Correction to: Nature Biotechnology https://doi.org/10.1038/s41587-022-01258-6, published online 16 March 2022.

In the version of this article initially published, there was a misstatement regarding the production of Modern Meadow’s leather alternatives. The company uses plant-based proteins for these products, and not fermentation. Descriptions have been amended in the first, fourteenth and fifteenth paragraphs, and in Table 1. The changes have been made to the HTML and PDF versions of the article.
