The microbial consortium has been enriched on mineral salt medium under aerobic conditions. I have tried by measuring OD600, dry weight concentration, and viable cell count. Since the consortium aggregates, I think that I am not taking the representative samples each time when I analyze the samples to check the growth each day. Moreover, as I am using mineral salt medium it may not be reliable to measure OD600 to check the growth. Thus, it would be a great help if you can suggest any method which I can follow to take representative samples every time and also any method which is most reliable to check the growth of my microbial consortium. Thank you so much in advance.
