According to the disadvantages and superiority of the middle and small sized enterprises of our country, this paper analyzes the new thought about the marketing orientation from the aspects of marketing product orientation, marketing way orientation, marketing target orientation, marketing strategy orientation and marketing idea orientation. It has great theoretical and practical significance.展开更多

Notably, the rapid and sensitive evaluation of the in vivo concentrations of the desired products greatly facilitates the optimization process of cell factories. For this purpose, many genetic components have been adapted into in vivo biosensors of small molecules, which couple the intracel- lular concentrations of small molecules to easily detectable readouts such as fluorescence, absorbance, and cell growth. Such biosensors allow a high-throughput screen- ing of the small-molecule products, and can be roughly classified as protein-based and RNA-based biosensors. This review summarizes the recent developments in the design and applications of biosensors for small-molecule products.展开更多
