The synthesis of ethylene by cauliflower floret tissue was increased when the tissue was inoculated with the soft-rot bacterium Erwinia carotovora. This effect was clearly associated with the production of pectic enzymes by the micro-organism. These enzymes, acting together with the plant enzymes, stimulated the production of ethylene from methionine. The increased synthetic activity was due to the release and increased activity of a glucose oxidase enzyme apparently attached to plant cell-wall material and liberated by the action of pectic enzymes of the bacterium.
用软腐细菌胡萝卜软腐欧文氏菌接种花椰菜小花组织后，该组织的乙烯合成量增加。这种效应显然与微生物产生的果胶酶有关。这些酶与植物酶共同作用，刺激了由甲硫氨酸生成乙烯的过程。合成活性的增加归因于一种葡萄糖氧化酶的释放及其活性增强，这种酶显然附着在植物细胞壁物质上，并因细菌果胶酶的作用而释放出来。
