Abstract: Abstract: When the yeast treated by the static electricity field (0、20、40、60、80、100、120second） have cultured, take a part to continue to handle with the same method, carried on 4 rounds in a row, then measured all posterities, probed the biological effects treated by the static electricity field. It is showed that inside 80 second in the static electricity field, can promote the growth and reproduction of yeast cell, the content of soluble sugar and protein and nucleic acid etc also has different degree increment. As the handling time over 100 second, the yeast cell breed were inhibited. After using a same method to for many rounds handle, the yeast cell adapts the environment changes gradually.
