Utilize genetic engineering to foster the new microorganism and succeed
It is reported through the ingenious genetic manipulation behavior, the researchers of the research institute of American Craig Venter transplant a bacterium's genome to yeast, transplant it to a hollow bacterium shell after transformation, thus has produced a new microorganism. This technology, in order to offer a kind of simple and more easy route the genetic transformation to the organism seldom studied in the laboratory, there is important value on fostering the microorganism producing the fuel or removing poisonous chemicals.

Benefit from, study for many years to yeast and Escherichia coli microorganism, scientist already can pay complicated genetic transformation with genetic tool these, make out executable more complicated task or microorganism producing the material more effectively such as changing the whole chemical route. However, the microorganism that a lot of industry pays close attention to, the microorganism substantially as producing such unique ability of chemicals in those is not easy to make. The scientists hope to design the picture to only shut the goal organic matter such as microorganisms, by only changing into the fuel more effectively.

Through inserting the genome of these bacteria in yeast, the scientific research personnel of Venter research institute find, they control him more easily. Researchers say, what people wanted is the ability of yeast or Escherichia coli, but not there are organs of its photosynthesis. It will be an extremely interesting thing to combine these two kinds of genome in the living beings fuel world.

The lofty tone of Venter research institute seeks to establish the life from scratch, various technology are emerging from it constantly too, they want to establish one and formate the gene, then control or restart a receptor cell with it. In 2007, this research institute published the thesis to describe their genome transplants the research results, the genome is transplanted to transfer the genome of bacterium of a kind of type to a closely related bacterium, thus make hosts have the donor's characteristics. Last year, researchers mixed together with establishing one out and formated genome through sewing formating the bit of DNA.

Formating organism in order to make one out, researchers have to formate the genome to transplant into a cell, make it succeed in restarting cells. Formating the genome is fitted into yeast, mean it lacks the biological mark characteristics of some bacteria. Researchers find, without these marks, host's bacterium will regard transplanting genome as the outside invador and destroy him.

A new technology issued newly on the network edition of Science makes this question easily solved. Researchers move the mycoplasma genome of silk to plant into yeast for the first time. Though the scientists have sprouted bacterium's bit of DNA in yeast, this sprouts the intact genome of bacterium by this way for the first time. Using the existing yeast genetic engineering tool, researchers have changed the hereditary material of the bacterium chemically, thus make it carry molecule mark characteristic of the bacterium. Researcher modify genome, move, plant the intersection of goat and mould the intersection of thick liquid and fungus into this piece ' Have very near blood reason relations with the mycoplasma of silk) In order to produce a silk mycoplasma cell.

American Boston University biological engineer Jim and Collins says, this research has strengthened the ability of the genome project and opened up the new application. To biological energy and biomaterial industry, this is a great progress.

At present, researcher devoted to, go on, test to other bacterium in order to transfer production technology to with biological fuel industry at the more relevant organic matter. Researchers say, the hereditary route of the organic matter can decompose the environmental pollutant, it move, plant into behind the bacterium through genetic engineering, can survive like acid pond and abominable and among the environments polluted, then clear up on can be used for these areasing.
