They form balls that get sedimented hence taking OD value is not appropriate and can we look for the spore suspension method or any other methods?
1. Centrifuge down the balls.
2. Wash twice
3. Leave it @ 60 degree in hot oven for 90/120 minutes
4. Take the dry weight
5. Compare dry weight for growth curve and other experiments.

Measure protein is possible way.
You can add some glass beads for liquid growth then measure the OD600 value, but the growth rate would be higher when beads added.
If the detection range is in ng/ml but the reference range is in ug/ml for a molecule or protein in serum or plasma .how to dilute and what is the initial volume to be taken for quantitative analysis
