Dear Dr. Kothe,

Thank you for submitting your manuscript “Calcium carbonates: Induced biomineralization vs. controlled macromorphology?” to Biogeosciences. Two expert reviewers and I have assessed your submission and feel that it is acceptable for publication as it addresses important questions on the diversity and extent of microbial calcite and vaterite biomineralization. Overall, this is a nice contribution and advances our knowledge. However, the reviewers and I also identified numerous items that need to be addressed to improve the manuscript.
At this stage of the review process, I am providing the post-discussion editor decision which would normally be followed by revision. However, you have already revised your paper according to the reviewers’ comments which puts you ahead of this step.
I have evaluated your revised manuscript and provided additional comments to be addressed in the attached, marked up PDF. My comments are more extensive than the reviewers and are aimed at improving readability and also linkages to earlier work by the group (e.g., Meier et al. 2017). In addition, the methods are lacking quite a bit of detail and references which needs to be remedied. The reader should be provided enough information to be able to repeat your study, without excruciating detail.
At this point, I ask that you please revise your paper based on my comments and resubmit for further review. In addition, please submit a version of your paper so all changes marked as track changes.
Please feel free to contact me with any questions.

Sincerely,
Dr. Denise M. Akob
