Mouse Acidic Chitinase Effectively Degrades Random-Type Chitosan to Chitooligosaccharides of Variable Lengths under Stomach and Lung Tissue pH Conditions
Round 1
Reviewer 1 Report
In this manuscript of "Efficient production of variable length chitooligosaccharides from random-type chitosan using mouse acidic chitinase" authors prepared heterogeneously (block-type) and homogenously (random-type) deacetylated molecules and declared that mouse Chia digested chitosan into various chitooligosaccharides depending on the mode and degree of its deacetylation. As a whole, the manuscript lacks of novelty, the experimental design is relatively single and the content and results are not rich enough. Thus, it is suggest to reject the manuscript since the draft cannot reach the level of molecules.

Response to Comment 1: Thank you for your comments. We further improved our original version based on all Reviewers’ comments and suggestions to show more profoundly the indicate novelty of our study in title, abstract and discussion in the revised version.
Reviewer 2 Report
In current study Wakita et al demonstrates that acidic chitinase produces chitooligosaccharides with higher efficieny and size variability from random-type chitosan when compared with the block-type form of the chitozan and propose explanations for observed experimental results.
Minor remarks:
- Generally manuscript is well written, however the text should be checked for grammatical and stylistic errors.
- The introduction and discussion section should be expanded with description of perspectives and practical implications of the findings. The limitations of current study should be added to the discussion of the article.

We also included the limitations of the current study in the discussion in the revised version.
Reviewer 3 Report
Please mention clinical significance of this study.
Minor suggestion is to mention the rationale of study more clearly in abstract and conclusion.
