Proteomic Data on Lysinibacillus PET Biodegradation Potential

A 2026 study by Radoslaw B. Dudziak provides proteomic data from a Lysinibacillus bacterial strain isolated from Icelandic soil and evaluated for its potential in polyethylene terephthalate (PET) biodegradation. The dataset contains results from growth assays, proteomics, in silico screening, and surface imaging conducted over a six-week period. It compares the strain's performance against the reference organism Ideonella sakaiensis.

Use Cases

• Analyze the expression of oxidative-stress response proteins like peroxiredoxins and superoxide dismutases triggered by PET exposure.
• Compare early-stage growth assay results between Lysinibacillus sp. and Ideonella sakaiensis across the six-week experimental timeline.
• Investigate the absence of canonical PET-degrading enzymes (PETase, MHETase) through proteomic and in silico genome-wide screen data.
• Examine FE-SEM imaging data for evidence of polymer surface alterations such as erosion, fissures, and delamination.

Strengths

• Data originates from a peer-reviewed scientific study published in 2026, ensuring contemporary relevance.
• Integrates multiple analytical methods: growth assays, proteomics (MALDI-TOF MS), in silico screening, and surface imaging (FE-SEM).
• Provides a direct six-week comparative analysis against the established PET-degrading reference strain, Ideonella sakaiensis.

Limitations

• The dataset is very small (33.4 KB), indicating limited scope, likely containing summary results rather than raw experimental data.
• Proteomic analysis did not detect dedicated PET-hydrolyzing enzymes, suggesting the data may reflect metabolic adaptation rather than direct depolymerization mechanisms.
• Specific sample sizes, row counts, and column structures for the underlying data tables are not provided in the input.
