Proteomic Data on Lysinibacillus PET Biodegradation Potential

Proteomic analysis reveals a Lysinibacillus strain isolated from Icelandic soil responds to PET plastic through oxidative-stress proteins and metabolic enzymes, not canonical PET-degrading enzymes. The dataset compares its early-stage growth performance against the reference strain Ideonella sakaiensis over a six-week period. It contains proteomic characterization data from MALDI-TOF MS analysis and in silico screening results.

Use Cases

• Compare the expression levels of oxidative-stress response proteins like peroxiredoxins and superoxide dismutases between PET-exposed and control conditions.
• Analyze the proteomic profile for the presence of hydrolases and assess their lack of the GXSXG motif or Ser-His-Asp catalytic triad.
• Correlate FE-SEM surface alteration observations (erosion, fissures, delamination) with the expressed proteomic data to infer degradation mechanisms.
• Benchmark the early-stage growth data of Lysinibacillus sp. against Ideonella sakaiensis across the six-week experimental timeline.

Strengths

• Data is derived from a multi-method study combining proteomics (MALDI-TOF MS), in silico screening, growth assays, and surface imaging (FE-SEM).
• Includes a direct six-week comparative growth analysis with the established PET-degrading reference strain Ideonella sakaiensis.
• Released under the permissive CC BY 4.0 license, facilitating open reuse and sharing.

Limitations

• The dataset is very small at 14.4 KB, indicating limited scope and likely a summary table rather than raw experimental data.
• Proteomic analysis did not detect canonical PET-degrading enzymes (PETase, MHETase), limiting its direct applicability for enzyme discovery.
• Spatial coverage is limited to a single bacterial strain isolated from Icelandic soil, reducing generalizability.
