Characterization and Biological Activities of Yeasts Isolated from Marine Environments

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In this study, the authors meticulously isolated and analyzed 11 marine-derived yeasts through both phylogenetic and phenotypic examinations. The investigation delved into their bioactivities, encompassing antioxidant, antibacterial, and tyrosinase inhibition activities, shedding light on potential industrial applications. While the study design is commendable and the data robustly support the findings, there are areas that warrant additional clarification and refinement. The following concerns and suggestions aim to enhance the study's overall rigor and depth.

 

Specific Comments:

 

1.      Reference strain for variations in phylogenetic and phenotypic traits:

It is advisable to incorporate a reference lab strain when studying the variations in phylogenetic and phenotypic traits of the marine-derived yeasts. This inclusion would serve as a valuable point of comparison, aiding in the comprehensive understanding of how these traits differ or align with established yeast strains.

 

2.      Ecological implications in marine environments:

 The discussion section is a prime opportunity to explore the ecological implications of the identified yeast species within marine environments. A more thorough exploration of specific adaptations or characteristics that render these yeasts well-suited for marine habitats would provide valuable context. Understanding how these yeasts thrive in marine conditions could contribute to broader ecological insights and potentially guide future research directions.

 

Comments on the Quality of English Language

The overall quality of English in the paper is generally good. The language is clear, and the writing is coherent, allowing for easy comprehension of the study.

Reviewer 2 Report

Comments and Suggestions for Authors

The manuscript "Characterization and Biological Activities of Yeasts Isolated from Marine Environments" presents interesting research results regarding the search for new yeast isolates with high biotechnological potential. This is a current topic due to the constant search for yeasts that can be used in industry. A very interesting methodology was used for preparing and testing yeast extracts. I have not seen such tests before, but I think they are good and innovative. The results are very well described and discussed with other authors.

Detailed notes:

line 49, 341 - Phaffia and Xanthophyllomyces are the same genus (Phaffia is the name of the anamorphic form).

Chapter 2.6 - please refer to the literature.
