Question

Downstream processes can be characterised by two parts: recovery and purification.
Recovery being the part where the product is separated from the biomass (primary
separation) and concentrated by a membrane process or a catcher step where the
product is bound to a chromatographic matrix and eluted in high concentration

Answer 1

下游工序可被分为两个部分：恢复和净化。
恢复这项工序是将产品从废弃物中分离（原始分离物），并集中半透膜过程或者通过色谱矩阵和高浓度脱洗进行捕捞步骤。
累累~~这个好像化工中的提纯过程，分离提纯。翻译的不好，理解为主。抱歉~~
