Antarctic Microbial Protein Extracts for Cryoprotection of Cells and Viruses

Supplementary file 1 contains data from a study on cryoprotective protein-rich extracts from Antarctic microorganisms. The dataset likely includes results from screening 22 bacterial and yeast isolates and evaluating extracts for preserving Escherichia coli, HEK293 cells, and adenovirus over 30–60 days. The data was authored by Joana Camila Lopes and last updated on 2026-04-28.

Use Cases

• Identify promising Antarctic microbial strains for cryoprotection based on survival rate screening data.
• Evaluate the efficacy of intracellular versus extracellular protein extracts for preserving prokaryotic cells based on viability results.
• Assess the cryoprotective activity of specific protein extracts on eukaryotic cell lines based on viability maintenance data.
• Analyze the stability of viral titers over time when treated with different microbial protein extracts.

Strengths

• Data is derived from a controlled study screening 22 distinct Antarctic microbial isolates.
• Results include specific quantitative outcomes, such as a 3% increase in E. coli viability and maintenance of HEK293 cell viability above 20%.
• Experimental evaluation covers multiple biological systems: prokaryotic, eukaryotic, and viral.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 3.9 MB PDF, which may require extraction or conversion for analysis.
