In a separate question I've described my general experimental setup where I need to measure the number of live cells in a growing bacterial culture in a fairly rapid and high-throughput manner. In that question I'm asking if there are any alternatives to the gold standard of CFU plating for making this measurement. As I wrote that question, it occurred to me that if I could just make CFU plating easier to do with lots of samples (esp. using fewer plates), then this method could work just as well. So my question here is if there is a way to make CFU serial dilution plating easier when I have to measure the number of live cells in 7+ different growth conditions every hour of growth?
