What is the structure of a Thermoacidophile?

Do thermoacidophiles reproduce?

They don't, in a literal sense.

A thermoacidophile, according to the website of University of California at Davis School of Medicine is a microbe that prefers to live in a mildly acidic environment with a pH between 4 and 5. (1)

Thermoacidophiles must have been around when life first began, as they live on the crust of the earth where there is plenty of heat, but only small amounts of oxygen and carbon dioxide (CO2). Thermoacidophiles reproduce by splitting apart their cell walls into millions of smaller individual cells. Then they reassemble, creating tiny versions of the bigger organism. All organisms must, therefore, be able to split themselves into smaller and smaller pieces.

The cells that make up the organisms of thermophiles and thermocarbophiles have pores that are much too small to allow the large molecules necessary for reproduction inside the cell. This prevents reproduction in thermophiles and thermocarbophiles. The organisms do, however, reproduce successfully at temperatures up to 100 degrees Celsius.

Why is reproduction required? Because if an organism lacks the ability to reproduce it will die out. If the population of an organism is completely destroyed, that means that only one or a very few copies of the species are left. This means that only one or a very few copies of the species survive.

The organisms in our body reproduce to create new bodies and to pass their DNA into the next generation. If they did not reproduce, all of our DNA would become extinct, as we know it today. There could be no more us.

Where can you find thermoacidophiles? In the ocean, where the water has a slightly acidic pH and some CO2 dissolved in the water. Thermophiles prefer high temperatures and low oxygen levels, and may be found in hot springs, deep oceans, deep lakes, volcanic vents, caves, and sulfur fields. A list of locations where you can find thermoacidophiles has been compiled by the University of Maryland (2).

A recent study suggests that bacteria which live on the ocean floor also contribute to global warming, as they break down organic material to release the heat that radiates back into space (3). How do you think that thermophiles and thermocarbolophiles are related?

What are the features of thermoacidophiles?

===========================================.

Thermoacidophiles are a group of microorganisms that grow optimally in hot acidic conditions. These conditions can be achieved when fermenting low-pH hydrolyzates, brewing acidic wort or brewing wort with reduced hop acidity or low pH, or adding acid to malted barley. They are found as obligate psychrophiles in the deep subsurface (> 40 C), as mesophiles in soil or sea water, and as moderate to obligate psychrophiles in surface waters. In this review we focus on recent progress in studies on thermophiles and acidophiles in general, which resulted in novel insights into the molecular features, metabolic networks and functions of these organisms. We begin with a brief introduction to these two groups of microorganisms, followed by more specific chapters about each of them.

Introduction. Bacteria are the most abundant organisms on earth, and their diversity is enormous. Bacterial cells can vary in shape, size, and life style, but they have some common features: 1) Bacterial cells have an envelope. The outer membrane can be composed of proteins, lipids, or polysaccharides, and it is permeable to water and small ions, but impermeable to large solutes. The envelope is the first line of defense against toxic chemicals and other environmental assaults. 2) Bacterial cells contain a nucleus. The DNA is coiled around histone proteins and organized into chromatin. 3) Bacterial cells are enclosed in a cell wall, an extremely tough, porous structure composed of peptidoglycan. 4) Bacterial cells grow using a metabolic energy supply, which originates from either glycolysis (proteobacteria and some clostridia) or the tricarboxylic acid cycle (most others). Many bacteria are facultative anaerobes, that is, they will grow under both aerobic and anaerobic conditions.

Do archaea contain flagella?

Most Archaea (for example, Sulfolobus shibataii and Pyrococcus furiosus) use two-subunit filaments to perform motility (that is, they use them for locomotion, not orientation), but in contrast to eukaryotes, Archaea do not possess flagella. However, some Archaea also use a single subunit to propel themselves through the water by rotating rapidly: The presence of FliF orthologs in Archaea indicates that their chemotactic receptors could be used to respond to externally supplied ligands. It is therefore tempting to speculate that these archaea use single subunit proteins as flagella.

And it was actually my suspicion going in: That such ancient organisms likely had to have had flagella until bacteria gained a better energy source (I was thinking ATP hydrolysis of some sort rather than the much slower rotational propulsion). So, we can conclude that all archaeal species (I think?) don't use flagella to sense external gradients to direct their motility. However, there is one archaean species that does use flagella (and in a different way than eukaryotes).
