摘要

PHB-deficient Sphingomonas strains having improved sphingan yield are provided. Certain of the Sphingomonas strains are diutan-producing strains that exhibit a dramatic improvement in productivity and yield due to a combination of certain genetic modifications that affect PHB and sphingan synthesis. Moreover, the sphingans produced from such strains have superior characteristics including improved filterability, clarity, and improved rheology-modifying characteristics. The sphingans provided are, thus, highly desirable in a variety of commercial and industrial uses, including personal care items, cement applications, and oilfield applications. 展开▼
