Nutrient nhau zvidukuduku

Research utachiona zvinoda akangwarira basa pamwe vakawanda zvokushandisa uye zvokushandisa. The tusingaoneki murabhoritari sezvo nokukurumidza zvawanda uye vakakwanisa kuramba zvakajairika basa, vachishandisa chaiyo inotonhorera svikiro. Chimiro chavo uye biophysical ezvinhu akakodzera kuti kushingaira ikure kwemabhakitiriya tsika.

Nutrient vezvenhau. Zvidukuduku uye mamwe mafomu

Mapoka utachiona ezvokunambira kunze kwomuviri waamai vari akura musi Petri midziyo kuti vakazadzwa ine mondo kana Semi-mvura mukati. Ndicho inotonhorera svikiro, murwiyo uye zvivako sezvo pedyo sezvinobvira yepanyama ikure tsika nokuti unhu.

Shandisa nhau dzakadaro microbiological tsvakurudzo uye zvokurapa chirwere mumarabhoritari. Recent vari kushanda kunyanya ne dabs pamusoro pathogenic kana mikana utachiona, hurongwa nzvimbo akatsunga zvakananga tsika.

Natural uye chakaita zvokugadzirwa vezvenhau

Nokutonga inokosha yokushanda pamwe mabhakitiriya - ndizvo zvakarurama kusarudza svikiro. Zvinofanira kuva akakodzera vakawanda nzira, ramakagadzwa zviri micro- uye macroelements, makemikari, kugara ph, osmotic kumanikidzwa, uye kunyange chikamu neoxygen iri mumhepo.

Nutrient vezvenhau dzinoiswa muzvikwata zvikuru zviviri:

1. Yepanyama zvakatipoteredza. wemisanganiswa vakadaro kugadzirira kubva dzinongoitika ingredients. Izvi zvingava rwizi mvura, chirimwa zvikamu, mupfudze, muriwo, chirimwa uye mhuka rinenge mbiriso, uye zvichingodaro. D. aya dzinoratidzwa mukuru zviri dzinongoitika makemikari siyana iyo inosimudzira kukura kwemabhakitiriya tsika. Pasinei izvi zvakwakanakira pachena, yepanyama mhoteredzo haabvumiri kuitisa unyanzvi hwakasiyana vanodzidza dzakananga okuva mabhakitiriya.
2. Chakaita zvokugadzirwa vezvenhau. Ivo zvisingapindirani dzavo makemikari anoumba anozikamwa chaiwo kukura vose zvinoriumba. Vezvenhau vakadaro vakagadzirira imwe kwemabhakitiriya tsika, sezvamakaropafadzwa muviri anozivikanwa pachine mutsvakurudzi. Kutaura zvazviri, nemhaka iyi zvinokwanisika kugadzirira chakaita zvokugadzirwa svikiro saizvozvo microbial kukura. Vari akashandiswa Kuongororwa kwemabhakitiriya upenyu. Somuenzaniso, unogona kuwana chii zvinhu zvavakanga kusunungura mumba zvakatipoteredza uye sei. Tusingaoneki dzinongoitika runyararo kunowedzerawo, asi arambe chero quantitative kuchinja murwiyo havagoni kuva nokuda kusaziva chepakuvamba kukura nezvinhu.

Differential chirwere zvakatipoteredza

kwete chete zvatinosiita inotonhorera vezvenhau zvinogona kushandiswa pabasa pamwe utachiona. Zvidukuduku - imwe sainzi guru, uye saka ari tsvakurudzo dzimwe nguva zvakakodzera kuti kusarudzwa zvigare pamusoro chero chikonzero. Kushandiswa differential-chirwere vezvenhau murabhoritari runoita kusarudza zvinodiwa mapoka utachiona pamusoro Petri nezvokudya nokukanganisika hwaro zvokurarama nazvo zvavo.

The Zvinoumba nhau dzakadaro hwagara zvinosanganisira zvinotevera zvinoriumba:

1. zvinovaka muviri kuti sero kukura.

2. vakaongorora substrate (fuma).

3. chakarurama, anozopa munhu nevamwe ruvara pane imwe chokubuda maitiro.

Muenzaniso uri differential-chirwere vezvenhau zvinovaka muviri "Endo". Rinoshandiswa kuti kusarudza mapoka mabhakitiriya anogona kuputsa lactose. Pakutanga, zvakatipoteredza ichi ane pinkish ruvara. Kana nyuchi zvigare haisi kukwanisa kuputsa lactose, zvinotora senguva chena. Kana mabhakitiriya anogona munamatire kuti substrate, vari kupendwa mune zvakasiyana ruvara rwakati piriviri kutsvuka.

zvokuwedzera zvakatipoteredza

The chirwere mumarabhoritari kazhinji vari kushanda shamhu, rine mhando dzakawanda akasiyana mabhakitiriya. Zviri pachena, nokuti unhu basa anofanira kuva nzira kusarudza zvinodiwa muhutongi vakawanda vatorwa. Pano anogona kubatsira maberekero pasi nokuda utachiona, murwiyo iyo anonyatsorayiridzwa vachiwirirana upenyu chimwe chete mhando zvigare.

Somuenzaniso, zvakadai akakodzera kusarudzwa svikiro chete kuti kubereka vana Escherichia coli coli. Zvadaro, kudyara akasiyana-siyana utachiona pamusoro Petri mundiro, tinoona chete nyuchi iroro E. coli uye ndikasazovapo. Usati watanga kushanda, unofanira kuva nezivo zvakanaka muviri kwemabhakitiriya vakadzidza kuti abudirire sarudza kubva musanganiswa dzimwe mhuka.

Solid, Semi-zvikukutu uye mvura tsika nevezvenhau

Mabhakitiriya anogona kukura kwete chete pane zvakasimba substrates. tsika nevezvenhau zvisingapindirani rehurumende aggregation, zvichienderana Kuronga gadzira. Pakutanga, vose vane mvura kusachinja-chinja, uye kuwedzera Hagari kana gelatin mune imwe chikamu musanganiswa congeals.

Liquid inotonhorera vezvenhau zvinowanzowanika mune sepombi. Kana pane vanoda kukura kwemabhakitiriya mumamiriro ezvinhu akadaro, mhinduro ane tsika yokuenzanisira uye kumirira mazuva 2-3. Zvingaguma zvakasiyana: a precipitate aumbwa, firimu sokuti kuyangarara kana flakes duku vakaumba ramakore mhinduro.

svikiro Solid rinowanzoshandiswa microbiological tsvakurudzo kudzidza ehupfumi utachiona nyuchi. Vezvenhau akadaro nguva dzose yakajeka kana translucent, kuti kukwanisa nemazvo kuziva ruvara uye chimiro tsika tusingaoneki.

Preparation tsika nevezvenhau

Very kungotaura kugadzirira substrates akadai nyama-inobva musanganiswa kupinda muto, gelatin kana Hagari. Kana uchida kuti yakasimba kana Semi-mura substrate kupinda mvura iri awedzera azvaitwa 2-3% uye 0.2-0.3% kubva gelatin Hagari kana. Ivo basa guru iri nokuomesa nezvakavhenganiswa, asi zvirokwazvo havasi tsime muviri. Nokudaro, inotonhorera svikiro rinogadzirirwa uye kuti vari akakodzera ikure kwemabhakitiriya tsika.
