Proteinases of various Claviceps purpurea strains
Abstract:
Extra- and intracellular proteinases from various Claviceps purpurea strains grown in submerged culture have been studied. A maximum level of intracellular proteinases was observed on the 6th day of culture growth, whereas extracellular activity continued to increase throughout the culture growth. Proteinases were purified and characterized. The ergotamine strain secreted one aspartic and two serine proteinases, whereas from the disrupted mycelium only the aspartic proteinase could be isolated. The ergocornine strain secreted the aspartic proteinase in two forms and the ergocristine strain produced an aspartic and a serine proteinase.

Strain Energy
Consider a rod that is fixed at one end and subjected to an axial force at the free end. This axial force induces stress within the rod, leading to its elongation. As the axial force increases, so does the elongation of the rod, illustrating a direct relationship between the force applied and the resulting...
