摘要:
This invention relates to the field of cellular and whole organism engineering. Specifically, this invention relates to a cellular transformation, directed evolution, and screening method for creating novel transgenic organisms having desirable properties. Thus in one aspect, this invention relates to a method of generating a transgenic organism, such as a microbe or a plant, having a plurality of traits that are diffenentially activatable.
摘要:
The invention provides methods for whole cell engineering of new and modified phenotypes by using “on-line” or “real-time” metabolic flux analysis. The invention provides a method for whole cell engineering of new or modified phenotypes by using real-time metabolic flux analysis by making a modified cell by modifying the genetic composition of a cell and culturing the modified cell to generate a plurality of modified cells and measuring at least one metabolic parameter of the cell by monitoring the cell culture of in real time. The invention also provides articles comprising machine-readable medium including machine-executable instructions and systems, e.g., computer systems, to practice the methods of the invention.
