“…Our proposed model of CH 4 migration into CVL from petroleum basins not only provides sufficient CH 4 , but also agrees with proposed pathways of sulfur migration into CVL (Rosales Lagarde et al, 2014). The entrance of thermogenic CH 4 into CVL also agrees with observations of CH 4 and longer-chain hydrocarbons emanating from ''Group II'' springs of the Sierra de Chiapas region northwest of CVL (Nencetti et al, 2005).…”

“…Alternative electron acceptors such as O 2 , and nitrate (NO À 3 ) are known to be metabolically coupled to CH 4 oxidation in other environments (Hu et al, 2011;Mattey et al, 2013). However, O 2 and NO À 3 concentrations in the anoxic springs of CVL were below detection in previous studies, where the concentration of each was , 0.1 mg L À1 (Hose et al, 2000;Rosales Lagarde et al, 2014). Addionally, organoclastic sulfate reduction competes with anaerobic CH 4 oxidation only when organic matter is abundant (~1 % by sediment weight) (Malinverno and Pohlman 2011;Pohlman et al, 2013), and the organic carbon concentration in CVL spring water is comparatively low, ranging from 0.5 to 3.5 mg L À1 (Rosales Lagarde, 2013).…”

Methane (CH 4 ) is an economic resource and a greenhouse gas, but its migration through rocks is not immediately associated with speleogenesis. Sulfuric-acid speleogenesis is a cave-forming mechanism that has produced a variety of economically important oil fields and aquifers, and is theorized to be related to the oxidation of CH 4 and hydrocarbons. Despite hypotheses that the oxidation of CH 4 may provide a basis for the generation of sulfides during sulfuric-acid speleogenesis, evidence from active systems has not yet been obtained.

“…Metagenomics, as a next-generation sequencing (NGS) field, offers a modern way to determine community structure, species diversity, metabolic capacity, and functional diversity studies [ 3 , 26 , 27 ]. The NGS technologies, including 454 and Illumina sequencers, use oligonucleotides to amplify the rrs gene encoding for the 16S rRNA subunit and are targeted to hypervariable regions.…”

New biotechnology applications require in-depth preliminary studies of biodiversity. The methods of massive sequencing using metagenomics and bioinformatics tools offer us sufficient and reliable knowledge to understand environmental diversity, to know new microorganisms, and to take advantage of their functional genes. Villa Luz caves, in the southern Mexican state of Tabasco, are fed by at least 26 groundwater inlets, containing 300–500 mg L−1 H2S and <0.1 mg L−1 O2. We extracted environmental DNA for metagenomic analysis of collected samples in five selected Villa Luz caves sites, with pH values from 2.5 to 7. Foreign organisms found in this underground ecosystem can oxidize H2S to H2SO4. These include: biovermiculites, a bacterial association that can grow on the rock walls; snottites, that are whitish, viscous biofilms hanging from the rock walls, and sacks or bags of phlegm, which live within the aquatic environment of the springs. Through the emergency food assistance program (TEFAP) pyrosequencing, a total of 20,901 readings of amplification products from hypervariable regions V1 and V3 of 16S rRNA bacterial gene in whole and pure metagenomic DNA samples were generated. Seven bacterial phyla were identified. As a result, Proteobacteria was more frequent than Acidobacteria. Finally, acidophilic Proteobacteria was detected in UJAT5 sample.

“…Current sulphide-rich environments including sediments, water columns and areas around vents are found in marine and freshwater environments around the globe. For example, hydrogen sulphide concentrations can reach up to 15,000 μM in the pore waters of sediments off the coast of California, up to 6,500 μM around the hot vents of the East Pacific rise, or up to 800 μM in fresh water springs in Mexico (Bagarinao, 1992;Oeschger and Vetter, 1992;Rosales Lagarde et al, 2014). More temporary, but recurring Journal of Experimental Biology • Accepted manuscript sulphide-rich events have been observed off the coast of Peru with up 6 μM sulphide (Schunck et al, 2013) and Namibia (up to 30 μM sulphide) which leads to regular mass mortalities of fish (Copenhagen, 1953;Lavik et al, 2009).…”

Ecological communities and biodiversity are shaped by both abiotic and biotic factors. This is well illustrated by extreme environments and invasive species. Besides naturally occurring sulphide-rich environments, global change can lead to an increase in hydrogen sulphide episodes that threaten many multicellular organisms. With the increase in the formation, size, and abundance of oxygen minimum zones and hypoxic environments, bacterial-associated sulphide production is favoured and as such hydrogen sulphide-rich environments increase subsequently. Many species are challenged by the inhibiting effect of sulphide on aerobic energy production via cytochrome c oxidase, ultimately causing the death of the organism. Interestingly, many protist, yeast, plant, and also animal species possess a sulphide-resistant alternative oxidase (AOX). In this study, we investigated whether AOX is functionally involved in the sulphide stress response of the highly invasive marine tunicate, Ciona intestinalis. At the LC50, the sulphide-induced reduction of developmental success was three times stronger in AOX knock-down embryos than in control embryos. Further, AOX mRNA levels were higher under sulphide than control conditions - and this effect increased during embryonic development. Together, we found that AOX is indeed functionally involved in the sulphide tolerance of Ciona embryos, hence, very likely contributing to its invasive potential; and that the response of AOX to sulphide seems to be controlled at the transcriptional level. We suggest that AOX-possessing species play an important role in shaping marine ecological communities, and this importance may increase under ongoing global change.
