Izinzuzo Zamagciwane Embonini
Imboni yanamuhla ivame ukuhlotshaniswa nemishini, ubuchwepheshe obuthuthukisiwe, kanye nezinqubo eziyinkimbinkimbi. Kodwa-ke, kukhona into yemvelo ebalulekile futhi evame ukunganakwa emikhakheni ehlukahlukene yezimboni: amabhaktheriya. Amabhaktheriya, ama-microorganism angabonakali ngeso lenyama, adlale indima ebalulekile ekuthuthukisweni kwezimboni ezahlukene. Lesi sihloko sizohlola ngokujulile izinzuzo zamabhaktheriya embonini, okuhlanganisa imikhakha yokudla neziphuzo, yezemithi, yezolimo, kanye neye-biotechnology.
Amabhaktheriya Embonini Yokudla Neziphuzo
Ukubilisa
Enye yezindlela ezaziwa kakhulu zokusebenzisa amabhaktheriya ukubilisa. Ukubilisa inqubo lapho ama-microorganism, njengebhaktheriya, eguqula khona izinto eziphilayo zibe yizinhlobo ezilula. Lesi yisinyathelo esibalulekile ekukhiqizweni kwemikhiqizo ehlukahlukene yokudla neziphuzo.
I-yoghurt ne-kefir
Amabhaktheriya e-lactic acid, njenge-Lactobacillus bulgaricus kanye ne-Streptococcus thermophilus, asetshenziswa ekukhiqizweni kweyogathi. Lawa mabhaktheriya aguqula i-lactose ibe yi-lactic acid, okwenza i-yogurt ibe nokuthungwa kwayo okuhlukile kanye nokunambitheka kwayo. I-Kefir, isiphuzo sobisi esidumile esivutshiwe, siphinde sithembele engxubeni yamabhaktheriya e-lactic acid kanye nemvubelo yokuvutshelwa.
I-Sauerkraut ne-Kimchi
Amabhaktheriya e-lactic acid, njenge-Leuconostoc mesenteroides kanye ne-Lactobacillus plantarum, nawo asetshenziswa ekukhiqizeni i-sauerkraut kanye ne-kimchi. Le nqubo yokubilisa ayigcini nje ngokunikeza ukunambitheka okuyingqayizivele kodwa futhi ikhulisa isikhathi sokugcinwa kanye nenani lokudla okunempilo kwale mikhiqizo.
Ubhiya newayini
Embonini yotshwala, amabhaktheriya e-lactic acid nawo adlala indima ebalulekile. Asetshenziswa enqubweni yokubilisa i-malolactic, eguqula i-malic acid ebukhali ibe yi-lactic acid ethambile. Lokhu kubalulekile ekukhiqizweni kwewayini elibomvu ukuze kuthuthukiswe ukunambitheka kanye nokuthungwa.
Amabhaktheriya Embonini Yezemithi
Ukukhiqizwa Kwama-antibiotic
Amabhaktheriya abe ngumthombo omkhulu wokukhiqizwa kwama-antibiotic, ama-compound asetshenziselwa ukubulala noma ukuvimbela ukukhula kwamagciwane abangela izifo. I-Penicillin, i-antibiotic yokuqala etholakale, yakhiqizwa yi-fungus i-Penicillium, kodwa ama-antibiotic amaningi anamuhla atholakala kumabhaktheriya asemhlabathini, njenge-Streptomyces. Isibonelo, i-streptomycin, i-antibiotic esetshenziselwa ukwelapha isifo sofuba, itholakala kubhaktheriya i-Streptomyces griseus.
Ukukhiqizwa Kwamavithamini
Amabhaktheriya nawo adlala indima ebalulekile ekukhiqizweni kwamavithamini. Isibonelo esivelele kakhulu ukukhiqizwa kwevithamini B12 yi-Propionibacterium kanye ne-Pseudomonas bacteria. Ukukhiqizwa kwevithamini B12 nge-microbiological kusebenza kahle futhi kunobungani nemvelo kunezindlela zamakhemikhali.
Ukukhiqizwa kwama-enzyme
Ama-enzyme ayizinto ezibalulekile ezibangela ukwakheka kwamakhemikhali ezinqubweni ezahlukene zezimboni. Ama-enzyme amaningi ebhizinisi, njenge-protease, i-amylase, ne-lipases, akhiqizwa amabhaktheriya. Lawa ma-enzyme asetshenziswa ezinhlobonhlobo zezicelo, kusukela ekukhiqizweni kwensipho kuya ekudleni naseziphuzweni.
Amabhaktheriya Kwezolimo
Ukulungiswa kwe-nitrogen
Amabhaktheriya enhlabathi, njenge-Rhizobium, ahlala ngokubambisana nezitshalo ezisawolintshi, angalungisa i-nitrogen emoyeni ayiguqule ibe uhlobo izitshalo ezingalusebenzisa. Lokhu kubalulekile ekuvundeni kwenhlabathi nasekulimeni okungokwemvelo.
Ama-biopesticides
Amabhaktheriya asetshenziswa futhi ekukhiqizweni kwemithi yokubulala izinambuzane ephilayo ukulawula izinambuzane zezolimo. I-Bacillus thuringiensis (Bt) iyisibonelo esaziwayo sebhaktheriya ekhiqiza amaprotheni abulala izinambuzane, asetshenziswa emikhiqizweni eyahlukahlukene yezibulala-zinambuzane eziphilayo.
Ukwelashwa kwe-bioremediation
Emongweni wezolimo, i-bioremediation isebenzisa amabhaktheriya ukubhidliza ukungcola okuyingozi enhlabathini nasemanzini. Amabhaktheriya akwazi ukonakalisa izibulala-zinambuzane kanye nemithi yokubulala ukhula asetshenziselwa ukuhlanza inhlabathi engcolisiwe, okwenza kube lula ezolimo eziqhubekayo.
Amabhaktheriya ku-Biotechnology
Ukukhiqizwa Kwamafutha Ezinto Eziphilayo
Amabhaktheriya asetshenziswa futhi ekukhiqizweni kwama-biofuel njenge-bioethanol kanye ne-biodiesel. Amabhaktheriya afana ne-Zymomonas mobilis asetshenziswa ekubiliseni ushukela ube yi-ethanol. Lawa mabhaktheriya anezinzuzo ngaphezu kwemvubelo ngenxa yokubekezelela kwawo i-ethanol ephezulu kanye nokuguqulwa kukashukela okusebenzayo.
Ukukhiqizwa kwe-Bioplastic
Amabhaktheriya afana neRalstonia eutropha angakhiqiza ama-bioplastic abizwa ngokuthi ama-polyhydroxyalkanoates (PHA). I-PHA iyi-polymer ebolayo engasetshenziswa njengenye indlela esikhundleni samapulasitiki avamile enziwe nge-petroleum.
Ukwelashwa Ngezakhi Zofuzo
Kwezokwelapha, amabhaktheriya asetshenziswa ekwelashweni kwezakhi zofuzo. Amabhaktheriya anjenge-Agrobacterium tumefaciens asetshenziswa njengezithuthi zokufaka izakhi zofuzo ezifiselekayo ezitshalweni. Lobu buchwepheshe buvumele ukuthuthukiswa kwezinhlobo zezitshalo ezimelana kakhulu nezinambuzane nezifo.
Isiphetho
Amabhaktheriya, yize evame ukubonwa njengosongo ngenxa yezinhlobo ezithile zezifo, empeleni ayimpahla ebalulekile emikhakheni eyahlukene yezimboni. Kusukela ekuvuthweni kokudla kuya ekukhiqizweni kwama-antibiotic, kusukela ekufakweni kwe-nitrogen kuya kuma-biopesticides, amabhaktheriya adlala indima engenakuphikiswa.
Esikhathini esizayo, ngentuthuko kwezobuchwepheshe be-biotechnology kanye nobunjiniyela bezakhi zofuzo, indima yamabhaktheriya embonini cishe izokhula. Ubuchwepheshe obufana ne-CRISPR-Cas9 buvumela ososayensi ukuhlela izakhi zofuzo zamabhaktheriya ngokunemba okungakaze kubonwe. Lokhu kuvula ithuba lokuthuthukisa izinhlobo ezintsha zamabhaktheriya ezinamakhono athuthukisiwe okusetshenziswa kwezimboni.
Ekubhekaneni nezinselele zomhlaba wonke njengokushintsha kwesimo sezulu kanye nokuvikeleka kokudla, izindlela ezisekelwe kumagciwane zinikeza izixazululo eziqhubekayo nezintsha. Ngakho-ke, kubalulekile ukuthi siqhubeke nokusekela ucwaningo kanye nentuthuko ku-microbiology yezimboni ukuze sisebenzise amandla aphelele amagciwane ukusekela intuthuko yezimboni kanye nenhlalakahle yabantu.
