Područje primjene nacrta:

This document describes a method for determining the total protein content of algal biomass. 
Therefore, an existing method for measurement and calculation will be adapted.
The method consists of the measurement of the nitrogen content by a practical test method and the calculation of the protein content by a coefficient.
The document will describe the test method for nitrogen measurement. 
As the coefficient usually used for protein determination (6.25) is too high for algae, the document will give a recommendation for a coefficient which is more specific to algae and thereby more accurate.
