Lub ntsiab ntau lawm txoj kev ntawmvalineyog bio fermentation, enzymatic, tshuaj synthesis thiab protein hydrolysis extraction.
Valine tuaj yeem tsim los ntawm kev siv tshuaj lom neeg, tab sis cov tshuaj synthesis yog tus cwj pwm los ntawm cov nqi tsim khoom siab, cov tshuaj tiv thaiv nyuaj, ntau cov kauj ruam, thiab ntau yam los ntawm - khoom. Biological fermentation hloov ncaj qha rho tawm thiab tshuaj synthesis raws li txoj hauv kev tseem ceeb rau L- valine ntau lawm.
Valine Production In Poov xab
Microbial fermentation has the advantages of low cost of raw materials, high yeast yield and large-scale production. It can overcome the shortcomings of enzymatic, chemical synthesis and proteolytic extraction. This is a very economical production method. The valine produced by the fermentation method is all L-type, and does not need to be resolved by optical rotation. The strains of the fermentation method are Micrococcus glutamicum, Brevibacterium ammoniagenes, Escherichia coli, and Aerobacter aerogenes. Use glucose, urea, inorganic salts and other media. Generally, it can be produced quickly, and don't worry too much about insufficient output.
Ntawm qhov tod tes, nrog rau qhov txuas ntxiv mus thiab kev ua kom zoo ntawm biotechnology, kev ua tiav tseem ceeb tau ua nyob rau hauv kev siv tshuab lom neeg fermentation ntawm valine. Cov kev tsim tawm tsis yog tsuas yog muaj L-valine ntau lawm, tab sis kuj tsawg dua los ntawm - cov khoom. Ntxiv mus, qhov kev sib cais tom qab thiab kev ua kom huv tuaj yeem ua kom yooj yim, txo cov nqi tsim khoom.
Lub ntiaj teb L-valine kev lag luam loj thiab kev thov tau loj hlob nyob rau xyoo tas los no. Qhov sib xyaw ua ke ntawm kev loj hlob txhua xyoo ntawm pub-qib valine los ntawm 2015 txog 2020 yog 48 feem pua. Yog li ntawd, nrog rau lom fermentation raws li lub ntsiab,valinetuaj yeem ua rau ntawm qhov loj thiab tus nqi qis kom tau raws li qhov xav tau ntau dua.
