Title: David A. Glassner: Innovator in Succinic Acid Production

Introduction

David A. Glassner is a notable inventor based in Okemos, MI (US), recognized for his contributions to the field of biotechnology. He holds a total of 4 patents, focusing primarily on processes related to the production and purification of succinic acid. His innovative approaches have the potential to significantly impact the efficiency and cost-effectiveness of succinic acid production.

Latest Patents

Among his latest patents, Glassner has developed a fermentation and purification process for succinic acid. This process involves growing a succinate-producing microorganism on a low-cost carbohydrate substrate. It includes simultaneously neutralizing the fermentation broth and precipitating the succinate as calcium succinate by adding a calcium ion source. The calcium succinate is then isolated, slurried in water, and treated with sulfuric acid to yield calcium sulfate and succinic acid. The final product undergoes treatment with both a strongly acidic ion exchanger and a weakly basic ion exchanger to remove impurities, resulting in a highly purified succinic acid product.

Another significant patent by Glassner outlines a process for the production and purification of succinic acid. This method involves growing a succinate salt-producing microorganism on an inexpensive substrate containing carbohydrates, nutrients, sodium ions, and tryptophan under a CO₂ partial pressure. The fermentation broth is electrodialyzed to recover and concentrate the succinate salt, which is then subjected to water-splitting electrodialysis to produce base and succinic acid. The resulting product is treated with ion exchangers to ensure high purity.
