“…After 7 days of incubation, the broths were centrifuged at 15000 rpm for 10 minutes to separate the supernatant from the cell growth. Sulphate production was measured by adding 1:1 barium chloride solution (10%, w/v) with bacterial culture supernatant followed by mixing the suspensions vigorously (Cha et al, 1999). A resulting white turbidity due to barium sulphate formation was measured at 450 nm.…”

“…These microorganisms were determined to be used in the construction of bio-concretes, crack healing in concretes, and soil bioremediation. In addition, diverse enzyme activities revealed in cave isolates can serve industrial uses with low energy spending [11,22,24,25]. Wastes bioremediation potentials were detected also in cave isolates [5,25].…”

Microorganisms are distributed everywhere even in extreme environments such as caves. The underground surfaces are minerals rich and the life in there is found to be related to both biotic and abiotic factors. Because the cycle of these minerals is insured by the chemolithotrophs living in there. In addition, caves are considered to be important reservoirs of bioactive compounds. However, caves are entered for different reasons. Some of the cavers are of scientific research, some of them are for recreational reasons like sports and simple cave visits. All these activities are thought to impacts the visible mat and invisible colonies of microorganisms through mechanical force or importing exogenous microorganisms. This study summarizes the different impacts which can be caused by the different human activities in caves. Finally, perspectives of the conservation of the cave microbial structure are suggested for the further uses of caves.

“…Jone et al investigated the metabolic potential and ecological role of snottite Acidithiobacillus using metagenomics sequencing, and revealed that the population was autotrophic, and oxidizing sulfur via the sulfide-quinone reductase and sox pathways, indicating Acidithiobacillus was the snottite architect and main primary producer (Jones et al, 2012). Moreover, Acidithiobacillus thiooxidans obtained from the Frasassi cave snottites was also reported to carry a high potential to remove arsenic from contaminated sediments (Beolchini et al, 2017). Microbial activity is also crucial for cave sulfide oxidation below the water table; the springs and discharge streams in SAS caves are colonized by thick, filamentous microbial mats (Engel et al, 2004b).…”

Among fundamental research questions in subterranean biology, the role of subterranean microbiomes playing in key elements cycling is a top-priority one. Karst caves are widely distributed subsurface ecosystems, and cave microbes get more and more attention as they could drive cave evolution and biogeochemical cycling. Research have demonstrated the existence of diverse microbes and their participance in biogeochemical cycling of elements in cave environments. However, there are still gaps in how these microbes sustain in caves with limited nutrients and interact with cave environment. Cultivation of novel cave bacteria with certain functions is still a challenging assignment. This review summarized the role of microbes in cave evolution and mineral deposition, and intended to inspire further exploration of microbial performances on C/N/S biogeocycles.
