I-Microalgae ingaguqula i-carbon dioxide ku-exhaust gas ne-nitrogen, i-phosphorus, nezinye izinto ezingcolile emanzini angcolile zibe i-biomass ngokusebenzisa i-photosynthesis. Abacwaningi bangabhubhisa amangqamuzana e-microalgae futhi bakhiphe izingxenye eziphilayo ezifana nowoyela nama-carbohydrates emangqamuzaneni, angaqhubeka nokukhiqiza amafutha ahlanzekile njengamafutha e-bio negesi ye-bio.
Ukukhishwa kwe-carbon dioxide ngokweqile kungenye yezimbangela eziyinhloko zokushintsha kwesimo sezulu emhlabeni wonke. Singayinciphisa kanjani i-carbon dioxide? Ngokwesibonelo, ingabe 'singasidla'? Ungasaphathwa, ama-microalgae amancane ane "isifiso esihle" esinjalo, futhi abakwazi "ukudla" kuphela i-carbon dioxide, kodwa futhi aguqule abe "amafutha".
Ukuthola kanjani ukusetshenziswa okuphumelelayo kwe-carbon dioxide sekuyinkinga enkulu kososayensi emhlabeni jikelele, futhi i-microalgae, le nto encane yasendulo, isibe umsizi omuhle kithi ukulungisa ikhabhoni nokunciphisa ukukhishwa kwegesi ngamandla ayo okuguqula "i-carbon" ibe " amafutha”.

I-microalgae encane ingashintsha 'ikhabhoni' ibe 'amafutha'
Ikhono le-microalgae encane lokuguqula i-carbon ibe amafutha lihlobene nokwakheka kwemizimba yabo. Ama-esters kanye noshukela okunothe ngama-microalgae kuyizinto ezinhle kakhulu zokusetshenziswa zokulungiselela uketshezi oluwuketshezi. Eqhutshwa amandla elanga, i-microalgae ingahlanganisa i-carbon dioxide ibe yi-triglycerides ephezulu yamandla, futhi la ma-molecule kawoyela awakwazi ukusetshenziselwa kuphela ukukhiqiza i-biodiesel, kodwa futhi njengezinto ezibalulekile zokusetshenziswa kokukhipha i-nutrient high unsaturated fatty acids njenge-EPA ne-DHA.
Ukusebenza kahle kwe-photosynthetic kwe-microalgae okwamanje kuphakeme kakhulu kuzo zonke izinto eziphilayo eMhlabeni, izikhathi ezingu-10 kuya kwezingu-50 ukuphakama kunezitshalo zasemhlabeni. Kulinganiselwa ukuthi ama-microalgae alungisa amathani e-carbon angaba yizigidi eziyizinkulungwane ezingu-90 kanye nama-megajoules angu-1380 trillion wamandla ngokusebenzisa i-photosynthesis Emhlabeni unyaka ngamunye, futhi amandla asebenzisekayo cishe izikhathi ezi-4-5 zokusetshenziswa kwamandla omhlaba ngonyaka, ngesamba esikhulu sezinsiza.
Kuyaqondakala ukuthi iShayina ikhipha amathani acishe abe yizigidi eziyizinkulungwane eziyi-11 e-carbon dioxide minyaka yonke, ngaphezu kwengxenye yawo i-carbon dioxide ephuma ku-flue gas ekhishwa ngamalahle. Ukusetshenziswa kwe-microalgae ekuthathweni kwekhabhoni ye-photosynthetic ezinkampanini zezimboni eziqhutshwa ngamalahle kunganciphisa kakhulu ukukhishwa kwe-carbon dioxide. Uma kuqhathaniswa nobuchwepheshe bendabuko bokunciphisa ukungcoliswa kwegesi ekhishwa ngamalahle, ukuthathwa kwekhabhoni ye-microalgae kanye nobuchwepheshe bokunciphisa kunezinzuzo zezinto zokusebenza ezilula, ukusebenza kalula, kanye nokuvikelwa kwemvelo okuluhlaza. Ngaphezu kwalokho, ama-microalgae nawo anezinzuzo zokuba nenani elikhulu labantu, kulula ukulinywa, futhi akwazi ukukhula ezindaweni ezifana nolwandle, amachibi, umhlaba we-saline alkali, namaxhaphozi.
Ngenxa yekhono lawo lokunciphisa ukukhishwa kwe-carbon dioxide nokukhiqiza amandla ahlanzekile, ama-microalgae athole ukunakwa okusabalele ngaphakathi nangaphandle.
Kodwa-ke, akulula ukwenza ulwelwe oluncane olukhula ngokukhululeka emvelweni lube “izisebenzi ezinhle” zokuthathwa kwekhabhoni emigqeni yezimboni. Ungatshala kanjani ama-algae ngokwenziwa? Iyiphi i-microalgae enomphumela ongcono wokuthatha ikhabhoni? Ungathuthukisa kanjani ukusebenza kahle kwe-carbon sequestration ye-microalgae? Zonke lezi yizinkinga ezinzima ososayensi okudingeka bazixazulule.
