Isithombe: Amaseli wemvubelo ekuvutshelweni

Kulokhu okusondelene okumangalisayo, amandla okuphila angabonakali abangela ukuphisa abonakala ngemininingwane emihle, eguqula inqubo yezinto eziphilayo ibe into ecishe ifane nesithombe esiqoshiwe. Inqwaba yamaseli ayisiyingi ayi-oval yeast, ngalinye lilungiswe kahle futhi line-contour ehlukile, lintanta oketshezini olunothile lwe-amber, amathoni awo asagolide anomhlaba enanela imfudumalo yendawo ezungezile. Amanye amaseli akhukhulela phezulu, athwalwa amabhamuza amancane aphumayo abambelela endaweni yawo ngaphambi kokuba agqashuke ukuze akhuphukele ekukhanyeni. Ezinye zihlala zingamaqoqo athambile, aboshelwe imisinga engabonakali ngaphakathi koketshezi, njengokungathi kudanswa umphakathi kancane kancane. Ibhamuza ngalinye liyabenyezela njengoba libamba ukukhanya kokufudumala, lisakaza umuzwa wokunyakaza namandla endaweni yesehlakalo. Umdlalo wokukhanya ubalulekile lapha—uthambile futhi usagolide, ugcwalisa kokubili uketshezi nemvubelo ngekhwalithi ekhanyayo, okwenza konke ukwakheka kuzwakale kuphila futhi kunamandla, njengokungathi umbukeli ubona ukuvutshelwa ngesikhathi sangempela.

Ingaphambili elinemininingwane ebukhali libeka imvubelo phakathi nendawo yokunaka, okuvumela umbukeli ukuthi ahlole ingaphandle lemibalabala nokuhluka okucashile, kodwa ukujula kwenkundla kuncipha kancane kube ukuthamba, kuqondise iso ngasemuva elifiphele. Lapho, uhlaka oluncane lwezinto zengilazi—mhlawumbe iflaski noma ibhika—lunikeza umongo, ongagcini nje ku-microcosm yoketshezi kodwa ngaphakathi kohlaka olubanzi lwelabhorethri noma indawo yokuphisa utshwala. Leli phuzu lesakhiwo esisemuva kwezinto ezintantayo liqinisa imvelo embaxambili yokuvutshelwa kwakho kokubili ubuciko nesayensi: inqubo egxile empilweni yemvelo kodwa ecwengisisiwe futhi eqondiswa ukuqonda komuntu.

Uketshezi olunhlaka ngokwalo lucebile ngokuhluka, olubenyezela ngamagreyidi egolide, uju, namathoni e-caramel anyakazayo ngokudlala kokukhanya. Ukucaca kwawo kuphawulwa amabhamuza angenakubalwa akhuphukayo, ngalinye liwumfanekiso obonakalayo womsebenzi we-yeast metabolism. I-effervescence yenza okungaphezu kokwengeza ukuthungwa—ifanekisela ukuguquka, isikhathi lapho ushukela uguqulwa ube utshwala nesikhutha, isimangaliso seminyaka eyikhulu esichaza ubuciko bokwenza utshwala. Igwebu elinamagwebu eliqala nje ukumila endaweni yoketshezi liyisikhumbuzo sokuthi la mandla abhuquzayo azokhiphani ekugcineni: ubhiya, isiphuzo esiyinkimbinkimbi eqala ngezikhathi ezifana nalesi.

Ukuqanjwa akudluliseli nje ukunyakaza kodwa ukusondelana. Ukufakazela imvubelo kulesi sikali ukubona ukuphisa kukhishelwa ubunjalo bawo obuphilayo, izinto eziphilayo zembula njengabasebenzi abangabonakali beqhuba ukuvutshelwa phambili. Ukuhleleka kwazo oketshezini, kungakhathaliseki ukuthi kuku-swirls okuxegayo noma amafindo aqinile, kuphakamisa isigqi esibukisa izimiso zemvelo, ezimazombezombe uma ubuka nje kuqala kodwa ezibuswa ukuvumelana kwesayensi yezinto eziphilayo. Izizwa ngokuzenzakalelayo futhi inembe, idla amagalane ngobungqabavu bayo kodwa ilawulwa ngaphakathi komkhumbi oklanyelwe ukuhambisa lawo mandla.

Kunenkondlo ethule yokulinganisa phakathi kokugxila nokufiphala, phakathi kwamaseli eyeast anikezwe ngokucijile kanye nengemuva elithambile lemikhumbi yengilazi. Lokhu kuhlangana kugcizelela ukuvumelana phakathi kokungabikezeli kwemvelo kanye nokuqeqeshwa kwesayensi. I-yeast ayintanti, isabela kumabhamuza nemisinga, nokho indawo yazo yakhiwe ngokucophelela: uketshezi olunothile ngezakhi, izinga lokushisa elifanele, umkhumbi oklanyelwe ukukhuthaza umsebenzi wabo ngenkathi uqukethe. Inqubo yokuphisa iphenduka inkhulumomphendvulwano phakathi kwenhloso yomuntu kanye nomsebenzi we-microbial, lapho yonke ibhamuza elikhuphukayo liwubufakazi bokuqina nokuphila nokuzivumelanisa nezimo.

Ekugcineni, isithombe sizwakala njengokungaphezu nje kocwaningo lwesayensi—ukuzindla ngobuciko ngoguquko. Ukukhanya okusagolide, ukuphakama kwamabhamuza, amangqamuzana emvubelo aqoshiwe konke kukhuluma ngoshintsho, ngezithako ezingavuthiwe eziba yinto enkulu ngokusebenza okungabonakali. Ithwebula umkhawulo wokwenza isiphuzo, lapho imvelo nomsebenzi wezandla kuhlangana khona ngomdanso kokubili okubonakala kuncane kakhulu kanye nesikhumbuzo. Uma simi ngaphambi kwalesi senzakalo, umuntu uyakhunjuzwa ukuthi yonke ingilazi kabhiya iphethe phakathi kwayo amazwibela alokhu kuhlangana okuntekenteke, kwamangqamuzana imvubelo alenga ekukhanyeni kwe-amber, esebenza ngokungakhathali ku-symphony yawo ethule, epholile.
