AVF1 virus resistant to high temperature and strong acid environments has been found in hot springs in Yellowstone, USA.

An international team of researchers recently discovered that AVF1, a virus found in yellowstone hot springs in the United States, has a special outer membrane that makes it resistant to high temperatures and strong acids.
this unprecedented membrane construction may provide inspiration for the design of new materials that are super tough.
the virus is called AVF1, which can infect the hot springs of the haptic acidophilus bacteria, the latter is a love of acidic environment of the ancient bacteria.
AVF1 has an ultra-strong protective outer membrane that makes it resistant to hot spring environments with water temperatures of more than 80 degrees Celsius and highly acidic, but the specific structure of the film was not previously known.
Scientists at the University of Virginia, the Pasteur Institute in France and other institutions reported in the American biomedical journal Electronic Life that they combined electron microscope analysis and computer modeling to find that the outer membrane of the AVF1 virus is about 2 nanometers thick and consists of lipid molecules.
these molecules bend into horseshoe shapes, making the membrane highly stable, a structure that has never been found in nature before.
in most organisms, the various membranes inside the cells are usually double lipid membranes, while the membranes of ancient bacteria are single layers, like double-layered membranes fused together.
analysis by scientists found that the membrane of the AVF1 virus is also single-layered, the raw material comes from the membrane of the host cell, but the structure is different.
that is, the virus steals some flexible lipid molecules from the host and bends them into horseshoe shapes to form their own new membranes.
scientists involved in the study say the tectonic scheme has great potential for applications, such as the manufacture of strong nanomedical "packaging materials" that can be used to carry drug molecules to designated parts of the patient's body and then release them without breaking before they reach their destination, or they could be used to design new building materials that can withstand strong earthquakes.
