Title: Innovations of Andreas Boehm in L-Cysteine Purification

Introduction

Andreas Boehm is a notable inventor based in Munich, Germany. He has made significant contributions to the field of biochemistry, particularly in the purification of L-cysteine. With a total of 2 patents, his work has implications for various applications in the pharmaceutical and food industries.

Latest Patents

Boehm's latest patents focus on methods for purifying L-cysteine. The first patent describes a method for producing a purified solution containing L-cysteine from a fermentation broth. In this method, the fermentation broth is brought into contact with a basic anion exchanger at a pH value between 6 and 9. The L-cysteine bonds to the anion exchanger, which is then rinsed with a washing solution. The bonded L-cysteine is subsequently removed using an acid and transferred into an eluate. This eluate, with a pH of ≤4, is then treated with an acidic cation exchanger, allowing for further purification.

The second patent outlines a process for separating L-cysteine from an L-cysteine-containing fermenter broth that includes an oxidizing agent. This process involves contacting the broth with an ion exchanger at a pH between 5 and 9, leading to the binding of L-cysteine to the ion exchanger. The bound L-cysteine is then removed using an eluant, facilitating its purification.
