Udukoko duto dushobora guhindura dioxyde de carbone mu mwuka usohora imyuka na azote, fosifore, n'ibindi bihumanya mu mazi mabi bikavamo biomass binyuze muri fotosinthesisiyo. Abashakashatsi bashobora gusenya uturemangingo duto duto kandi bagakuramo ibice by'ibinyabuzima nka peteroli na karubohidrati mu turemangingo, ibyo bikaba bishobora kongera gukora ibicanwa bisukuye nka peteroli na gaze ya bio.
Ibyuka bikabije bya dioxyde de carbone ni kimwe mu bintu by’ingenzi bitera imihindagurikire y’ikirere ku isi. Twagabanya dute dioxyde de carbone? Urugero, dushobora 'kuyirya'? Tutibagiwe ko utunyangingo duto dufite "ubushake bwiza", kandi ntidushobora "kurya" dioxyde de carbone gusa, ahubwo tunayihindura "amavuta".
Uburyo bwo gukoresha neza dioxyde de carbone byahindutse ikibazo gikomeye ku bahanga mu bya siyansi hirya no hino ku isi, kandi microalgae, iki kinyabuzima gito cya kera, cyabaye umufasha mwiza wo gutunganya karubone no kugabanya imyuka ihumanya ikirere hamwe n'ubushobozi bwo guhindura "karubone" "amavuta".

Udukoko duto dushobora guhindura 'karubone' mo 'amavuta'
Ubushobozi bw'utubuye duto duto mu guhindura karubone mo amavuta bufitanye isano n'imiterere y'imibiri yatwo. Esters n'isukari bikungahaye kuri utubuye duto ni ibikoresho byiza cyane byo gutegura ibicanwa by'amazi. Bitewe n'ingufu z'izuba, utubuye duto dushobora gukora dioxyde de carbone muri triglycerides nyinshi, kandi utu tubuye ntidushobora gukoreshwa mu gukora biodiesel gusa, ahubwo dushobora no gukoreshwa nk'ibikoresho by'ingenzi mu gukuramo aside irike nyinshi idafite intungamubiri nka EPA na DHA.
Ubuhanga bwa microalgae mu gukora fotosynthesis muri iki gihe ni bwo buri hejuru mu binyabuzima byose ku Isi, inshuro 10 kugeza kuri 50 ugereranyije n'ibimera byo ku isi. Bivugwa ko microalgae ikora toni miliyari 90 za karuboni na tiriyari 1380 za megajoule z'ingufu binyuze muri fotosynthesis ku Isi buri mwaka, kandi ingufu zikoreshwa ni inshuro 4-5 z'ingufu zikoreshwa ku Isi buri mwaka, hamwe n'umutungo mwinshi.
Birumvikana ko Ubushinwa busohora toni miliyari 11 za dioxyde de carbone buri mwaka, muri zo zirenga kimwe cya kabiri ari dioxyde de carbone iva mu myobo ikoresha amakara. Gukoresha microalgae mu gufata carbone ikoresheje photosynthesis mu nganda zikoresha amakara bishobora kugabanya cyane imyuka ihumanya ikirere. Ugereranyije n'ikoranabuhanga risanzwe ryo kugabanya imyuka ihumanya ikirere ikoreshwa mu nganda zikoresha amakara, ikoranabuhanga ryo gufata microalgae no kugabanya imyuka ihumanya ikirere rifite ibyiza byo gukoresha ibikoresho byoroshye, gukora byoroshye, no kurengera ibidukikije. Byongeye kandi, microalgae ifite ibyiza byo kugira abaturage benshi, kuba yoroshye guhinga, no kuba ishobora guhinga ahantu nka nyanja, ibiyaga, ubutaka bwa alkali, n'ibishanga.
Bitewe n’ubushobozi bwabyo bwo kugabanya imyuka ihumanya ikirere no gutanga ingufu zisukuye, utwo tunyangingo tw’ibinyabuzima twakunzwe cyane haba mu gihugu no mu mahanga.
Ariko, ntabwo byoroshye gutuma udukoko duto dukura mu bidukikije tuba "abakozi beza" bo gukusanya karuboni ku nganda. Ni gute wahinga algae mu buryo bw'ubukorano? Ni ubuhe bwoko bw'udukoko duto bufite ingaruka nziza zo gukusanya karuboni? Ni gute wakongera ubushobozi bwo gukusanya karuboni mu gukusanya karuboni? Ibi byose ni ibibazo bigoye abahanga mu bya siyansi bakeneye gukemura.
