2. Classantiction na kayan abinci na Petri

a) gwargwadon abubuwan da aka bambanta da tasa, za'a iya raba shi cikin kwandon al'ad da tasa da kuma kwayar cuta tasa.

b) Dangane da kayan masana'antu daban-daban, an raba su cikin filastik na Petri da gilashin abincin dabbobi, amma duka biyu sun shigo da kayan abinci na Petri da kayan abinci mai watsa abinci.

c) Dangane da masu girma dabam, ana iya rarraba yawanci zuwa kwano na tsami tare da diamita na 35mm, 60mm, 90mm da 150mm da 150m.

d) Dangane da bangare daban-daban, ana iya raba su cikin kayan abinci mai tsiro 2 na rarrabe, jita-jita petri, da sauransu.

e) kayan kwanon petri an rarraba su zuwa kashi biyu, yawancin filastik da gilashi, za a iya amfani da gilashi, da gilashin al'adun microbial da al'adun dabbobi. Ana iya yin filastik na polyethylene, kuma akwai waɗanda aka zaɓa da amfani da yawa, waɗanda suka dace da ƙwayar cuta, kuma ana iya amfani da su don narkar da kayan shuka.

3. Batutuwa suna bukatar hankali a cikin amfani da kayan abinci na al'ada

A) Bayan tsaftacewa da kuma rarrabuwa kafin amfani, ko abincin petri mai tsabta ne ko kuma ba shi da babban tasiri akan aikin, wanda zai iya shafar ph na matsakaici. Idan akwai wasu sunadarai, zai hana ci gaban ƙwayoyin cuta.

b) Sabon da aka sayo kayan abinci na Petri ya kamata a rinsed da ruwan zafi da farko, sannan kuma a shafe maganin acid na 1% ko 2% na awanni da yawa don cire abubuwa masu yawa kyauta, sannan kuma sau biyu tare da ruwa mai narkewa.

c) Idan kana son yin noma Kwayoyin cuta, yi amfani da Steam Steam (gabaɗaya) na 90 ° C na zazzabi na 50 ° C na 70 ° C na 70 ° C na 70 ° C na 70 ° C na 5 na matsa lamba, ko bakara tare da bushe zafi , wannan shine, sanya kwanon dabbobi saka shi a cikin tanda kuma yana kiyaye zazzabi a kusan 120 ° C na sel na ƙwayoyin cuta don kashe ƙwayoyin ƙwayoyin cuta.

D) kawai haifuwa jies ana iya amfani dashi don inoculation da al'adu.
