“…Most of the existing efforts on micritization have been based on geological and geochemical observations, coupled with studies on pure microbial cultures (e.g., del Buey et al, 2023; Garcia‐Pichel et al, 2010; Popall et al, 2020; Sánchez‐Román et al, 2008; Sánchez‐Román, McKenzie, et al, 2009; Sánchez‐Román, Vasconcelos, et al, 2009; Sánchez‐Román, McKenzie, et al, 2011; Sánchez‐Román, Romanek, et al, 2011). Several of these studies have been driven by a rational analysis of metabolic pathways that move electrons and affect alkalinity and have been verified for microbiome taxonomy and functions through the most advanced molecular technologies (Widder et al, 2016).…”

“…Their RuBisCO and carbonic anhydrase enzymes can intensively sequester protons, increasing the local alkalinity and supporting carbonate precipitation. They also produce abundant negatively charged EPS and mucoid sheaths, further promoting carbonate precipitation and crystal nucleation, eventually contributing to grain cementation (Cutts et al, 2022;del Buey et al, 2023;Görgen et al, 2021;Kobluk & Risk, 1977a, 1977bPopall et al, 2020;Robles-Fernandez et al, 2022;Sanz-Montero et al, 2023). However, the presence of photoautotrophs is usually restricted to the first layers of the sediments (0-5 cm depth), and their abundance represents only a limited part of the microbial communities dwelling in carbonate settings (S anchez- Baracaldo et al, 2022;Sørensen et al, 2007).…”

“…It is widely accepted that benthic and, to a lesser extent, planktonic microorganisms can catalyze the nucleation of dolomite in alkaline lakes [9,[11][12][13][14][15][16]. Multiple field and laboratory studies have demonstrated that the precipitation of dolomite at low-temperature occurs in specific metabolic pathways, including sulfate reduction [11,[17][18][19], sulfide oxidation [20], aerobic respiration [21], methanogenesis [22,23], methane oxidation [24], oxygenic [25,26] and anoxygenic [27] photosynthesis, although the mineralization of microbial mats is commonly a result of the interplay between different metabolisms [28].…”
