Abstract: Aspects of the invention provide a switching power supply that exhibits an improved conversion efficiency. In aspects of the invention, a load condition detecting circuit sets a threshold voltage for determining the magnitude of the load on the DC-DC converter based on the maximum value of the output voltage of the power factor correction converter in a suspended period of the power factor correction converter. An operation permission signal is delivered when a feedback voltage that indicates the magnitude of the load of the DC-DC converter exceeds the threshold voltage. When the feedback voltage exceeds a threshold voltage that is set at a value higher than the threshold voltage, the operation permission signal is delivered.

Abstract: The present invention provides a method of increasing extracellular secretion of secretory proteins by co-expressing the secretory proteins with a mature cutinase. Cutinase can improve the permeability of E. coli cell membrane without destroying the membrane, and thus facilitate cross-membrane transfer of the secretory proteins co-expressed in E. coli. Increased extracellular secretion of target proteins can shorten cell culture time, reduce the formation of inclusion bodies and increase production of target proteins.
