Latest Patents
One of Leinfelder's latest patents is titled "Method for the fermentative production of L-cysteine and derivatives of said amino acid." This invention describes a method for producing L-cysteine and its derivatives, L-cystine and thiazolidine, by fermenting a cysteine-producing microorganism strain in a fermentation medium. The process is characterized by the addition of L-methionine, L-isoleucine, or L-threonine in concentrations ranging from 0.1 to 10 g/L to the fermentation medium during the main culture.
Another significant patent is "Microorganisms for the production of tryptophan and process for the preparation thereof." This patent involves selecting a tryptophan-producing strain of microorganism from Corynebacteria that is resistant to feedback inhibition from both tryptophan and serine. The serine feedback resistance is achieved through a mutation in a serA allele, while the tryptophan feedback resistance is due to a trpE allele mutation.
