A new bacterial species from a hydrothermal vent throws light on microbial evolution https://phys.org/news/2023-11-bacterial-species-hydrothermal-vent-microbial.html paper: https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.006132
"The #discovery of a #mesophilic (adapted to moderate temperatures) #Hydrogenimonas species was unexpected. The strain likely provides us with the opportunity to investigate their evolutionary transition from a #thermophilic to a mesophilic and from an #autotrophic (capable of creating organic compounds) to a #heterotrophic (consumes #autotrophs) lifestyle"
Deep-sea hydrothermal vents are hot springs on the ocean floor. Sea water penetrates into the ocean crust, becomes heated, and rises to the seafloor surface carrying dissolved nutrients. Around these vents, far from any sunlight, vibrant biological communities are found. Here, microbes play the role of primary producers through chemosynthesis—similar to the role that plants play on land through photosynthesis.
