Report on Biology We all know that first life forms appeared in water. Water is the cradle of nature. Millions years ago first Amphibians stepped on the ground and started to conquer new living space. The result we can see all around us. Many people say that few thousands years ago our planet was full of life and promises. Nowadays humanity in its thirst for development turns the Earth into a desert of concrete and stone.
The more we build, the more we destroy. We dont value the air we breathe, the water we drink. The natural water basins are in disastrous state. Annually tones of oil are spilled into the oceans causing a great damage.
On other hand some people understand the seriousness of problem and try to save marine life. The Institute for Genomic Research (TIGR) is a not-for-profit research institute based in Rockville, Maryland. TIGR, which sequenced the first complete genome of a free-living organism in 1995, has been at the forefront of the genomic revolution since the institute was founded in 1992. TIGR conducts research involving the structural, functional, and comparative analysis of genomes and gene products in viruses, bacteria, archaea, and eukaryotes (Science Daily) According to the article in Science Daily their recent researches are about the genetic makeup of a marine microbe have given scientists a new perspective on how bacteria make a living in the ocean a view that may prove useful in wider studies of marine ecology. (Science Daily) That is why I chose this article, because such researches have a great value for our future. Now I will try to prove to you my point of view.
Scientist at the University of Georgia's Department of Marine Sciences and at The Institute for Genomic Research (TIGR), along with several collaborator found out that that S. pomeroy i has the genetic tools to enable it to use inorganic compounds (such as inorganic sulfur) for energy, which allows the microbes to use organic carbon more efficiently in low-nutrient ocean environments (Science Daily). Silicibacter pomeroy i is a member of an important group of marine bacteria. After deciphering and analyzing the DNA sequence of S. pomeroy i was found that this microbe can specialize in a ways that allow it to love in hot spots microscopic areas of the ocean that are rich in organic matter, typically related to living and dead microbial cells (Science Daily). This discovery has a really great importance because it will not help not only to generate the hypotheses about how the ocean works but also will help to investigate these hypotheses in the ocean.
On other hand science can use the S. pomeroyi's ability for numerous adaptation especially adaptation for existing in so called hot spots. Moran says the S. pomeroy i sequence "demonstrates that genomes of ecologically relevant cultured microbes have enormous potential to move marine biogeochemical research forward at a rapid pace. (Science Daily) This discovery can be used for the improvement of ocean ecosystem, which in turns leads to the improvement of nature environment. The ability of S. pomeroy i microbe for litho heterotrophy is simply amazing.
According to the Science Daily "litho heterotrophy" is the ability of marine bacteria that typically rely on organic carbon fixed by primary producers as their source of cell material to also use inorganic compounds (in this case, carbon monoxide and sulfur) for energy. Can you imagine that such a tiny microbe can save more of the organic compounds for biosynthetic processes simply by allowing more efficient use of organic carbon in an environment that has little to go around. Scientists hope that this bacterium can save the ocean. Bibliography Microbe's Genome Reveals Insights Into Ocean Ecology, Science daily, December 29, 2004
