Spectrophotometer calorimetric
method yield optical density (OD) with regard to the
microbial biomass density. The microbial cell density was varied in
the range of 5.24 106 to 9.14 109 CFU mL1 for EM and 1.22 106
to 4.88 107 cell mL1 for MA. MA cell density was determined
using Syringe Liquid Sampler Particle Measuring System SLS-PMS
(PMS, USA).
