Michere TV tizilombo tosaoneka ndi maso

mabakiteriya Research amafuna ntchito mosamala ndi zida zambiri ndi zida. The tizilombo zasayansi mwamsanga anachulukana anali akasamuka ntchito bwinobwino, ntchito yapadera michere sing'anga. Kapangidwe awo ndi zinthu biophysical oyenera kukula yogwira chikhalidwe bakiteriya.

Michere TV. Microbiology ndi ntchito zina

Chambiri mabakiteriya mu m'galasi mwakula pa Petri mbale amene anadzazidwa ndi zakudya kapena theka-zamadzimadzi nkhani. Izi ndi sing'anga michere, kapangidwe ndi katundu pafupi n'zotheka kukula chilengedwe cha chikhalidwe cha khalidwe.

Ikani TV ngati kafukufuku microbiological ndi Laboratories mankhwala matenda. Recent akugwira ntchito makamaka ndi dabs wa tizilombo toyambitsa matenda kapena osiyanasiyana, malo mwadongosolo mwachindunji anatsimikiza mtima m'banja.

Natural ndi kupanga media

Ulamuliro yaikulu ya ntchito ndi mabakiteriya - kusankha bwino a sing'anga. Izo ziyenera kukhala oyenera i ambiri mwa amene zili micro- ndi macroelements, michere, pH zonse, kuthamanga osmotic, ndipo ngakhale kuchuluka kwa mpweya mu mlengalenga.

media michere anawagawira m'magulu awiri akuluakulu:

1. Chilengedwe. zosakaniza oterowo anakonza kuchokera zosakaniza achilengedwe. Izi zikhoza kukhala madzi, mbali zomera, manyowa, masamba, zomera ndi nyama minofu, yisiti ndi zina zotero. D. Izi yodziwika ndi okhutira mkulu wa mankhwala zobwezedwa zachilengedwe chimalimbikitsa patsogolo chikhalidwe cha mabakiteriya. Ngakhale ubwino zoonekeratu, chilengedwe salola kuchititsa maphunziro apadera ndi tizilombo ta enieni mabakiteriya.
2. Kupanga TV. Iwo amasiyana mipweya awo amadziwika anapangira enieni a zigawo zikuluzikulu zonse. media oterowo Konzekerani makamaka chikhalidwe bakiteriya, mmene kagayidwe amadziwika pasadakhale kafukufuku. Ndipotu, pachifukwa ichi n'zotheka kukonzekera chotero sing'anga kupanga kukula tating'onoting'ono. Iwo ntchito kwa kusanthula moyo bakiteriya. Mwachitsanzo, mungapeze zimene zinthu iwo kumasula mu chilengedwe ndi mochuluka bwanji. Tizilombo m'malo achilengedwe nawonso kukula, koma mungawononge kusintha kulikonse kachulukidwe mu zikuchokera sangakhale chifukwa umbuli wa kufanana choyambirira cha mankhwala.

Masiyanidwe chilengedwe matenda

osati alipidwa TV michere angagwiritsidwe ntchito pa ntchito ndi mabakiteriya. Microbiology - sayansi lalikulu, ndipo chotero mu kafukufuku ndi zina zofunika kuti kusankha tizilombo pa malo ena aliwonse. Ntchito atolankhani masiyanidwe-matenda zasayansi limachititsa kusankha madera anakhumba mabakiteriya pa mbale petri ya maziko amuzolengedwa la umoyo wawo.

The zikuchokera TV ngati wakhala zikuphatikizapo zigawo izi:

1. Zakudya kukula selo.

2. kusanthula gawo lapansi (chinthu).

3. chizindikiritso, amene adzakupatsani mtundu chosiyana pa zina otaya anachita.

Chitsanzo ndi masiyanidwe-matenda TV thanzi "Endo". Izo ntchito posankha chambiri tizilombo kuti akhoza kuswa pansi lactose. Poyamba, chilengedwe ali ndi mtundu pinkish. Ngati njuchi tizilombo sangathe kuphwanyaphwanya lactose, zimatengera mwachizolowezi woyera. Ngati mabakiteriya angathe adzaphatikizana gawo lapansi, iwo utoto mu chosiyana zofiira.

chilengedwe kusankidwa

The Laboratories matenda zambiri akugwira ntchito ndi zikwapu, muli mitundu yosiyanasiyana ya mabakiteriya. Mwachionekere, kuti khalidwe la ntchito ayenera kukhala ndi njira kusankha zofunika njuchi zambirimbiri a alendo. Apa angathandize kuswana pansi tizilombo, zikuchokera amene mwangwiro chikufanana moyo wa mtundu umodzi wokha wa tizilombo.

Mwachitsanzo, ngati abwino kusankha locheperapo kwa kubalana wa Escherichia coli. Ndiye, kuchokera chodzala zosiyanasiyana mabakiteriya pa mbale petri, tikuona njuchi okha lomwelo E. coli ndi kenanso. Musanayambe ntchito, muyenera kudziwa bwino za kagayidwe mabakiteriya kuphunzira bwinobwino kusankha iyo kuchokera chisakanizo cha mitundu ina.

Olimba, theka-olimba ndi madzi TV chikhalidwe

mabakiteriya akhoza kukhala wamkulu osati pa magawo olimba. TV chikhalidwe amasiyana boma la loitanirana, malingana zikuchokera kupanga lapansi. Poyamba, iwo onse ndi kugwirizana madzi, ndi kuwonjezera Hagara kapena gelatin mu kuchuluka ena a congeals kusakaniza.

Madzi TV michere zambiri zopezeka mu machubu. Ngati pali kufunika kukula mabakiteriya wotere, njira ya nyemba chikhalidwe ndi kudikira kwa masiku 2-3. The chifukwa angakhale osiyana: precipitate ndi aumbike, filimu, zikuoneka tiwolokere kapena flakes yaing'ono anapanga njira mitambo.

Olimba sing'anga kawirikawiri amagwiritsidwa ntchito kafukufuku microbiological kuphunzira katundu mabakiteriya ankawalamulira. media amenewa nthawi zonse chimaonekera kapena translucent, kuti athe mukazindikira mtundu ndi mawonekedwe a chikhalidwe cha tizilombo.

Kukonzekera TV chikhalidwe

Zapamwamba kukonzekera magawo monga osakaniza nyama ofotokoza mu msuzi, gelatin kapena Hagara. Ngati mukufuna kupanga olimba kapena theka-zamadzimadzi gawo lapansi mu madzi anawonjezera ankalemekeza 2-3% ndipo 0.2-0.3% ya gelatin kapena Hagara. Iwo zimapezeka mu osakaniza oipa, koma ndithudi si gwero la zakudya. Choncho, sing'anga michere zakonzedwa ndi kuti ali oyenera kukula chikhalidwe bakiteriya.
