Description
Technical field
This utility model belongs to Protein Detection field, particularly to a kind of dress of quick mensure microorganism outer membrane protein state
Put and method.
Background technology
Soil microorganism is the engine of driving element biogeochemical cycle, and the oxidation-reduction process that it drives is contact
Different ring layer materials and the important tie of energy exchange.
1987, American scientist derek lovely first from deposit separate obtain one plant can utilize extracellular
Solid matter is that the microbicidal metal of electron acceptor reduces ground bacillus gs-15 (geobacter metallireducens gs-
15).1988, American scientist ken nealson separation from the deposit in New York oneida lake obtains another strain to be had
The microorganism Xi Washi Oneida mr-1 (shewanella oneidensis mr-1) of same capabilities.This two plants of microorganisms
Find, open the frontier of extracellular breathing.
Extracellular breathing refers under anaerobic condition, and microorganism discharges electronics, the electronics of generation in intracellular exhaustive oxidation Organic substance
It is delivered to extracellular electron acceptor through intracellular respiratory chain, and produce the process that energy maintains own growth.Extracellular microbial external respiration machine
System needs to probe into from protein level.Cytochrome c (c-type in extracellular electron transfer process, on microbial cell film
Cytochromes, c-cyts) it is most important active specy, electronics passes through the phase interaction on cell membrane between cytochrome c
With being transferred to epicyte from inside microbes, thus completing whole redox reaction.In view of about extracellular microbial external respiration
The oxidoreduction of soil Minerals, and mutually can be coupled with the degraded of the Transport And Transformation of heavy metal and organic pollution,
Have great importance in biogeochemical process, the research of cytochrome c becomes very crucial.
In extracellular respiratory, the transmission of electronics is substantially the oxidoreduction between each material, however, active somatic cell pigment c
Redox state be not easy to measure.Conventional molecular biology method, such as rna expression analysis, transcriptome analysis etc.,
The total amount change of cytochrome c all can only be obtained.In view of containing a large amount of heme group in cytochrome c, this group 410~
419 nanometers, 522 nanometers and 550 nanometers have and absorb more by force, can come test cell pigment c's using these absworption peaks
State change.Therefore, cytochrome c is carried out extraction purification by researcher, is characterized in conjunction with its spectral absorption, for extracellular electricity
The research of sub- pass through mechanism.
However, the cytochrome c on cytochrome c after extraction purification and living microorganism adventitia differ greatly it is difficult to
The time of day of reflection microbial function albumen.Test living microorganism cytochrome c, is truly to reflect microbial function albumen
The key of state.But live bacteria is bulky grain, in the solution formed suspension, incident illumination occurs after suspension scatter and
Change direction so that most of transmitted light cannot be introduced into detector it is difficult to the actual transmission light quantity of detection, bring very high background
Absorption errors, common spectrum test cannot be smoothed out.Integrating sphere is that one kind to being in ball or can be placed on outside ball and close
Sample at certain window to scattering of light or a kind of high efficiency device of being collected of transmitting, in recent years, using ultraviolet-can
See that spectrum is connected with integrating sphere it is achieved that capture to scattered light, smoothly deduction scattered light background value, reduces baseline noise,
Scattered light background absorption is solved the problems, such as from methodology, active somatic cell pigment c test is applied.Built purple using integrating sphere
Outward-visible diffuse transmission light spectra system carries out spectrum test to suspension system, and nakamura etc. is obtained using spectrum means first
The redox state change of Shewanella cytochrome c.
However, ultraviolet-visible spectrophotometer carries out during broadband spectrum test being swept it is necessary to constantly adjust wavelength
Retouch, scanning process then needs time enough., scanning speed sets taking the general tu-1901 type spectrophotometer of the general analysis in Beijing as a example
It is set to " fast ", sweep spacing is " 1 nanometer ", from 600 nano scannings to 300 nanometers, takes around 70 seconds.And the micro- life of extracellular breathing
The change of beyond the region of objective existence theca cell pigment c state belongs to a second order reaction.Obviously overflow using the traditional slow that common spectrophotometer is built
Transmitted light spectrometer cannot realize the real-time monitoring of microorganism adventitial cell pigment c state change.On the market, fiber spectrometer can
Rapid data record is carried out to the whole spectrum of 200-1100nm, but although fiber spectrometer has rapid data record
Function, but there is no and the integrating sphere equipment being applied to suspension test associated with fiber spectrometer, ordinary optic fibre spectrogrph is to suspension
When system is tested, it will have very high baseline noise so that test cannot be carried out.
