Fructose-1,6-bisphosphatase (FBPase) and fructokinase (ScrK) have important roles in regenerating glucose-6-phosphate in the pentose phosphate pathway (PPP), and thus increasing l-lysine production. This article focuses on the development of l-lysine high-producing strains by heterologous expression of FBPase gene fbp and ScrK gene scrK in C. glutamicum(More)
The experiments presented here were based on the conclusions of our previous results. In order to avoid introduction of expression plasmid and to balance the NADH/NAD ratio, the NADH biosynthetic enzyme, i.e., NAD-dependent glyceraldehyde-3-phosphate dehydrogenase (GADPH), was replaced by NADP-dependent GADPH, which was used to biosynthesize NADPH rather(More)
Data mining for data stream becomes important in academic areas. Due to large-scale data, people utilize incremental learning approach to handle the data. In this paper, a modified Support Vector Machine (SVM) incremental learning model is proposed. Through experiments of selecting kernel function for the SVM method, we optimize several parameters.
