[Mutation effect of ultra high pressure on microbe].
(Ultra) high pressure had many influences on microbe. It could regulate the expression of gene and protein, influence DNA's structure and function as well as change cell morphology and cell component. These effects not only make (ultra) high pressure to be applied into food sterilization, conserving and some processing, but also indicate it would play an important role in mutagenic breeding of microbe. Pressure can change the structure and function of microbe, yet it is possible that (ultra) high pressure could induce mutation of microbe. Now the feasibility of (ultra) high pressure's mutation effect was discussed according to the effects of it on microbe, some examples and author's studying.
