Isithombe: Ukuvutshelwa kobhiya okusebenzayo eLebhu

Lesi sithombe sithwebula isikhashana soshintsho olunamandla lwe-biochemical ngaphakathi kwesilungiselelo selabhorethri ehlelwe kahle, lapho ubuciko bokuvutshelwa bukhushulelwa kumsebenzi wesayensi onembile nolawulwayo. Enkabeni yokwakheka kukhona umkhumbi wengilazi obilayo, izindonga zawo ezibonisa ngale ziveza uketshezi olusagolide, oluphumayo phakathi kokuvutshelwa okusebenzayo. Ingaphezulu loketshezi lithweswe ungqimba lwegwebu olunamagwebu, kuyilapho imifudlana yamabhamuza amahle ikhuphuka ngokuqhubekayo ukusuka ekujuleni, ibamba ukukhanya okuzungezile futhi idale ukuthungwa okuguquguqukayo okukhuluma namandla okwenziwa kwe-metabolic kwesiko leyeast ngaphakathi. Lolu ketshezi lucwebezela ukufudumala, umbala walo wenhlaka osikisela isisekelo sewort esicebile nge-malt, okungenzeka sibe ilaza yohlobo lwaseJalimane noma omunye ubhiya oklanywe ngokucophelela.

Umkhumbi ufakwe i-airlock, idivayisi encane kodwa ebalulekile evumela i-carbon dioxide ukuphuma ngenkathi ivimbela ukungcola ekungeneni. Ukuba khona kwayo kugcizelela ibhalansi ethambile edingekayo ekuvubeleni—lapho indawo ezungezile kumelwe ivuleke kokubili ukuze idedelwe futhi ivaleke ekungeneni. Ukubhuquza ngaphakathi komkhumbi akusona isiphithiphithi kodwa kunesigqi, uphawu lomsebenzi wemvubelo enempilo kanye nezimo ezigcinwe kahle. Igwebu elingaphezulu liwugqinsi futhi linokhilimu, libonisa ukuxhumana phakathi kwamaprotheni nemvubelo, futhi ukunyakaza okuzungezayo ngaphakathi koketshezi kuveza umuzwa wokujula namandla, njengokungathi isiphuzo ngokwaso siyaphila futhi siyashintsha.

Eceleni komkhumbi, isilinda esineziqu sima siqondile, imigqa yaso ehlanzekile kanye nezimpawu eziqondile eziphakamisa ukuthi ukukalwa nokubhekwa kuyingxenye yenqubo. Leli thuluzi cishe lisetshenziselwa ukuqapha umthamo, ukuqoqa amasampula, noma ukulungisa izixazululo zezakhi, okuqinisa ukuqina kwesayensi okuchaza lesi sikhala. Indawo yensimbi engaphansi kwempahla ikhombisa ukukhanya okufudumele, ingeza ungqimba lokucaca okubonakalayo futhi igcizelela ukuhlanzeka nokuhleleka kwendawo yokusebenza.

Ngemuva, amashalofu afakwe ingilazi kanye namajenali esayensi anezela isisindo sobuhlakani endaweni yesehlakalo. Izitsha zengilazi—amabhika, ama-flask, nama-pipette—ahlelwe ngendlela enembile, alungele ukusetshenziswa ekuhlaziyeni noma ekuhlolweni okwengeziwe. Amajenali, umgogodla wawo uqondaniswe kahle, aphakamisa ukujula kolwazi nokuzibophezela ekufundeni okuqhubekayo. Ukukhanyisa kule ndawo kufudumele futhi kugxilile, kuveza izithunzi ezithambile futhi kudala isimo sokucabanga esimema ukubuza nokuzindla.

Ingqikithi yokuqamba ibhalansile futhi yenziwe ngamabomu, iqondisa iso lesibukeli ukusuka oketshezini olugezayo olungaphambili ukuya kumathuluzi nemibhalo engemuva. Idlulisela isimo somoya onokuthula, lapho okuguquguqukayo ngakunye—izinga lokushisa, isikhathi, uhlobo lwemvubelo, nokwakheka kwezakhi—kulinganiswa ngokucophelela ukuze kufinyelelwe umphumela othile. Lokhu akusona isiphuzo esivamile kodwa inqubo eqhutshwa ngamabomu, eqhutshwa idatha, lapho isiko lihlangabezana nokuqamba okusha nalapho ukubhekwa ngakunye kunomthelela ekuqondeni okujulile kwesayensi yokuvutshelwa.

Ekugcineni, isithombe siwumkhosi wokugubha ukuhlangana phakathi kwebhayoloji nobuciko. Ihlonipha umsebenzi ongabonakali we-yeast, ukunemba kwamathuluzi esayensi, kanye nelukuluku lomuntu eliqhuba ukuhlola. Ngokukhanya kwawo, ukwakheka kwawo, nemininingwane yawo, lesi sithombe sixoxa ngendaba yenguquko—yokuba ushukela uphenduke utshwala, uketshezi lube ubhiya, nolwazi lube ukunambitheka. Imema umbukeli ukuthi athokozele ukuvutshelwa hhayi nje njengenqubo, kodwa njengokubambisana okuphilayo, okuphefumulayo phakathi kwemvelo nenjongo.
