    Erm, ok...

    Continuous cultures - advantages: don't have to shut fermenter down as often as for batch cultures - when you shut it down after a batch you have to empty it, sterilize it, refill etc: takes time and hassle. Also as you're restarting the culture each time, with batch cultures you have the lag phase each time, which slows production; with continuous cultures you don't have this problem.

    Disadvantages: continuous cultures aren't always best for producing certain things, eg for the full flavour development of some foods you need to use batch cultures. Also some products are made only when cell growth stops; obviously this doesn't happen in a continuous culture! Finally, contamination can have much more serious effects.

    Hope this helps!

    LOL i don't think you understand I DON'T HAVE THE FRECKIN EXAM PAPER. Why don't you spend this time doing some last minute revision rather than trying to get hold of a paper which I don't have?
