A detailed description of extreme microorganisms

Extreme microorganisms are the general name for those most suitable for living in extreme environments, including heat, cold, acid, alkali, pressure, gold, radiation, drying and extreme anaerobicWhat is the use of1 and extreme microorganisms?to carry out research on extreme microorganisms is of great scientific significance for revealing the mystery of the origin of the biosphere, clarifying the mechanism of biodiversity formation, understanding the limits of life and the laws of its interaction with the environmentThe adaptation mechanism found in extreme microorganisms will also be the theoretical basis for humans to search for extraterrestrial life in spaceThe results of extreme microbial research will greatly facilitate the use of microorganisms in the fields of environmental protection, human health and biotechnology"text-align: "content",""img src""alt""details of extreme microorganisms" title",2, radiation-resistant abnormal cyococcalsradiation-resistant coccid bacteria (Deinocous radioccdurans) have ultra-strong radiation, oxidation, high temperature, drought and other resistance, known as "the world's most tenacious bacteria" In 1999, U.Sscientists completed genome-wide sequencing of the bacteria and published it in the journal ScienceIn-depth study of the anti-retrogenesis of radiation-resistant abnormal cocci bacteria plays an important role in understanding the mechanism of the bacteria's adaptation and stress reaction in extreme environmentsLi Jie and others to beta-semi-lactose sideloin as the report gene for the reporting gene to build a radiation-resistant abnormal cyococcal promoter detection systemUsing the radiation-resistant abnormal cyococcal genome as a template to amplify the promoter fragments of the important anti-reverse gene of radiation-resistant abnormal cyococcal bacteria, connect them to the Ecoli-radiation-resistant cocci shuttle carrier pRADZ1, construct a recombinant granules with promoter activity detection function pRADZ-PgroE, pRADZ-PrelA and pRADZ-PrelAndine, and convert them to radiation-resistant coopateThe results showed that these promoters were able to initiate the expression of Lac-Z reporting genes in radiation-resistant colicoccals and were subjected to induced regulation by stress conditionsThe construction of the activity detection method of radiation-resistant abnormal cyococcal initiators provides an important experimental basis for the study of the strain-specific stress response systemLearn more about extreme microbes, you can view the original text or continue to focus on microbial technology
