Unclear

I'm working on copyediting, but some sections of the article are so confusing I have no idea what is intended to be said. The section about carbon cycling is especially unclear. Looking at the only cited source was not helpful and also seemed to indicate that the section was more pertinent to Lost City Hydrothermal Field. No mention of formatotrophs or formate on the cited source. - Popoki35 (talk) 13:06, 25 December 2021 (UTC)[reply]

Copyeditor/biologist #2 here. It's not just you -- I couldn't make head nor tail out of that either. I did what I could with it and deleted the rest. So people don't have to go digging around in the history, here are the 2 paragraphs from the original:

Cycling carbon metabolic pathways through formate and additional enzymes like formate transporters, and carboxysomes probably implicated in the concentration of CO₂ that provide carbon source for the entire biofilm formed over the chimneys.This finding showed some evidence about how would be the carbon cycling in a place were the support of energy of the ecosystem is based on geochemical reactions and might help to explain how life in earth was sustained in early evolution.^[1] Similarly studies of carbon assimilation strategies in ultrabasic groundwater mediated as well by serpentinization explored the chemosynthesis microbial reactions in the subsurface of wells into the ultramafic Coast Range Ophiolite Microbial Observatory (CROMO) found that the microbial communities present in those aquifers use the products of serpentinization as carbon source, including formate and methane.

The low ionization potential of formate makes it a good electron donor to provide reducing power to microorganisms. Some studies discuss how the production of formate by electrosynthesis - an abiotic process - integrated with a biotic process that used it as a carbon source. To support the growth of formatotrophic microorganism can feasible to produce highly valuable chemicals and highlighted the difficulties the development of the technology. As mentioned above few formatotrophs have been studied, thus the actual trends for fermentation of formate are focused on the development of synthetic pathways or matching enzymes from different microorganism to create totally new pathways. and the improving of catalytic activities by directed evolution techniques. It has been proposed a pool of at least twelve new pathways to assimilate formate, whether by using existing formate fixing reactions or by synthesis of de novo enzymes into biofuels and valuable products or single cell protein.

Separately, is the xylulose 5-phosphate pathway different from the reductive pentose phosphate pathway? It sounds like 2 names for the same thing to me, but IANAE. Gould363 (talk) 23:22, 23 January 2022 (UTC)[reply]
