous shell. Because of their attributes (self-assembling modules, optimization of the reactions in their lumen.) they have potential as catalytic bioreactors that can be customized to support new metabolic functions....

Repulpable Omniphobic Paper Packaging Solution

Executive SummaryTraditional grease- and water-resistant paper packaging solutions have significant environmental concerns. Water-resistant products using low-density polyethylene (LDPE) liners are not repulpable, increasing municipal waste footprint. Oil-resistance is often achieved using toxic per and polyfluoroalkyl substances, which have been associated...

RF Detection of Analytes

Executive SummaryDue to public health concerns since the 1920’s, the U.S. dairy industry is federally required to be monitored and treated for bacterial contamination. Most municipalities mandate pasteurization to reduce the number of viable pathogens likely to cause disease. Pre- and post-pasteurized milk is often tested for contamination via...

Biodegradable Slow Release Pesticide Plugs and Mechanized Injection System

Executive SummaryProfitability in domestic and global fruit markets requires meeting high food quality standards, often through the judicious use of pesticides. Currently, these pesticides are applied using airblast sprayers up to 10 times per growing season. Airblast sprayers deliver only 29 to 56% of the sprayed solution to the tree canopy. A new...
