A Review of the Strategic Use of Sodium Alginate Polymer in the Immobilization of Microorganisms for Water Recycling

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The review paper offers some interesting and significant newer insights into the application of this assorted class of sodium alginate polymer for varied water recycling applications, and hence I reservations recommend its acceptance after addressing the main concerns:

1. When it deals with water recycling applications, authors should better explain how sodium alginate polymers have their unique advantages in these three aspects and provide some examples.

2. Please reframe the future perspective and conclusion section

3. Also, try to include one small conclusive remark after each main section. This will strengthen the review.

4. Some work on the regarding water pollution by using different materials, such as Sol. RRL, 2023,7, 2300143; Molecules 2023, 28, 4507 and Molecules 2023, 28, 6848.

5. Authors may look into it. Also, what are the pros and cons of sodium alginate polymer?

6. I feel texts and symbols in Figs have poor quality, please enhance if possible.

Reviewer 2 Report

Comments and Suggestions for Authors The summary of few different papers is not good enough unless you summaries a finding from their collective findings and based on that should be able to make few suggestions/comments/recommendations of your own. 1. A summary of the main recent progresses and remaining challenges of the usual characterization techniques should be given including recent publications. 2. A sub-section should be created to discuss the intrinsic and specific properties/features of polymers that makes them suitable to be used as a new materials in improving water quality, preserving. 3. I suggest the author could give a sub-section should be created to provide general/specific synthesis procedure for polymer and then discussion on how these strategies influence the properties of the polymer.

4. Some refs may be considered, such as CrystEngComm, 2019, 21:4578-4585; Coord. Chem. Rev., 2020, 406, 213145; CrystEngComm, 2021, 23, 741–747

The summary of few different papers is not good enough unless you summaries a finding from their collective findings and based on that should be able to make few suggestions/comments/recommendations of your own.

Thank you very much for your time spent reviewing this document, as well as your valuable recommendations regarding this manuscript. I have carefully reviewed your observations and have made the necessary modifications.

1. A summary of the main recent progresses and remaining challenges of the usual characterization techniques should be given including recent publications.

I sincerely appreciate your attention to this detail. Text has been added to the section Sodium alginate as adsorbent, as well as to the last section.

2. A sub-section should be created to discuss the intrinsic and specific properties/features of polymers that makes them suitable to be used as a new materials in improving water quality, preserving.

I sincerely appreciate your attention to this detail. I have added the requested information in subsection 3 (and two new references).

3. I suggest the author could give a sub-section should be created to provide general/specific synthesis procedure for polymer and then discussion on how these strategies influence the properties of the polymer.

I appreciate the suggestion. I have taken into account the recommendations and have incorporated text and an additional image (Image 2) providing a synthesis procedure of the polymer in question.

4. Some refs may be considered, such as CrystEngComm, 2019, 21:4578-4585; Coord. Chem. Rev., 2020, 406, 213145; CrystEngComm, 2021, 23, 741–747.

I sincerely appreciate your suggestion to consider other works related to various materials. I have reviewed the recommended articles and have added them to the document:

Reviewer 3 Report

Comments and Suggestions for Authors

1. I would recommend to mention source of microorganism, the plant details (Case Study section, raws 441-442).

2. Raw 491: I would recommend to include references as well after words "when compared with data reported in alternative studies".

3. In case authors repeated the experiments for statistics, would be good to include error bars in Figure 4a.
