摘要:
The present invention provides Bacillus subtilis HA KCCM-10775P having a high productivity of protease, fibrinolytic enzyme and mucilage, a method preparing fermented soybeans (e.g., Cheonggukjang) using the same strain, in which bean fragments, soybeans and black soybeans are fermented, and fermented soybeans (e.g., Cheonggukjang) produced according to the said method. The Bacillus subtilis HA KCCM-10775P isolated from traditional fermented soybeans (e.g., Cheonggukjang) and identified is the superior strain having a high productivity of protease, fibrinolytic enzyme and mucilage. When preparing fermented soybeans (e.g., Cheonggukjang) using the strain of the present invention, it has good sensory properties by removing a peculiar smell thereof, as well as a high productivity of fibrinolytic enzyme and mucilage.
摘要:
A program method of a nonvolatile memory device includes applying a program voltage to a selected word line, applying a first pass voltage to at least one word line adjacent to the selected word line, applying at least one first middle voltage lower than the first pass voltage but higher than an isolation voltage to at least one word line adjacent to the word line receiving the first pass voltage, applying the isolation voltage to a word line adjacent to the word line receiving the first middle voltage, applying at least one second middle voltage higher than the isolation voltage but lower than a second pass voltage to at least one word line adjacent to the word line receiving the isolation voltage, and applying a second pass voltage to at least one word line adjacent to the word line receiving the second middle voltage.
