Gas vesicles
The topic has significant coverage from independent sources for a long period of time, dating from the first discovery of the gas vesicle gene: gvpA to newer sources from 2017.Many of those sources are from reputable publishers such as the Microbiological Reviews journal. The study on gas vesicles has made an impact on our understanding on bacterial motility and subsequently virulence,which warrants its notability.(1)Recently, there has been research on using gas vesicles as a drug delivery system, which showcases the importance of this topic in medical research.(2)

There are some flaws in the section for "functions", which leads the reader into thinking that gas vesicles are just mainly used for photosynthesis.Gas vesicles have a lot more functions in bacteria other than positioning in the water column for optimum light capturing.In certain bacteria, gas vesicles help maintain optimum salinity by positioning the organism in specific locations in a stratified body of water to prevent it from drying out.(3) Also,some serve as a specific regulator in quorum sensing in association with the development of flagella.(4) To summarize, there is basically a lack of information to truly portray the importance of gas vesicles in bacteria. The article only mentions one type of usage in photosynthetic bacteria. In the section for growth, the writer indicates that it is unclear whether a molecule interfering with Gvpa will change the shape of gas vesicles. New research has shown that a single point mutation of a non-polar residue in Gvpa resulted in a change in shape of gas vesicles from spindle-shaped to cylindrical shaped.

Improvement may be made in the "functions" section, by summarizing the fact that gas vesicles play a role in the motility and positioning of bacteria, usually in a body of water. Then, branching off to mention the significance of such positioning.Adding sections in photosynthesis, osmotic regulation, and quorum sensing. Examples in different bacteria can be mentioned to aid understanding. For example, in enterobacterium, Serratia spp. ATCC39006 (S39006), gas vesicle production plays a role in quorum sensing.(5)

In general, the information added is relevant.Language is easy to understand, with balanced coverage and neutral content.The added section on taxonomy for example, greatly improves the clarity of currently identified species in methanobacteria. In terms of structure,it is not clear whether the author intends to keep the "References" section with the NCBI webpage in the original article. I would suggest just including the NCBI webpage in the external links section at the end of the article as it makes more sense to keep all extra references in one place.Sources are scholarly and is linked to each relevant sentence.Content added is well sourced and includes up to date information about applications of methanobacteria.For example, information about using methanobacteria to improve efficiency of energy generation from renewable sources or energy. Moving on to specific sections.For the methanobacteria section, I would suggest explaining why the term bacteria is included in its name despite being Archae, just so that the article reads more clearly. The author could perhaps briefly explain in one sentence about RNA sequencing, and how this helped differentiate archae from bacteria.For the biotechnology section, more detail is needed since it should read clearly to someone without any background in science. For example,more detail could be added to explain how mineral deposits help prevent corrosion : by preventing the metal's contact to air and water.A brief reference from the research article can also be made to explain how the mineral deposits are formed: methanobacteria extract electrons from the metal surface and induce carbonate precipitation, forming a casing. Also, the authors presentation of Methanobacterium palustre from the quoted source is not clear. From the referenced research,the major benefit of electromethanogenesis is to increase the energy efficiency of methane production as compared to traditional methods like a plain carbon cathode. Also, electrical current produced from renewable energy sources is being stored into methane. The authors writing on this seem to imply that methane is the renewable energy source and not the product of the reaction. All in all a good article, but it needs more detail in its explanations Honorsc (talk) 19:27, 5 November 2017 (UTC) — Preceding unsigned comment added by Honorsc (talk • contribs)

The content gave great examples and maintained a neutral point of view, but the last sentence about possible applications doesn’t directly pertain to function and may be better suited as its own topic. Also, starting the first sentence saying gas vesicles are used for buoyancy then in the second sentence it is again noted that they can control buoyancy makes the content sound redundant. Other adjustments can be made to the structure as there were three points about positioning of the cell, for enhanced location for photosynthesis, oxygen level and optimum salinity and it might be more efficient to list those together and list everything about buoyancy together instead of switching between the topics. This would help to keep the writing concise by introducing and supporting one concept before moving to the next. The structure of the article was efficient at portraying the material and was cohesively displayed. The article is written well and is concise with each point, which was the best quality of the article. A minor topic that can be further explained is when it is brought up that the cell positions itself for optimum salinity so that the cell doesn’t dry out, it is not clear to the reader how it could “dry out” in water. There were a few commas that didn’t have correct spacing, other than that there were no apparent grammatical errors. It was great that the article didn’t rely on few sources, there were many integrated without signs of close paraphrasing. The second source was very well summarized and a reliable source and was awesome at supporting quorum sensing and gas vesicles. However, the third reference pertained more to how Annamox microbes adapt using compatible solutes instead of positioning, so it is not obvious how this reference relates to gas vesicles.
