Fig.1.Effect of infection time by alginic acid decomposing bacte-ria on the production of reactive oxygen species. 标题： 图1.
Beer stali ng was also influenced by the metal ions that act as the catalyst for staling re action. 金属离子的存在能催化自由基反应,金属离子清除剂对啤酒老化也有一定作用。
The production of reactive oxygen species in Laminaria japonica during infection of alginic acid decomposing bacteria was demonstrated universally. 4、海带在褐藻酸降解菌感染下活性氧的产生具有普遍性。
It is known that under appropriate conditions isopropylmagnesium chloride can be provided in the re action of isopropyl chloride with magnesium in THF in>90% yield. 摘要用镁和氯代异丙烷为原料，四氢呋喃作溶剂，在一定条件下合成了格氏试剂，格氏试剂的收率达90%25以上。
