Qhov sib txawv tseem ceeb ntawm Aspergillus niger thiab Aspergillus flavus yog Aspergillus niger yog ib hom ntawm cov genus Aspergillus uas tsim cov tshuaj muaj zog mycotoxins hu ua ochratoxin A thaum Aspergillus flavus yog ib hom ntawm cov genus Aspergillus uas tsim muaj zog mycotoxin B.
Aspergillus niger thiab Aspergillus flavus yog ob hom uas muaj nyob rau genus Aspergillus. Aspergillus yog ib hom fungal nrov heev uas muaj ntau pua hom pwm pom nyob rau hauv ntau qhov kev nyab xeeb thoob ntiaj teb. Cov genus no tau pom thawj zaug hauv xyoo 1729 los ntawm Italian biologist hu ua Pier Antonio Micheli. Qee hom Aspergillus paub tias ua rau cov kab mob fungal, thaum lwm tus yog qhov tseem ceeb ntawm kev lag luam.
Aspergillus Niger yog dab tsi?
Aspergillus niger yog cov kab mob muaj nyob hauv cov av, cov noob, cov khib nyiab, cov nroj tsuag rhizospheres, txiv hmab txiv ntoo qhuav, thiab txiv ntoo. Aspergillus niger yog ubiquitously pom nyob rau hauv av thiab feem ntau qhia nyob rau hauv ib puag ncig sab hauv tsev. Qee zaum, cov pwm dub tuaj yeem tsis meej pem nrog Stachybotrys. Nws yog ib hom kab ntau tshaj plaws ntawm genus Aspergillus.
Daim duab 01: Aspergillus niger
Pathogenicity ntawm Aspergillus niger tau tshaj tawm ob qho tib si hauv cov nroj tsuag thiab hauv tib neeg. Cov fungus no ua rau muaj kab mob tom qab sau qoob hauv dos thiab tuaj yeem ua rau muaj kab mob hauv cov txiv laum huab xeeb thiab hauv cov txiv hmab txiv ntoo. Txawm li cas los xij, A. niger tsis tshua ua rau tib neeg muaj kab mob ntau dua li lwm hom Aspergillus. Muaj qee zaus, A. niger tuaj yeem ua rau mob ntsws loj hu ua aspergillosis. Ntxiv mus, A. niger yog ib hom kab mob uas ua rau otomycosis lossis fungal pob ntseg. Cov kab mob fungal tuaj yeem ua rau mob, tsis hnov lus ib ntus, thiab kev puas tsuaj rau cov kwj dej thiab cov tympanic membrane. Tsis tas li ntawd, ntau hom kab mob A. niger yog siv nyob rau hauv kev lag luam kev npaj ntawm citric acid thiab gluconic acid. Ntau cov enzymes muaj txiaj ntsig xws li glucoamylase thiab qabzib oxidase kuj tau tsim los siv kev lag luam fermentation ntawm A. niger. Tsis tas li ntawd, A. niger kuj tseem koom nrog hauv kev tsim cov hlau nplaum isotopes uas muaj qhov sib txawv ntawm cov tshuaj lom neeg macromolecules rau NMR tsom xam thiab hauv kev tsim cov piam thaj biosensors.
YAspergillus Flavus yog dab tsi?
Aspergillus flavus yog hom kab mob fungal uas muaj nyob rau hauv genus Aspergillus uas feem ntau colonizing hauv av txiv ntseej, txuj lom, roj noob, thiab hauv cov txiv hmab txiv ntoo qhuav. Nws yog ib tug saprotrophic thiab pathogenic fungus nrog ib cosmopolitan faib. Aspergillus flavus yog cov kab mob fungal uas ua rau Aspergillus pob ntseg thiab cov pob rot. Nws ua rau poob loj hauv pob kws, txiv laum huab xeeb, paj rwb, thiab ntoo txiv ntoo. Hauv tib neeg, A. flavus ua rau mob granulomatous, sinusitis, keratitis, cutaneous aspergillosis, mob txhab, thiab osteomyelitis, tom qab raug mob thiab inoculation.
Daim duab 02: Aspergillus flavus
Industrially, A. flavus strain AF36, uas yog noncarcinogenic thiab aflatoxin-dawb, yog siv tshuaj tua kab raws li cov khoom xyaw nquag. AF36 yog cov tshuaj tiv thaiv kab mob fungal thiab yog siv los ua biocontrol ua lag luam rau paj rwb thiab pob kws, uas txo qis aflatoxin raug los ntawm lwm yam fungi.
Dab tsi zoo sib xws ntawm Aspergillus Niger thiab Aspergillus Flavus?
- Aspergillus niger thiab Aspergillus flavus yog ob hom ntawm cov genus Aspergillus.
- Ob hom no muaj nyob thoob plaws hauv av.
- Lawv yog cov kab mob rau cov nroj tsuag thiab tib neeg.
- Ob hom tuaj yeem tswj tau los ntawm tshuaj tua kab thiab tshuaj tiv thaiv kab mob tshwj xeeb.
- Lawv ob leeg muaj kev lag luam siv.
Qhov txawv ntawm Aspergillus Niger thiab Aspergillus Flavus yog dab tsi?
Aspergillus niger yog ib hom ntawm genus Aspergillus uas tsim cov tshuaj muaj zog mycotoxins hu ua ochratoxin A thaum Aspergillus flavus yog ib hom ntawm genus Aspergillus uas tsim cov tshuaj muaj zog mycotoxins hu ua aflatoxin B1. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Aspergillus niger thiab Aspergillus flavus. Tsis tas li ntawd, Aspergillus niger yog pwm dub, thaum Aspergillus flavus yog pwm daj.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm Aspergillus niger thiab Aspergillus flavus hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Aspergillus Niger vs Aspergillus Flavus
Aspergillus niger thiab Aspergillus flavus yog ob hom ntawm cov genus Aspergillus thiab tau piav qhia thawj zaug hauv 1729 los ntawm Italian biologist hu ua Pier Antonio Micheli. Ob hom yog pathogenic rau cov nroj tsuag thiab tib neeg. Aspergillus niger yog ib hom uas tsim muaj zog mycotoxins hu ua ochratoxin A thaum Aspergillus flavus yog ib hom uas tsim muaj zog mycotoxins hu ua aflatoxin B1. Yog li, qhov no qhia txog qhov sib txawv ntawm Aspergillus niger thiab Aspergillus flavus.
