We haven't yet sat 1B as it is a smaller module, and therefore count's for less percentage of our overall mark, so as a school we tend to leave that till last, as it is quite likely that you will not need to retake it, so I am not so familiar with what is in the 1B syllabus however, I am retaking B3 today, and would like to know, if you, or am I supposed to, know stuff about spontaneous generation and batch production of microbes?
I don't do modules, but I'm taking the AQA B3 exam today and for that exam you do need to know that before the theory of biogenisis was discovered (the theory of organisms being made by other organisms) it was widely believed that organisms just "appeared" spontaneously and that was how they came into being.
For the AQA B3 exam we also have to know a bit about the difference between continuous and batch generators for biogas. I'm not entirely sure about the batch production of microbes.
I agree with M, you have to know a little bit about the history and discovery of microbes etc. I think it would be useful to know about batch production of stuff like Mycoprotein which is all based around the idea of mass production of a bacterium called Fusarium.
The only time i have seen any sort of mass production style questions is when it has been linked with the mycoprotein. :)
