Evaluation of three protein methodologies for marine plankton

Abstract

Protein is an important biomass parameter and critical in the enzyme analysis of plankton. When plankton biomass is abundant, obtaining protein samples is not difficult. However, when biomass is a scarce quantity and it needs to be used for many other measurements, obtaining sufficient material for a protein sample is a challenge. If the protein analysis can be made on samples simultaneously prepared for other types of biochemical analyses, this challenge is partially mitigated. The objective of this research was to determine the optimal method for measuring protein content in plankton samples prepared for enzyme analysis.
