Domain Bacteria Extreme Environments

Eukaryotes are the most flexible with regard to forming cooperative colonies such as in multi cellular.

Domain bacteria extreme environments. Dating back to more than 40 million years ago extremophiles have continued to thrive in the most extreme conditions naming them one of the most abundant lifeforms. Different in rna polymerases and thus in their protein synthesis. Archaea often live in extreme environments and include methanogens extreme halophiles and hyperthermophiles. Many archaea live in extreme environments such as hot springs and deep sea hydrothermal vents and are called extremophiles as a result.

One reason for this is that the ether containing linkages in the archaea membranes is more stabile than the ester containing linkages in the bacteria and eukarya and are better able to withstand higher temperatures and stronger acid concentrations. Because of their originality abundance and the many interactions and symbioses that govern the dynamics of bacterial and archaean communities in extreme environments these microbes represent a largely unexplored genetic resource figure 7. This includes adapting to use a wide variety of food sources. They can survive and even thrive under some of the most difficult conditions on planet earth like very hot extremely acidic or very alkaline environments.

The bacteria are also prokaryotic. Archaeans are extreme organisms. Archaeans tend to adapt quickly to extreme environments such as high temperatures high acids high sulfur etc. Archaea often live in extreme environments and include methanogens extreme halophiles and hyperthermophiles.

Cocci round bacilli rod shaped and irregular are some examples. Their domain consists of cells with bacterial rrna no. These organisms are dominants in the evolutionary history of the planet. This is not the same as a more anthropocentric and non.

Bacteria are single celled primitive organisms that form a domain of organisms diverse in shape size structure and even habitats. The cells belonging to the domain archaea are single cell organisms like bacteria but they share characteristics with eukarya cells found in plants and animals. Thrives in extreme environments eating hydrogen gas carbon dioxide and sulfur. An extremophile is an organism with optimal growth in environmental conditions considered extreme in that it is challenging for a carbon based life form such as all life on earth to survive.

Most archaea are extremophiles and are found in extreme environments like the deep sea mountains hot springs salt brine etc. Thus the search for new biocatalysts and antibiotics based on the microbial biodiversity of extreme environments is a rapidly expanding discipline. Ancient bacterias that are often found in extreme environments such as those that have affinity towards salt or heat. One reason for this is that the ether containing linkages in the archaea membranes is more stabile than the ester containing linkages in the bacteria and eukarya and are better able to withstand higher temperatures and stronger acid concentrations.
