In the microbial world, one of the most interesting fields to study is extremophilic
microorganisms. These microorganisms live in very particular conditions that are hostile to the
majority of microorganisms, but extremophiles are adapted to these conditions and develop
stable and active communities. These extreme environments can be of many types, including
extreme variations in pH and temperature, high pressures at the ocean floor, or high salinity in
endorheic environments. The latter is the case presented in this work. The objective is to carry out a literature review
within the current scientific literature on the adaptations and modifications of microorganisms
found in hypersaline endorheic environments, which are bodies of water in landlocked basins
with very high salt concentrations. These hypersaline endorheic environments provide a very
interesting, unique, dynamic, and nuanced ecosystem where entire communities from the three
domains of life, namely Archaea, Bacteria, and Eukarya, thrive. This work presents information about the adaptations and modifications exhibited by halophilic microorganisms (which require a certain amount of salts in their environment to survive) and halotolerant microorganisms (which do not require salts in their environment but can tolerate their presence). The aim is to provide a comprehensive understanding of how microorganisms
are capable of surviving and proliferating in such extreme environments. This work encompasses
interdisciplinary aspects from different fields of science, such as biology, microbiology, and,
particularly, with a stronger emphasis in this study, biotechnology.
Adaptations to saline environments are highly diverse, ranging from strategies based on osmotic
balance between solutes in the environment and intracellular solutes to prevent cell
dehydration, to structural modifications at the membrane and proteome levels.
Within the modifications and adaptations to hypersaline environments, there are the
production of highly interesting biomolecules for the pharmaceutical and biomedical industries,
offering unique opportunities to explore and delve into the commercial potential of these
microorganisms. Additionally, this work will allow us to visualize how these environments are affected by current
climate emergency conditions, which must be reversed as they can lead us to irreversible and
dire situations 15 |
