Mmep?ta erythritol nke ?l? ?r? na-ejikar? usoro ?gba ?ka microbial, kama ?wep?ta ya ozugbo na osisi eke. Nke a b? n'ihi na erythritol nwere ?d?naya d? ala na okike, na mm?p?ta kp?mkwem d? ?n? ah?a na ad?gh? ar? ?r?. Nd? a b? isi usoro na isi tekn?z? maka mmep?ta nke erythritol:

Usoro mmep?ta ihe b? isi: Usoro ?gba ?ka microbial
Nh?r? nke ?d? nje bacteria

?d? isi: yist erythritol na-emep?ta d? elu (d? ka Moniliella pollinis, Yarrowia lipolytica) ma ? b? ebu (d? ka Trichosporonoides megachiliensis).
Nkwalite injinia mkp?r? nd? ihe nketa: Tekn?z? ?gbara ?h?r? na-eme ka mgbanwe mgbanwe mmanya shuga na nguzogide nr?gide osmotic d? elu nke nje nje site na mgbanwe mkp?r? nd? ihe nketa.
Nhazi ak?r?ngwa

Isi iyi Carbon: Jiri glucose ma ? b? ngw?ta sucrose (nke nwere ntinye ruru 30-35%, na-ekep?ta gburugburu osmotic d? elu iji kwalite njik? erythritol).
Tupu ?gw?gw?: Ngwa ngwa d? ?n? ala d? ka starch ?ka kwes?r? ka ? b?r? glucose site na enzymatic hydrolysis (α-amylase+amylase).
Usoro ?gba ?ka

Oxygen na-ach?kwa gbaa ?ka: Mee omimi aeration gbaa ?ka na nnukwu gbaa ?ka tank?, kpachap? anya pH (5.0-6.0), okpom?k? (28-34 ℃), na etisas?wo oxygen lar??.
Nr?gide nr?gide osmotic d? elu: N'okpuru mkpok?ta glucose d? elu, microorganisms na-agbanwe ?f?d? glucose ka ? b?r? erythritol iji dozie nr?gide osmotic cell.
Nz??kw? nd? b? isi maka nkewa na ?d? ?cha

Nk?wa tekn?z? nke nz??kw?
