Isithombe: Ukuvutshelwa kwemvubelo ku-wort

Lesi sithombe sinikeza umbono othakazelisayo wedrama encane yokuvutshelwa, lapho ibhayoloji nekhemistri kuhlangana khona kubhekha wengilazi ogcwele i-golden-hued wort. Umkhumbi, okungenzeka ukuthi uyiflaski yakwa-Erlenmeyer, ugcwele ingxenye yoketshezi olukhazimulayo nge-amber tint efudumele, ephakamisa isisekelo esicebile se-malt esilungiselelwe ukujova imvubelo. Okulengiswe ngaphakathi koketshezi kunezinhlayiya eziningi eziyindilinga—amaseli emvubelo—ngalinye lihluka kancane ngosayizi nokusabalalisa. Lezi zinhlayiya azimi ndawonye; abonakala enyakaza, egqugquzelwa ukukhuphuka kancane kwamabhamuza e-carbon dioxide acwebezelayo njengoba ekhuphuka. Ukusebenzelana phakathi kwemvubelo kanye newort kuyashintshashintsha futhi kunezingqimba, uhlelo oluphilayo olubanjwa ngomzuzwana wenguquko.

Amangqamuzana imvubelo ngokwawo enziwa ngokucacile okuphawulekayo, amafomu awo ayindilinga antanta njengamaplanethi amancane emthaleni obonakalayo wezakhi noshukela. Ngaphansi kokukhuliswa okuphezulu, izindonga zamangqamuzana awo abonakala enziwe ngendlela eyinkimbinkimbi futhi eyinkimbinkimbi, okusikisela emishinini yezinto eziphilayo ngaphakathi—ama-organelle asebenza ngokuzikhandla ukuguqula ushukela ube yinhlanganisela ye-ethanol ne-flavour. Amanye amangqamuzana ahlangana ndawonye, ngokunokwenzeka ageleze ephendula izimpawu zemvelo, kuyilapho amanye ehlala ehlakazekile, ebilayo. Lokhu kwehlukahlukana okubonakalayo kuphakamisa ukuthi isithombe singase sibhala ukusebenza kwemvubelo ngaphansi kwezimo ezihlukahlukene, mhlawumbe siqhathanise ibanga lokushisa, ukutholakala kwezakhi, noma amazinga komoyampilo. Ukuba khona kwamabhamuza akhuphuka phansi eflaskini kwenezela olunye ungqimba lomsebenzi, okubonisa ukuthi ukuvutshelwa kuyaqhubeka nokuthi imvubelo inamandla okusebenza komzimba.

Ukukhanya esithombeni kuthambile futhi kusabalele, kusakaza ukukhanya okuthulisiwe oketshezini lonke kanye nezinhlayiya ezimisiwe. Lokhu kukhethwa kokukhanya kuthuthukisa ithoni yesayensi yokuqanjwa, kudala isimo esizolile, sokucabanga esimema ukubhekwa eduze. Izithunzi zincane, okuvumela isibukeli ukuthi sigxile emininingwaneni eyinkimbinkimbi engaphakathi kweflask. I-engeli yekhamera, etshekile kancane, yengeza ukujula nokubuka, okwenza amaseli ayindilinga yeyeast abonakale enamacala amathathu futhi igcizelela ubudlelwane bawo bendawo noketshezi oluzungezile. Lokhu kubuka okune-engeli kuphinde kudonsele ukunaka ekumaka kokulinganisa—“400”—okumiswe eduze kwaphezulu kweflask, okuqinisa ngobuqili isimo esilawulwayo, sokuhlola sesehlakalo.

Ngemuva, nakuba kufiphalisiwe, kukhona amacebo endawo yaselabhorethri—mhlawumbe amashalofu afakwe izinto ezivuselelayo, amathuluzi, noma izinto ezibhalwe phansi. Lo mongo ubeka isithombe endaweni yokubuza nokunemba, lapho okuguquguqukayo ngakunye kulandelelwa futhi ukubhekwa ngakunye kunomthelela ekuqondeni okubanzi kwesayensi yokuvutshelwa. Ukwakheka sekukonke kujabulisa ngobuhle futhi kuyaheha ubuhlakani, kulinganisa ubuhle obubonakalayo nokujula kobuchwepheshe.

Sekukonke, isithombe sidlulisa umuzwa wenhlonipho ngenqubo yokuvutshelwa, sigqamisa ubunkimbinkimbi nobuhle bokuziphatha kwemvubelo esimweni sokuphisa. Kungumfanekiso wempilo ye-microbial in motion, isifundo soguquko lapho izinqubo ezingabonakali zibonakala ngokubhekisisa ngokucophelela. Ngokukhanya kwaso, ukwakheka, nezinto ezixoxwa ngazo, lesi sithombe simema isibukeli ukuba sazise ubuciko nesayensi yokwenziwa kobhiya, lapho ibhamuza ngalinye, ingqamuzana ngalinye, nokusabela ngakunye kunendima ekuklameni ukunambitheka, iphunga, nomlingisi. Kungumkhosi wokugubha amandla angabonakali alolonga izinzwa zethu, kanye nokuhlonipha umsebenzi wokucophelela owenza aphile.
