Reviewer 1 Report
The use of ssf for laccase production is an interesting topic and the new research developed in the area makes a review necessary.
I like the information included in the tables.
The major drawback of the article is the English language, I would recommend to use the edition services from the journal or have the article reviewed by a English speaking author.

Response 1: Thanks for your kind suggestion. Based on your comment, the language of this manuscript has been edited by the Specialist editing provided from the MDPI English Editing Service.
Reviewer 2 Report
The processing of agricultural wastes using solid-phase fermentation has been known for more than 50 years, but interest in it has resumed as a method for enzymes production. Therefore this review is modern and relevant, it has been written using references of the most recent years, the material has been fully analyzed and will be useful for a wide range of microbiologists and biotechnologists.
I have a small number of comments:
lines 146-147 instead of “… on the effect of carbon source on laccase, because…”
to write “… on the effect of carbon source on laccase production, because… “
Lines 156-157 this phrase is incomprehensible, it must be clarified
Table 2 - 4 g/12 mL and 1g/ 9gs are not concentrations
Table 4. Column “Fungus” is not correct because there are another microorganisms (ex, Lysinibacillus sp.)

Response 2: Thanks for your kind suggestion. It has been revised.
Point 3: Lines 156-157 this phrase is incomprehensible, it must be clarified.
Response 3: Thanks for your kind suggestion. This sentence has been rewritten and more information has been added.
Point 4: Table 2 - 4 g/12 mL and 1g/ 9gs are not concentrations.
Response 4: Thanks for your kind suggestion. The concentrations have been calculated and revised in Table 2.
Point 5: Table 4. Column “Fungus” is not correct because there are another microorganisms (ex, Lysinibacillus sp.).
Response 5: Thanks for your kind suggestion. Since this review focused on fungi, the cited content about Rheinheimera sp. and Lysinibacillus sp. has been deleted from Table 4.
Reviewer 3 Report
Microorganisms – review mdpi, Wang et al.
The authors present a synopsis and review current findings related to the production of fungal laccase from lignocellulose containing agricultural wastes using solid-state fermentation. The exhaustive review covers call current and relevant literature comparing types of starting material and fermentation types.
While the review is complete in discussing content related to recent advances in laccase production technology the comments relate mainly to organization and readability.
Abstract:
Line 22 – SSF – run on sentence
Introduction:
Organization – key line 88 – Here….summary of what is presented
English needs re-tooling – examples (not exhaustive list)
Lines 47/51/70/93/107/142/146/178-179/200-201/383/426-427 – tense, plural, not complete sentences.
Lines 321 – In recent literatures – English – i.e. Recent reports
Re-structure Table 1 line 135 – Cultivation vessel – include volume, Period (define – days is assumed but not listed) define enzyme substrate in footnote (ABTS – define in footnote ^ABTS - 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid)
Reference needed – line 141
Table 4 – volume for scale of cultivate
Sentence starting line 229 describing table 4 is unclear
Line 322 – define short time
Line 346 – define – It what is “it” referring
Lines 365-366 – dye can cause mutations as they are mutagens – what type of aberrations are the authors describing here, chromosomal?
