Latest Patents

Fieschko holds a patent for the "Stabilization of a mutant microorganism population." This invention provides a process for stabilizing a population of a mutant microorganism in a bioconversion system whereby the growth of revertant cells is suppressed. The process involves limiting a nutrient essential for cell growth, allowing the cells to selectively grow on a growth carbon source rather than on a non-growth carbon source present in the system. The revertant cells, which have a similar ability as the parent strain of the mutant microorganism to grow on the non-growth carbon source, are effectively suppressed. This innovative approach allows for the metabolism of the non-growth carbon source to an extracellular accumulating quantity of a desired metabolite, such as converting toluene to muconic acid. Fieschko's patent represents a significant advancement in microbial biotechnology.
