Cov lus qhia yooj yim

Ceev cog ntoo hom zoo li poplar thiab willow muaj tej zaum zoo kawg thiab ua ib qhov biomass rau ntawm lignocellulosic ethanol zus, ib pliag tiam biofuel. Yog tus conversion rau ethanol nyuaj heev vim muaj cov lignin hauv cov ntoo. Lignin lub cev tes nrog rau lub neej puas enzymatic cellulose mus nyob, Nws yog thawj kauj ruam hauv lub conversion. Tau ntau xyoo dhau los soj ntsuam ntawm hauv VIB-UGent ua poplar ntoo nrog alterations nyob hauv lub lignin biosynthesis. Ib co noob rau hauv no biosynthesis yog downregulated uas ua rau cov ntoo uas muaj ib 20% txo nyiaj lignin. Thwmsim nrog ntoo ua nyob rau hauv ib lub tsev cog khoom tas mas pom tias cov ntoo no ua 50% xav paub ntau ethanol dua ntoo poplar zoo tib yam. Nyob rau hauv ib lub tsev cog khoom, Txawm li cas los, cov ntoo no tsis yuav caij, los nag thiab lwm stresses, yog tsis pub ua lawv hauv paus nyob hauv ib qho av. Qhov no yog vim li cas teb raug no tseem ceeb kom paub tias seb poplar tsob ntoo raug heev tau los ua tus ntoo uas yuav yooj yim dua txia mus bio-ethanol kuj tsis txawv lub neej tiag tiag.

 

Ntawm txoj kev loj hlob

Tsev cog khoom thiab tsev raug tshav.

 

Vim li cas thaiv/qeeb

Ib daim ntawv thov mus sib hais teb twb xa rau lub caij nplooj zeeg ntawm 2007 rov sim teb 2008. Daim ntawv thov no twb tsis kam nyob hauv ntuj 2008 los ntawm tsoom fwv teb chaws Belgian tub ceev xwm, raws li peb nqe lus: (1) yog cov ntaub ntawv tsis tiav, (2) tsob ntoo muaj nyob ntawm HPT tshuaj tua kab mob kuj marker, thiab (3) muaj pej xeem lus tsis zoo rau tus zus tau tej cov biofuels. Tag nrho cov lus peb tau lig dhau los tso los ntawm xeev rau sawv daws: yog lawm lub npe tsis tag, tus tub ceev xwm yuav tsis tau pib cov ntawv sai (daim ntawv thov yuav tsum tau siv siv tau thiab ua tsis tiav), lub HPT noob tau txais teb raug siv los ntawm ob lub Belgian Biosafety tswv yim thiab EFSA, thiab dav pej xeem lus uas tsis yog hais txog kev nyab xeeb yuav siv tsis tau rau daim ntawv thov mus sib ib tug neeg muaj cai tsis kam. Sawv daws xeev tshem tawm qhov tsis kam thiab tom qab tej kev sib khom lus VIB succeeded hauv phiaj ib daim ntawv tso cai rau tus teb mus sib hais hauv pib 2009. Tus teb mus sib hais pib thaum lub ntuj 2009 nrog rau ncua sij hawm ntawm ib xyoo.

 

Cov kev pab cuam foregone

Kev tshawb fawb yog ib nyuab heev thoob ntiaj teb nrog sib txeeb tsiv. Ib lub xyoos qeeb txhais tau tias lwm tus ntes los coj tau ib txoj hauj lwm rau, qab hau tias koj tsis muaj peev xwm ua tej yam yuav muaj kev ntawv. Qhov no yuav tau muaj tej yam tsis zoo rau hauv lub koom haum tau rau kev luj xyuas ywj siab, uas yuav tso siab rau nyiaj yav tom ntej. Nyob rau hauv cov ntaub ntawv no xyov tseem nqi se them nyiaj lawm ploj vim dej num xyuas kom ntxawg ruaj thiab tus kws lij choj cov nqi los npaj thiab cug tau ib rooj plaub ntawm cov Council of State (kaum tawm txhiab tus euros).

 

Nqi ntawm cov kev tshawb fawb

Xyoo ntau lab tus euros muaj lawm thov nyob rau hauv qhov kev pab cuam kev tshawb poplar.
