AbstractLipase is a kind of industrial enzyme preparation with various catalytic abilities and is widely used in food, energy, medicine and other fields. To increase lipase and enzyme cocktail activity through solid-state fermentation, the novel strain Penicillium sp. Y-21 was obtained through ethyl methanesulfonate (EMS) mutation from the novel strain Y, which was isolated from soils. Solid-state fermentation by strain Y-21 using agricultural byproducts was carried out in tray bioreactors.

3.2. Internal Force and Displacement AnalysisThe spacing between the double rows of sheet piles in the cofferdam is 10 m, which is much larger than the width of a single sheet pile. When the sand filling reaches the active limit equilibrium state, the angle between the damaged surface and the sheet pile is considered to be 45° − φ/2.
