THE GLOBAL REGULATOR PHOU POSITIVELY CONTROLS GROWTH AND BUTENYL-SPINOSYN BIOSYNTHESIS IN SACCHAROPOLYSPORA POGONA

The Global Regulator PhoU Positively Controls Growth and Butenyl-Spinosyn Biosynthesis in Saccharopolyspora pogona

Butenyl-spinosyn, a highly effective biological insecticide, is produced by Saccharopolyspora pogona.However, its application has been severely hampered by its low yield.Recent studies have shown that PhoU plays a pivotal role in regulating cell growth, secondary metabolite biosynthesis and intracellular phosphate levels.Nevertheless, the function

Theoretical - Experimental Analysis of Cellular and Primary Dendritic Spacings during Unidirectional Solidification of Sn-Pb Alloys

Structural parameters as grain size, dendritic and cellular spacings, segregated products, porosity and other phases are strongly influenced by the thermal behavior of the metal/mold system during solidification, imposing a close correlation between this and the resulting microstructure.Several unidirectional solidification studies with the objecti
