Amakuru

Ibyokurya bya petri ni icyombo gisanzwe cya laboratoire, kigizwe hepfo ya disiki isa neza hamwe nigifuniko, cyane cyane bikozwe muri plastiki nikirahure, kandi ikirahure gishobora gukoreshwa mubikoresho byibimera, umuco wa mikorobe ndetse n’umuco w’ingirabuzimafatizo. Ibyinshi muri plastiki birashobora gutabwa, bikwiranye no gutera laboratoire, gutondeka, no guha akato bagiteri yo guhinga ibikoresho byibimera.
Uburyo / intambwe:
1
Ibyokurya bya Petri mubusanzwe bikozwe muburyo bukomeye bwumuco wibisahani (niyo nkomoko yizina ryisahani). Umusaruro wibikoresho bya plaque ni ugushonga agar yashizwemo na sterile sterile hamwe namazi ashyushye (sterile), kuvanaho ipamba yipimisha ipamba, Genda umunwa wigituba hejuru yumuriro w itara rya alcool, hanyuma ufungure gato umupfundikizo wa sterisile ibiryo byumuco, kugirango umunwa wikizamini cyipimisha ushobora kujya kure. Iragabanijwe neza hepfo yisahani kandi yegeranye kugirango ibone umuco wisahani.

Kuberako imyororokere, iterambere no gukura kwa bagiteri bifitanye isano itaziguye nuburyo butangwa (imirire), cyane cyane kubigenzura no kubisesengura, bifite akamaro gakomeye kubwinshi bwintungamubiri zitangwa.

Ingano yimirire itangwa mugihe cyumuco wa bagiteri, niba ari imwe, kandi niba hepfo yibiryo bya petri ari byiza cyane. Niba hepfo yibiryo bya petri bitaringaniye, igabanywa ryikigereranyo cya agar rizatandukana bitewe nuburyo hepfo yibiryo bya petri biringaniye cyangwa bidahari. Isoko ntirihagije, rifitanye isano rya hafi nisesengura ryinshi, bityo rero hepfo yibiryo bya petri byuzuye birasabwa kuba byoroshye kubera impamvu. Nyamara, kubiranga rusange (kugenzura za bagiteri, gukura kwa koloni, kubyara, nibindi), ibiryo bisanzwe bya petri birashobora gukoreshwa.
Kwirinda
Nyuma yo gukora isuku no kuyanduza mbere yo kuyikoresha, niba isahani ya petri isukuye cyangwa idafite isuku ikomeye kumurimo, ishobora kugira ingaruka kuri pH yikigereranyo. Niba hari imiti imwe n'imwe, bizabuza gukura kwa bagiteri.
