Detailed explanation-1: -"The buoyant density of pure bacterial cultures ranged from 1.035 to 1.093 g/cm, and their dry-matter content ranged from 12 to 33% (wt/wt)."

Detailed explanation-2: -Microbial dry weight is a standard biomass parameter in research and production settings. The traditional method for its determination using ovens is time consuming and tedious, requiring equilibration between drying and weighing.

Detailed explanation-3: -Determination of the dry mass of the bacteria requires measuring the same cell in two fluids of different density. This technique provides high mass resolution (<1 fg), however is technically complex.

Detailed explanation-4: -dry weight determination: advantages-only way to determine growth of filamentous bacteria. disadvantages-cumbersome, not very accurate, If cell numbers important must relate weight to total cell count number.
