Gutondekanya ibyokurya bya Petri --—
1. Ukurikije uburyo butandukanye bwo gukoresha ibiryo byumuco, birashobora kugabanywamo ibyokurya byumuco utugari hamwe nibiryo byumuco wa bagiteri.
2. Irashobora kugabanywamo amasahani ya petri ya plastike hamwe nibirahuri bya petri ukurikije ibikoresho bitandukanye byo gukora, ariko ibyinshi mu byokurya bya petri bitumizwa mu mahanga hamwe n’ibiryo bya petri bikoreshwa ni ibikoresho bya pulasitiki.
3. Ukurikije ubunini butandukanye, birashobora kugabanywa muri 35mm, 60mm na 90mm z'umurambararo.150mm ibiryo bya Petri.
4. Ukurikije itandukaniro ryo gutandukana, irashobora kugabanywamo ibiryo 2 bitandukanye bya Petri, ibyokurya 3 bitandukanye bya Petri, nibindi.
5. Ibikoresho byibyokurya byumuco bigabanijwemo ibyiciro bibiri, cyane cyane plastiki nikirahure.Ikirahure kirashobora gukoreshwa mubikoresho byibimera, umuco wa mikorobe, numuco wubahiriza ingirabuzimafatizo.Ibikoresho bya plastiki birashobora kuba ibikoresho bya polyethylene, bishobora gukoreshwa rimwe cyangwa inshuro nyinshi.Birakwiriye gukorerwa laboratoire, kwandika, no gutandukanya bagiteri, kandi birashobora gukoreshwa muguhinga ibikoresho byibimera.
Kuki ibiryo bya Petri bihindagurika mumico ya lithographie --—
1. Mugihe cyo gukora, hashobora kubaho ibitonyanga byamazi cyangwa bagiteri ku gipfukisho cyibiryo bya petri.Umuco wo hejuru urashobora kubuza amazi gutonyanga cyangwa mikorobe ku gipfukisho kugwa ku isahani ya petri.
2. Mugihe cyumuco, bagiteri zizabyara metabolite zimwe na zimwe zangiza imikurire niyororoka rya bagiteri mugihe cyo kubyara metabolike, kurekura ubushyuhe no gusohora amazi.Niba bagiteri zidafite umuco hejuru, ibitonyanga byamazi bizagwa mumico, bigira ingaruka kumikurire ya koloni.
3. Niba intego yumuco ari ugukusanya metabolite ya bagiteri, kandi metabolite igashonga byoroshye mumazi, umuco uhindagurika urashobora koroshya kwegeranya.
Mugihe cyumuco, hazaba imyuka myinshi yamazi mubiryo byumuco, kandi guhuza imyuka yamazi kumupfundikizo yibiryo bizatanga ibitonyanga byamazi.Niba ibiryo byumuco bishyizwe muburyo bukwiye, ibitonyanga byamazi bizatatanya ubukoloni.Muri ubu buryo, koloni nini irashobora gukwirakwira muri koloni ntoya, bigatera ibibazo bikomeye byo guhinga no kubara za bagiteri.Niba byatewe, umuco wumuco uri hejuru kandi isahani iri munsi yigitwikirizo, kandi ibitonyanga byamazi ntibizagwa kuri koloni.
Kwirinda gukoresha ibiryo bya Petri --—
1. Nyuma yo gukora isuku no kuyanduza mbere yo kuyikoresha, isuku yibyokurya byumuco igira ingaruka zikomeye kumurimo, zishobora kugira ingaruka kuri pH yumuco.Niba hari imiti imwe n'imwe, izabuza gukura kwa bagiteri.
2. Ibyokurya byumuco bishya byaguzwe bigomba kubanza gukaraba namazi ashyushye, hanyuma bigashyirwa mumazi ya 1% cyangwa 2% ya hydrochloric acide mumasaha menshi kugirango ukureho alkaline yubusa, hanyuma ukarabe kabiri n'amazi yatoboye.
3. Guhinga bagiteri, koresha amavuta yumuvuduko mwinshi (muri rusange 6.8 * 10 Pa yumuvuduko ukabije wumuvuduko wa 5), uyihindure 30min kuri 120 ℃, uyumisha mubushyuhe bwicyumba, cyangwa ukoreshe ubushyuhe bwumye kugirango uhindurwe, ni ukuvuga gushira ibiryo byumuco mu ziko, kugenzura ubushyuhe kuri 120 ℃ kuri 2h, hanyuma wice amenyo ya bagiteri.
4. Ibyokurya byumuco byonyine bishobora gukoreshwa mugutera no guhinga.

2. Mugihe cyumuco, bagiteri zizabyara metabolite zimwe na zimwe zangiza imikurire niyororoka rya bagiteri mugihe cyo kubyara metabolike, kurekura ubushyuhe no gusohora amazi.Niba bagiteri zidafite umuco hejuru, ibitonyanga byamazi bizagwa mumico, bigira ingaruka kumikurire ya koloni.
