Those three... and "batched over several days"? I'm not sure if that's a condition or not.

I've never come across an exam asking 5! I was going to add the sterile conditions one like potter said - saw that in a mark scheme

ive only come across 4.

-yeast (containing enyzmes)
-temperature around 30°C
-anaerobic conditions (no oxygen in air)
-batch process

most of the time, they only ask for 1 or 2 conditions. i put the top two down first coz they the most obvious.
sometimes they may be expecting all possible conditions. this is the case in big mark questions.
