If you pick up this book with the intention of learning downstream processing without any help from a teacher, good luck. I'd probably advise you to pick another book. I find that this book is bearable if you've already got a good hand on the topic, but when you step into this reading experience with no knowledge, you're, frankly, a bit screwed. There will be explanations without definitions of the thing that the explanation is about, which makes the explanation hard to impossible to understand. Some equations will even only appear in examples and never be explained. The language is dry and often redundant. The mathematical inductions, or whatever is the right term, are lacking and often the parts of equations are too swiftly defined. Not to mention the annoying wording of the problems.
I'm sure this book was made by fine engineers and scientists, and it most certainly holds a lot of valid, interesting, on-point information. It's just really, really hard to get to. If you already get downstream processes, it might be a good reference work.
Untuk pemula di bagian bioengineering, buku ini sudah cukup untuk menjelaskan secara sekilas tahapan tahapan untuk mendapatkan produk dari suatu agen hayati. Dan buku ini juga memberikan contoh soal ataupun gambaran suatu rancangan pabrik agar pemula dapat membayangkan apa yang diterangkan oleh teori sebelumnya
