Unified Field Study 2 (UFS-2)

Description

The Unified Field Studies (UFS), established by the Algae Testbed Public-Private Partnership (ATP3), produced data on the effect of environmental and process conditions on algal growth rates and algal composition. The goal of the second Unified Field Study (UFS-2), performed April to May 2014, was to generate a robust inter-testbed dataset in algal biomass and lipid productivity and yield for the algal strain Nannochloropsis oceanica KA32 as a function of different regional, and environmental conditions among sites by controlling non-geographical-related variables including production systems, production process and protocols, system scale, and algae strain.

5.2 UFS-2 Compositional Analysis Data.csv CSV The data include the lipid (FAMELipids.AF), protein (Protein.AF) and carbohydrate (Carbohydrates.AF) content of biomass harvested from the ponds throughout the cultivation experiment and immediately freeze-dried. All data presented here are averaged over technical replicates and expressed as percent (%) on an ash-free dry weight basis of harvested biomass. Some data points are missing due to either data not meeting the rigorous QC requirements or experimental errors during data collection. Open resource
