So that's where we stand at the moment, and I've just got a few final thoughts, which is that this is another way in which biology is now coming in to supplement chemistry in some of our societal advances in this area, and these biological approaches are coming in in very different forms, and when you think about genetic engineering, we've now got enzymes for industrial processing, enzymes, genetically engineered enzymes in food.
这就是我们现阶段取得的成果。 我最后还有几点想法 这是另一种方式，用生物学方法 来补充化学方法， 在某些比较先进的领域 这些生物学方法 都各不相同。 当你想到基因工程 我们现在有供工业制造用的酶， 食物中的基因改造过的酶。
