Ntuj Vanillin

Tsis Muaj: 121-33-5

HS Code: 29124100

Einecs Tsis Tau: 204-465-2

MF: C 8 H 8 O 3

Kev kawm thiab kev siv:

Ntuj vanillin ntau lawm los ntawm kev siv roj ntsha. (Streptomyces setonii) hauv Streptomyces V-1 siv tau ferulic acid ua ntej, biotransformation ntawm vanillin. Daim ntawv thov cov kua tshuaj NaOH yuav npaj tau cov dej haus kua dej muaj zog ntxiv rau hauv V-1 pom, peb tuaj yeem hloov tau ferulic acid rau cov tshuaj vanillin, tsuas yog cov khoom siv tsawg dua xwb. V-1 nruab nrab carbon thiab nitrogen qhov system, tau qhov siab tshaj plaws tus nqi ntawm 66.2%. cell concentration thiab transformation system ntawm pH muaj zoo kawg rau lub transformation nyhuv. Ntxiv adsorption resin tuaj yeem txo qhov concentration ntawm cov tshuaj tiv thaiv cov tshuaj ntawm vanillin, txo cov nyhuv toxic ntawm cov xovtooj ntawm tes; nyob rau hauv cov khoom noj khoom haus batch, qhov kawg concentration ntawm vanillin lub transformation system tau ncav cuag 1.74%. yuav siv rau biotransformation ntawm isoeugenol los vanillin los ntawm lwm tus precursor. Ib hom tawv nqaij ntawm Bacillus pumilus (Bacillus pumilus) S-1 tuaj yeem sib txawv Qhov muag ntawm eugenol vanillin. Los ntawm kev siv TLC, GC, LC, GC-MS, LC-MS tsom xam qauv thiab sab chromatography thiab ua rau kev ntsuam xyuas ntau ntawm S-1 koom nrog cov isoeugenol metabolites. Txoj kev hloov dua siab tshiab nyob hauv ib feem ntawm isoeugenol monomers rau hauv ob lub hnab thiab peb lub innings thiab nkag mus rau txoj kev qhov kev degradation; thiab raws li kev soj ntsuam ntawm cov khoom uas yog isugugenol thiab ib txoj kev los ntawm cov metabolism hauv vanillin. Thiab tej zaum yuav tau kuaj rau isoeugenol mus rau hauv cov khoom nruab nrab ntawm vanillin txoj kev, speculated nws mus rau hauv xyab
