Cyanobacteria Nutrient Bioavailability and Biomass Productivity Under High Alkalinity

A study from the University of Calgary measured nutrient bioavailability and uptake by a cyanobacteria consortium cultivated at high pH (>10.4) and alkalinity (0.5 M). It reports maximum biomass productivity of 153 mg-AFDW L⁻¹ d⁻¹ and a derived stoichiometric chemical formula for the biomass. The dataset likely contains results from cultivation experiments, including elemental composition and nutrient availability analyses.

Use Cases

• Modeling microbial growth stoichiometry based on reported chemical formula CH₁.₇₅ N₀.₁₇ O₀.₄₁ P₀.₀₀₃
• Optimizing spent medium recycling in cultivation systems based on nutrient bioavailability findings
• Assessing biomass productivity potential for carbon capture technologies under high pH conditions
• Analyzing the impact of precipitate formation on the availability of Mg, Ca, and Fe in alkaline media

Strengths

• Reports specific, measured productivity figure of 153 mg-AFDW L⁻¹ d⁻¹
• Identifies specific nutrient limitations (Mg, Ca, Fe) due to precipitate formation
• Provides a concrete stoichiometric formula derived from experimental data

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
