Chemistry Correction for “High-throughput experimentation for discovery of biodegradable polyesters,” by Katharina A. Fransen, Sarah H. M. Av-Ron, Tess R. Buchanan, Dylan J. Walsh, Dechen T. Rota, Lana Van Note, and Bradley D. Olsen, which published May 30, 2023; 10.1073/pnas.2220021120 (Proc. Natl. Acad. Sci. U.S.A. 120, e2220021120).
The authors note that on page 7, right column, fourth full paragraph, line 4, “prepared by adding 40 g of agar to 500 mL MilliQ and autoclaving” should instead appear as “prepared by adding 20 g of agar to 500 mL MilliQ and autoclaving.” The online version has been corrected.
The authors also note that SI Appendix, Fig. S1 and Table S1 and Dataset S4 appeared incorrectly and that an error in the smiles string for diglycolic acid was identified. There is a missing “C” in the SMILES which should read “C(=O)COCC(=O)” in SI Appendix, Fig. S1 and Table S1 and Dataset S4. A translation error from digital data to tabulated information in Dataset S3 for “Biodegradability” was additionally rectified. These errors were only found in the tables and were not present in the digital data used for analysis. The SI Appendix has been corrected online.
