With integrated DoE and MVDA software tools, you can implement QbD strategies early on to define your design space and gain process understanding at moderate resource investment.

Upstream and Downstream Processes

Upstream processing comprises tasks in the initial stages of the fermentation process in biotechnology. This includes all steps related to the development of microorganisms, nutrient preparation , cell culture , cell separation and harvesting. Upstream processing involves nutrient preparation. Like humans, cells in a culture also need the right nutrition to function and to produce the intended value product. The nutrients consist predominantly of different components, such as carbohydrates glucose , nitrogen amino acids , fats lipids and trace amounts of salt.

As a business owner or operations manager responsible for production, understanding the supply chain is essential to the success of your business. Any obstacle or impediment to the smooth flow of production can mean thousands of dollars lost and problems with the clients who depend on the delivery of your goods. The manufacturing production process can be pictured like a river. It's not unusual to hear people involved in production make frequent reference to "upstream" and "downstream" parts of the process. Upstream refers to the material inputs needed for production, while downstream is the opposite end, where products get produced and distributed.

Tannin acyl hydrolase also referred as tannase is an enzyme with important applications in several science and technology fields. Due to its hydrolytic and synthetic properties, tannase could be used to reduce the negative effects of tannins in beverages, food, feed, and tannery effluents, for the production of gallic acid from tannin-rich materials, the elucidation of tannin structure, and the synthesis of gallic acid esters in nonaqueous media. However, industrial applications of tannase are still very limited due to its high production cost. Thus, there is a growing interest in the production, recovery, and purification of this enzyme. Recently, there have been published a number of papers on the improvement of upstream and downstream processing of the enzyme. These papers dealt with the search for new tannase producing microorganisms, the application of novel fermentation systems, optimization of culture conditions, the production of the enzyme by recombinant microorganism, and the design of efficient protocols for tannase recovery and purification. The present work reviews the state of the art of basic and biotechnological aspects of tannin acyl hydrolase, focusing on the recent advances in the upstream and downstream processing of the enzyme.
