Isithombe: Igumbi Lokuvubela Elilawulwa Izinga lokushisa

Isithombe sithwebula indawo yaselabhorethri ehlelwe kahle ngokugxila okuqinile ekunembeni nasekulawuleni isayensi, sethula isigcawu esizwakala sobuchwepheshe nesimemayo. Idutshulwa ngomumo wokwakheka kwezwe, kusetshenziswa ukwakheka okulingene kanye nokukhanya okuthambile, okusabalele okukhanyisa isikhala ngokulinganayo kuyilapho kugcinwa umoya wokugxilisa ingqondo othulile. Isihloko esimaphakathi ngaphambili yigumbi lokuvutshelwa elilawulwa izinga lokushisa, elibekwe kahle ebhentshini elebhu ehlanzekile futhi eliklanywe ngezindlu ezicwebezelayo, ezinemibala e-beige ezibonakala ziqhathaniseka nekhawundari emaphakathi empunga-beige kanye nodonga olunamathayela aphaphathekile ngemuva kwayo. Leli gumbi ngokushesha lidonsa iso njengendawo eyinhloko yesithombe, elihlanganisa nomqondo wokulawulwa ngokucophelela kokushisa ngesikhathi sokuvutshelwa kwemvubelo.

Ngaphakathi kwegumbi lokuvutshelwa kuhlezi iflaski yengilazi eyi-Erlenmeyer egcwele uketshezi olucebile, olusagolide. Uketshezi luyabila, njengoba kuboniswa ukubhuquza okunamandla kanye nesivalo segwebu esimhlophe esinegwebu esakheka phezulu. Amabhamuza amancane akhuphuka ngokuqhubekayo ukusuka phansi kuye phezulu, okwenza amaphethini athambile esiphithiphithi emzimbeni okhanyayo woketshezi. I-hue efudumele yoketshezi olubilayo ikhanya ngaphansi kokukhanya okuthambile, okufanekisela ubungqabavu noguquko. Umqhele wegwebu eduze kwentamo yeflask ubonakala unomoya futhi ucwebile, okuphakamisa umsebenzi wokuvubela onempilo ojwayelekile wezinhlobo ze-yeast yase-Belgian. I-Condensation ibambelela ezindongeni zengilazi yangaphakathi ngaphezu nje kwezinga loketshezi, ibamba ukukhanya ngendlela enezela ukuthungwa okucashile nokuba ngokoqobo.

Ngaphansi kweflask, ephaneli elingaphambili legumbi lokuvutshelwa, isibonisi esincane sedijithali sifundeka ngokuthi “20.0°C” ngezinombolo ezinemibala e-amber. Lokhu kufundwa kwezinga lokushisa okunembile kuqinisa imvelo yesayensi yokusetha, okubonisa ukuthi igumbi lilawula ngokuqhubekayo izinga lokushisa lokuvutshelwa ngaphakathi kwebanga elifanele lalolu hlobo lwemvubelo. Ngezansi kwesibonisi kunezinkinobho zokulawula ezithintekayo eziphawulwe ngokuthi “SET” futhi ziboshwe ngokhiye bemicibisholo, ezibonisa ukunemba okuhlelekayo nokuphindaphinda kokuhlola. Idizayini ehlanzekile yalokhu kusebenzisana igcizelela ukulawula komsebenzisi nokunemba—izimfanelo ezibalulekile ekulawuleni ukuziphatha kwemvubelo ngesikhathi sokuvutshelwa.

Maphakathi nendawo nangemuva, okokusebenza kwelabhorethri okwengeziwe kuhlinzeka ngemininingwane yomongo futhi kudlulisele ukulungiselelwa kobuchwepheshe. Kwesokunxele, amaflaski amaningana e-Erlenmeyer namabhikha ami engenalutho phezu kwetafula, izindawo zawo ezicacile nezihlanzekile zibamba okuvelele okucashile ekukhanyeni okuthambile. Isibonakhulu esiqinile esiyinhlanganisela sihlala eduze, okuphakamisa ukuthi ukuhlaziya okuncane kakhulu kwamasampula emvubelo kungase kube yingxenye yokuhamba komsebenzi. Ngakwesokudla sohlaka, ucezu lwesisetshenziswa ngelebhu ye-analogi—okungenzeka ukuthi isisetshenziswa samandla noma isilawuli sezinga lokushisa—lihlala ngokunganaki, igeji yalo yesitayela sokudayela ingeza inhlansi yobuhle bendabuko beselabhorethri eduze kokufundwa kwedijithali kweyunithi yesimanjemanje.

Kubekwe odongeni olufakwe amathayela ngemuva kwesiteshi sokuvutshelwa ishadi elikhulu eliphrintiwe elibhalwe ukuthi “TEMPERATURE CONTROLLED FERMENTATION.” Igrafu ebonisiwe ibonisa izinga lokushisa lejika elikhuphukayo ngokuhamba kwesikhathi, elinesigaba esinomthunzi esibhalwe ukuthi “OPTIMAL FERMENTATION TEMPERATURE RANGE.” Leli shadi ligcizelela umqondo wokuqapha nokulawula ngokucophelela, ligcizelela ngokusobala ukubaluleka kokulawulwa kwezinga lokushisa ukuze kuzuzwe imiphumela yokuvutshelwa engashintshi. Amathayili odonga afana negridi ahlinzeka ngokuhlanzeka, isakhiwo esibonakalayo esiyimodulayo esenza isikhala sizizwe sihlelekile futhi sihlelekile, kuyilapho ithoni yabo ephaphathekile iwavimbela ekuqhudelaneni nemibala efudumele yoketshezi olubilayo ngaphambili.

Ukukhanya kukonke kuthambile futhi kusabalele, kuveza izithunzi ezincane futhi kugeza yonke indawo ngokukhanya okulinganayo, okungathathi hlangothi. Lokhu kudala isimo esizolile futhi esingokwesayensi kodwa esingenekayo, okuvusa umuzwa wendawo elawulwa ngokucophelela lapho ukuhlola nokunemba kwaziswa kakhulu. Ukusebenzisana phakathi kokukhanya okufudumele koketshezi olubilayo nokungathathi hlangothi okupholile kwezakhi zaselabhorethri ezizungezile kulinganisa ngempumelelo amandla nokulawula, okuqinisa umqondo wokuthi ubuciko bokwenza utshwala—ikakhulukazi lapho kusebenza imvubelo ye-ale yase-Belgian—iyachuma ngokuqondisa kwesayensi okunembayo.

Sekukonke, isithombe sikhuluma ngomqondo oqinile wobuchwepheshe, ukuhlanzeka, nokunakekelwa ngendlela. Ukuvutshelwa okusagolide okugwedlayo, okuzungezwe amathuluzi nedatha, kuba indawo ephilayo emhlabeni wokulawula okuhlelekile, okubonisa kahle ukuhlangana kwebhayoloji, ikhemistri, nobuciko enhliziyweni yesayensi yokuvutshelwa ethuthukisiwe.
