Chikofu - mufananidzo microbial upenyu. Mabasa uye mhando

Zvichida, zvakasikwa hapasisina survivable uye dzakashandisa hwaiitwa zvipenyu pane mabhakitiriya. Izvi unicellular upenyu siyana vanokwanisa withstanding Tichitarisa kuchinja tembiricha, kumanikidza uye acidity. Vari kwemvura kwenguva refu pasina mvura, uye pamusoro panowanikwa akanaka zvezvakatipoteredza zvinhu kamwe zvakare kudzokera dzose upenyu. Sezvo mabhakitiriya anogona kurarama apo vamwe zvinenge vanourayiwa?

Ndechipi chikofu mu zvipenyu

Utachiona vanogona kurarama yaivhuvhuta ezvinhu vachishandisa encystment. Musimboti izvi ndechokuti kwemabhakitiriya masero yakapoteredzwa gobvu nevamwe. Kutaura zvazviri, izvi ndizvo chikonzero kuti zvigare havana kutya kwemvura kana tembiricha change.

Chikofu - inzira ariko kwemabhakitiriya nako vanokwanisa kurarama pasi pokudzora rwakashata zvinhu. Urwu runodzivirira uye adaptive marongerwo kwese kwete chete nokuda prokaryotic Utachiona, asiwo vamwe protists.

Features quiescent masero

Chikofu - iri chaizvo zvakananga chimiro utachiona, iyo inotungamira dzimwe transformations mukati muchitokisi. Izvi zvinhu zviri novimba mhando encystment, asi pane zvimwe zvinoratidza mukuru kwacho. Chekutanga, sero aumbwa mukobvu vakakomba containment goko, inova chipingamupinyi kwakaomarara dzezvakatipoteredza zvinhu.

Zvisinei encystation zvachose kana zvishomanana adzikatidza kukurukurirana masero kwezvakatipoteredza, saka tusingaoneki vanofanira kugadzirira paumbwe imwe batana nevamwe. utachiona First kuunganidza fuma zvinokosha uye makemikari, izvo zvichaita kushanda kunyange encystment. Zvadaro, sero anorasikirwa zvimwe zvayo mamiriro, kuti kwekanguva zvisingakoshi panguva simba mari.

Chikofu - ndiwo mumwe nzendo upenyu kutenderera zvigare zhinji. Saizvozvowo, encystment muitiro ndiyo nguva nenguva. Vamwe cysts anogona kuramba pashure 5 kana kunyange 10 makore. Pane uchapupu hwokuti cysts kuti majemusi vanogona kurarama kwemakore 16. Rinopa kodzero kudana zvikuru akaoma musoro zvinenge panyika.

Zvinhu kuita encystation

Kudzidza mabhakitiriya ari murabhoritari ezvinhu akaratidza kuti zvakanaka mudziyo kuti kusangana yaivhuvhuta ezvinhu chikofu. Kutsunga encysted masero ari Petri ndiro pasi pokudzora siyana zvinhu zvinoratidza kukosha zvakasimba muchitokisi rusvingo. Ndezvipi zvinhu kuti paumbwe cysts?

1. Kuchinja tembiricha.

2. Change mumisasa pamusoro solutes mukati svikiro.

3. Vaporization mvura (dehumidification mvura).

4. kushaya kana nekumwisa okisijeni.

5. Kushaikwa zvokudya zvedu.

Wokupedzisira Pfungwa vanowanzochema chikonzero encystment tusingaoneki. Kana Petri dhishi kukura muhutongi utachiona, zvokudya pakupera wemari ruzhinji masero kunopfuurira dziri cysts. Kana svikiro nezvi- zvinovaka muviri, mukana encystment usingashandi.

Mamwe mapoka zvipenyu chikofu siyana uye mumamiriro ezvinhu akasiyana. Somuenzaniso, ciliates, izvi anodiwa rearrangements mudziyo renyukireya mukati muchitokisi. Encystation parasitic masero eukaryotic kunoitika kuti budai pakati pemisasa, uye kupinda kukodzera mhenyu kwezvakatipoteredza. Vamwe vamiririri prokaryotes uye eukaryotes vanoshandisa cysts kuti kubereka.

mhando encystment

Zvinangwa iro tusingaoneki zvakaitika kupinda chikofu pachikuva? Heino mhando mashomanana encystment, izvo kazhinji kuwanikwa zvakasikwa.

1. achizorora cysts.

mhando iyi mabhakitiriya uye protists vari aimirirwa encystment, sezvamakaropafadzwa sero kunzwa ezvinhu ipa zvakatipoteredza.

2. Cysts kubereka.

Iyi mhando ndiwo maitiro kuti vamiririri mazhinji ciliates. Panyaya iyi, kuti cysts vaite zvakakwana mutete Kamudzira, uye sero anotanga kugovera kakawanda. Somugumisiro, mashoko chikofu watsemuka uye chiedza anobuda vakawanda makopi rwaamai muviri.

3. Cysts kugaya.

Kwakadaro mhando masero hadziwanzowaniki mashoma rudzi zvigare. Pano chikofu - sechekushandisa zvinobudirira kugaya. Izvi mhando encystment hunhu zvipenyu, zvikara, uyo pashure "kudya" rechipfuwo kuumba ganda uye vari kutanga kugaya nyama.
