Morphology thiab physiology ntawm Aspergillus niger

Aspergillus niger nceb yog dab tsi? Lawv muaj peev xwm coj cov cag thiab loj hlob mus rau hauv ib cheeb tsam txawm tias qhov kub siab tshaj +40 0С. Tus nqi ntawm nceb ripening thaum lub sij hawm ntes ntawm cov cheeb tsam loj yog tsuas yog tshwj xeeb - nyob rau hauv peb hnub. Tsaus, tau txais cov yam ntxwv tsaus grey lossis xim dub, cov kab mob zoo li conidia mature - microscopic formations nyob rau sab saum toj ntawm cov thickened conidial taub hau ntawm cov kab mob parasitic.

Lub morphology ntawm Aspergillus niger suav nrog ntau hom pwm dub uas xaiv sab hauv tsev, zaub mov, lossis txawm tias tib neeg lub cev.

ib puag ncig zoo rau pwm dub

Mould spores muaj nyob txhua qhov chaw, lawv tsuas yog nyob hauv ib puag ncig ntawm kev ua kom tsis muaj menyuam lossis lub tshuab nqus tsev. Cov khoom sib cais los ntawm mycelium hover hauv huab cua thiab pib musnquag muab ntau qhov chaw uas cov spore tuaj yeem ntes tau thiab mus tsis pom.

Cov pwm nws tus kheej yog tsim los ntawm ob lub cev filamentous, ib qho uas tsim cov vegetative tsim, thiab lwm yam stretches upwards thiab, ripening, muab lub neej rau tshiab spores.

Cov yam tseem ceeb uas ua rau muaj txiaj ntsig zoo ntawm Aspergillus niger:

  • tsis muaj qhov nkag thiab tawm ntawm huab cua ntshiab; qhov no tsim kom muaj cua txias, fumes-laden huab cua uas zoo tagnrho rau kev txhim kho ntawm ntau pawg ntawm pwm;
  • Hummidity ze rau 100% yog ib qho ntawm cov xwm txheej uas pom muaj Aspergillus niger;
  • ntse kub hloov pauv, tsim kom muaj chav thiab condensate;

Ntxiv rau, ib qho ntawm cov khoom yog qhov tsis muaj nruj ntawm cov pob khoom noj.

Tsis muaj pwm zoo ib yam thaum saib hauv lub tshuab tsom. Qhov kev nthuav qhia thiab kev ntshai ntawm cov pwm dub ua rau pom qhov txawv ntawm lub teeb-xim fluffy pob ntawm Aspergillus ntawm lwm yam, uas zoo li tsis tshua muaj kev phom sij, tab sis qhov no yog kev xav tsis zoo. Lub mycelium ntawm ob peb hom tuaj yeem dub ib zaug, nyob ntawm lub sijhawm ntawm kev loj hlob ntawm cov kab mob, hom ntawm qhov chaw npog thiab tus nqi ntawm kev sib kis ntawm cov cheeb tsam.

Muaj hom Aspergillus niger:

  • Cov xim ntawm mycelium yog lub teeb, tsuas yog cov spores paub tab yog xim dub. Xws li ib tug fungus nyob hauv qhov tsaus ntuj nti ntawm cov chaw nyob thiab tsis nyobHauv tsev thiab yog qhov ua rau aspergillosis.
  • Phoma - yog hais txog 4 pawg kab mob. Nyob rau hauv lawv, ntawm qhov tsis tooj, lub cev vegetative yog ib tug dub blob nrog ib tug dawb ntug ntawm mature spores.
  • Tom ntej no saib ib txwm muaj xim tsaus nti nplua nuj. Sib cais spores txaus siab nyob rau hauv tib neeg lub plab zom mov thiab ua rau intoxication thiab ib tug pronounced tsis haum tshuaj.
  • Muaj ib hom xim tsaus nti txaus ntshai thiab tsis tshua muaj zog, tab sis tib lub sijhawm yuav luag tsis txaus ntshai rau tib neeg noj qab haus huv.
  • Ntawm cov hom pwm dub yog cov nceb penicillin, feem ntau loj hlob hauv cov kev hloov pauv nyuaj kom tau txais cov khoom muaj txiaj ntsig raws li cov tshuaj tua kab mob tsim.
  • hom mycelium hauv qab no zoo li slimy plaque me ntsis uas tshwm sim ntawm cov zaub ntev ntev, txiv hmab txiv ntoo, txiv ntoo.

Yog li Aspergillus nigeria tsis yog ib yam khoom ntawm kev quaj ntsuag tob uas peb paub. Ib qho ominous fungus tuaj yeem nkaum hauv qhov tsis muaj teeb meem dawb paug.
