摘要
通过扫描电镜观察到低温空气等离子体诱导酿酒酵母产生一种特殊的“空洞”形细胞。空洞细胞的形态特征及生长特性提示,空洞的形成可能是由于低温空气等离子体所致的细胞诱变效应,而不是等离子体对细胞表面的直接损伤。结果提示低温空气等离子体对细胞的损伤及诱变作用可能具有复杂的作用机制。
A special cell morphology, cavity-like cells, was found in posterities of Saccharomyces cerevisiae treated by low-temperature air plasma with different powers. The feature of the special morphology indicates that the cavity-like cells may be formed by cellular mutation effect induced by the plasma, instead of direct cellular damage by the plasma. The results suggest that the cellular mutation effect of the low-temperature plasma is a complex process.
