摘要：

Microorganism compositions are described that comprise combinations of genetic modifications that include a genetic modification to increase oxaloacetate alpha-decarboxylase enzymatic activity. By such genetic modification a 3-hydroxypropionic acid ("3-HP") production pathway is provided or improved. In various embodiments, comprising other genetic modifications, including selected gene disruptions, 3-HP production is greater than in a control microorganism lacking such combinations of genetic modifications
