Microalgae hold tremendous potential for industrial biotechnology. They are an important resource in the production of food and medications, and in many other applications. In comparison to bacteria and fungi, however, they still play only a minor role.
A multi-institution effort has resulted in a paper that details how antigen-coated membrane vesicles derived from the surface of E. coli cells protected mice from a deadly pathogen, and how that system could work against other pathogens, as well.
By using Fourier Transform Infrared Spectroscopy (FTIR), researchers can greatly increase the amount of information that can be extracted from a protein microarray. They show how high-quality spectra can be obtained from spots of protein no larger than the diameter of a human hair.
