Isithombe: I-Active Beer Fermentation in Laboratory

Lesi sithombe sithwebula isikhashana sokuhlola okuguquguqukayo ngaphakathi kwelabhorethri yokuvubela ehlelwe kahle, lapho imingcele phakathi kokwenza utshwala obuvamile nesayensi yesimanje ifiphalisa ibe indaba eyodwa, ephoqelelayo. Enkabeni yokwakheka kunomkhumbi wokuvubela omkhulu, osobala kancane, ogcwele uketshezi olunenhlaka esagolide oluzungezayo futhi olunamabhamuza ngamandla abonakalayo. Igwebu elivele phezulu kanye nokunyakaza ngaphakathi koketshezi kuphakamisa inqubo esebenzayo yokuvutshelwa, eqhutshwa isiko eliqinile lemvubelo eligaxa ushukela lube utshwala nesikhutha. Ukufiphala koketshezi kanye nokuthungwa kwalo kusikisela kusisekelo esicebile sewort, okungenzeka ukuthi kufakwe ama-malt akhethekile noma izithasiselo, eziklanyelwe ukuhlanganisa amaphrofayili e-flavour ayinkimbinkimbi ngokuguqulwa kwe-microbial.

Okunamathiselwe emkhunjini kunokhiye wokuvutshelwa, ingxenye encane kodwa ebucayi evumela amagesi ukuba abaleke kuyilapho kuvimbela ukungcola okuphuma emoyeni ukuba kungangeni. Ukuba khona kwayo kugcizelela ukulingana phakathi kokuvuleka nokulawula okuchaza ukuvutshelwa okuphumelelayo-lapho umkhumbi kufanele uphefumule, kodwa kuphela ngendlela egcina ubuqotho besiko ngaphakathi. Ilokhi ibhamuza kahle, ukushaya kwenhliziyo okunesigqi okubonisa umsebenzi we-metabolic ngaphakathi, futhi isebenza njengenkomba yokubuka kumenzi webhiya noma umcwaningi oqaphe inqubo.

Okuzungeza umkhumbi omaphakathi kukhona amathuluzi akhethiwe wesayensi nezinto zengilazi, ngayinye enomthelela ekuqineni kokuhlaziywa kwemvelo. Kwesokunxele, iqoqo lamaflaski e-Erlenmeyer namabhika aqukethe uketshezi olucacile nolunhlaka, okungenzeka ukuthi amasampula athathwe ezigabeni ezihlukene zokuvutshelwa noma izixazululo zezakhi ezilungiselwe ukusakazeka kweyeast. Isibonakhulu sihlala eduze, ubukhona baso buphakamisa ukuthi ukuhlaziya amaselula kuyingxenye yokuhamba komsebenzi—mhlawumbe ukuhlola ukusebenza kwemvubelo, ukubona ukungcola, noma ukubona izinguquko ze-morphological ngaphansi kwengcindezi. Kwesokudla, imitha yedijithali ene-probe—okungenzeka iyinzwa ye-pH noma izinga lokushisa—ima ilungele ukukala amapharamitha abalulekile, iqinisekisa ukuthi ukuvutshelwa kuhlala ngaphakathi kobubanzi bayo obufanele.

Ngemuva, isigameko siyakhula ukuze sifake amaflaski e-Erlenmeyer engeziwe kanye nebhodi lebhodi eligcwele amanothi abhalwe ngesandla nemidwebo. Igrafu edwetshwe kulo lonke ibhodi ibonakala ilandelela ukuqhubeka kokuvutshelwa ngokuhamba kwesikhathi, neziguquguqukayo ezifana nezinga lokushisa nomsebenzi we-microbial ohlelwe ngokuhlobene. Lokhu okwasemuva kwengeza ukujula nomongo, kufaka isilingo ngaphakathi kohlaka olubanzi lokubuza nokubhala. I-incubator elawulwa izinga lokushisa noma isiqandisi nayo iyabonakala, ifaka i-glassware eyengeziwe futhi iphakamisa ukuthi amaqoqo amaningi noma izinhlobo ziyafundwa kanyekanye.

Ukukhanya kulo lonke igumbi kufudumele futhi ku-amber-toned, kuveza izithunzi ezithambile futhi kuthuthukisa imibala esagolide yoketshezi olubilayo. Lokhu kukhanya kudala umoya wokuzindla, kumeme isibukeli ukuthi sibambezele futhi sibambe imininingwane. Ivusa umuzwa wokugxila okuthulile, lapho ithuluzi ngalinye, ibhamuza ngalinye, nephoyinti ledatha ngalinye linikela ekuqondeni okujulile kwesayensi yokuvutshelwa.

Sekukonke, isithombe sidlulisa isimo sengqondo sokunemba, ilukuluku, noshintsho. Kungumfanekiso wokuvutshelwa njengokubili isenzakalo sebhayoloji kanye nokuzizwisa okuklanyiwe, lapho imvubelo ingeyona nje isithako kodwa ingumhlanganyeli ekudaleni ukunambitheka. Ngokwakhiwa kwaso, ukukhanya, kanye nemininingwane, isithombe sibungaza ukuphambana kwesiko nokuqanjwa kabusha, simema umbukeli ukuthi ajabulele inkimbinkimbi nobuhle bokwenza utshwala njengomkhakha ogxile kukho kokubili ubuciko nesayensi.
