Isithombe: Ukuvalwa kwe-Beaker nge-Golden Fermentation Liquid

Isithombe sibonisa ukusondela okumangalisayo kwebhikha yengilazi yaselabhorethri ecacile, egcwele ingxenye yoketshezi olusagolide olukhanyayo. Ibhekha imakwe ngokunyuka kokulinganisa eceleni kwayo, nezinga loketshezi elifinyelela ngaphezu nje komugqa wamamililitha angu-200. Ukwakheka kwayo okuyisilinda kanye nejika elingaphandle elincane onqenqemeni kugqamisa umklamo wayo onembile, owusizo, ogcizelela ukulungiselelwa kochwepheshe, kwesayensi lapho into enjalo ingasetshenziswa khona. Ingilazi icwebile, icace kahle, futhi ikhombisa ukukhanya okufudumele okusemaceleni okubengezela okucashile eduze kwamakhonsathi ayo, kugcizelela ukucaca kwayo kwebanga laselabhorethri.

Ngaphakathi, uketshezi olunombala osagolide lunokubukeka okuthambile, okufiphele, okukhomba ubunkimbinkimbi balo bebhayoloji noma amakhemikhali. Eduze naphansi kubhekha, ungqimba oluminyene lwenhlabathi seluzinzile—isakhiwo saso esimahhadla, esisikisela ukuba khona kweyeast esebenzayo noma enye izinhlayiyana. Lolu ungqimba olungezansi lubonakala lucishe lube yimbudumbudu, lunezimo ezihlangene ezivusa izimfanelo eziphilayo, eziguquguqukayo zezinqubo zokuphisa nokuvubela. Ngaphezu kwalesi sediment, uketshezi luyashintshashintsha, lucwebezela kancane ngaphansi kokukhanya okufudumele futhi kancane kancane lukhanya ngephimbo lubheke phezulu. Ungqimba olungaphezulu lumbozwe umugqa ontekenteke wegwebu, amagwebu alo acashile angafani nokuzola koketshezi olungezansi, okungeza isici sokulindela njengokungathi inqubo yokubila isilungele ukuphila.

Ingemuva lifiphalisiwe ngokucophelela, libeka ukugxila ngokuqinile ku-beaker nokuqukethwe kwayo. Amathoni afudumele ansundu futhi angathathi hlangothi kwangemuva adala umuzwa wokujula ngaphandle kokuphazamiseka, enikeza umoya ochwepheshile kodwa okhangayo. Ukuhlangana kokukhanya nesithunzi ebusweni boketshezi nengilazi kwengeza ukunotha ekubunjweni okubonakalayo. Ukukhanyisa, okuvela eceleni, kudala umphumela ocishe ube seshashalazini: i-sediment yenza ithunzi elimnyama ngaphakathi kwe-beaker, kuyilapho umzimba wegolide woketshezi ukhipha ukufudumala ngaphandle, ukukhiqiza ukukhanya okubonisa amandla noguquko.

Isimo sengqondo sisonke siyinhlanganisela yokunemba nokuphila okuphilayo. Izimpawu zokulinganisa ezicijile engilazini zikhuluma ngokuqina kwesayensi, izimiso eziqondile, nokunakekelwa ngokucophelela, kuyilapho inzika yemvubelo noketshezi olusagolide kuphakamisa ubuciko bokwenza utshwala, ukuvutshelwa kwemvelo, kanye nokulingana kwezinqubo zokuphila. Lokhu kuhlangana kwemishini eyinyumba enesiko eliphilayo kufaka ukuhlangana kwesayensi nobuciko. Isithombe asidlulisi nje isifinyezo sento, kodwa ukulandisa kokulindela—inkathi yokulinda phakathi kokulungiselela nomphumela, amandla angaba khona ngaphakathi komkhumbi ophethe isithembiso se-flavour, iphunga, nokuhlola ngempumelelo.

Uma sibhekwa sisonke, isithombe sikhuluma ngobungcweti, ukuziphatha, kanye nethemba. Ayixutshwanga ngamathuluzi engeziwe aselabhorethri noma izithako, esikhundleni salokho igxile esihlokweni esisodwa ngokuningiliziwe, okuyenza ifanekisele indawo yonke isayensi yokuphisa, i-microbiology, noma isifundo samakhemikhali. Ubulula bokuqamba kuthuthukisa amandla ako okuvusa inkanuko, kudonsela isibukeli emdlalweni othule wenguquko othwetshulwe ngaphakathi kwebhika laselabhorethri elithobekile.
