Reviewer 2

Comment Response

1 The manuscript must include the recent research works on application to protein production systems, especially from the past 5 years We thank the reviewer for this comment. As stated in the manuscript's methods section, we conducted a thorough systematic review of studies published until January 2025, including studies from 1986 onwards. In addition to these studies, we have included some recently published work on protein production in the introduction and conclusion to further strengthen our arguments.

See below for details on the various recent references being added to support our arguments.

Introduction: References 9,10,13,18

Discussion: References 46,51,60-62

2 Introduction Section-Authors should justify here why this study is important and should state the uniqueness of this study.

Thank you for this helpful comment. We now clearly describe the importance of the study and state its uniqueness in the introduction section (see page 3, lines 50-57). We have also included an updated reference to support this (13).

3 Please include the recent references for broad readers to understand the

importance of protein production from various sources and in the industrial applications. Thank you for your suggestion. The paper focuses on livestock-based protein production systems, with two protein innovations (plant-based and cultivated meat). However, as per the suggestions, we have included similar references from various sources, including industrial applications.

See new references, 9,10, 13,18,46,51, 60-62.

4 There are numerous grammatical errors and they significantly affect the flow of ideas. Please check through the MS.

Thank you for this comment. A professional copy editor has proofread the entire manuscript and the supplementary information.

5 Please add line numbers for easy identification of specific lines in the manuscript during review. We have added line numbers to the manuscript.

6 Research would be nice if you could include the latest updates on recent studies. Thank you for your suggestion. We have included the following references in the introduction and discussion sections to support our statements.

See new references, 9,10, 13,18,46,51, 60-62.

7 Check thoroughly all typographical errors and references, and the action should follow the journal guidelines. Thank you for this comment. A professional copy editor has proofread the entire manuscript and the supplementary information.

8 Conclusions need to be elaborated and made clearer.

Thank you for this suggestion. We have now added two main conclusions from our findings in the conclusion section.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
