Definition of Yield: In lean manufacturing, the "area of improvement" is the part of the system under observation. In other words, it's the part of the factory where defects are produced the most. The goal is to find and fix these defects before they cause any more harm. The concept is a tool used to measure how close you are to meeting.

Biocatalysis refers to the use of living systems or their parts to speed up chemical reactions. In biocatalytic processes, natural catalysts, such as enzymes, perform chemical transformations on organic compounds. Both enzymes that have been more or less isolated and enzymes still residing inside living cells are employed for this task. Modern biotechnology, specifically directed evolution, has made the production of modified or non-natural enzymes possible. This has enabled the development of e.
