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...

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...
