Title: Innovations of Allison J Pieja in Microbial Biosynthesis
Introduction
Allison J Pieja is an accomplished inventor based in Menlo Park, CA (US). He has made significant contributions to the field of microbial biosynthesis, particularly in the production of polyhydroxyalkanoates (PHA) from organic waste materials. With a total of 2 patents, his work focuses on sustainable methods for bioplastic production.
Latest Patents
One of his latest patents is titled "Use of selection pressures to enable microbial biosynthesis of polyhydroxyalkanoates from anaerobic degradation products." This innovative method involves operating a sequencing bioreactor in alternating phases of nutrient deprivation and carbon feedstock deprivation. The goal is to select for robust PHA-producing microbes, preferably in a non-sterile manner with mixed cultures of methanotrophs. The method also incorporates periodic biomass-wasting for PHA harvesting, which incentivizes PHA accumulation while penalizing rapid degradation.
Another notable patent is "Bacterial poly(hydroxy alkanoate) polymer and natural fiber composites." This invention describes a biocomposite produced from natural fiber fabrics embedded in a matrix of biosynthetic PHA polymers. The PHA is synthesized using aerobic microbial biosynthesis with feedstock derived from anaerobic degradation products. This biocomposite has potential applications in various industries, including bioplastics.
