Isithombe: I-Yeast Culture Storage in a Cellar

Lesi sithombe sivusa umuzwa wobuciko obungapheli kanye nenhlonipho ethule, ebekwe phakathi kwe-rustic ye-cellar ekhanyiswe kalufifi. Lesi sikhala sichazwa ngendlela esakhiwe ngayo umhlaba kanye nokukhanya okuphansi, lapho imigqa yezimbiza zengilazi iklelisa amashalofu okhuni aguquguqukayo anwebeka ezindongeni. Imbiza ngayinye igcwaliswa ngoketshezi olunombala osagolide olukhazimula kancane ngaphansi kokukhanya okufudumele kokukhanya okungaphezulu okukodwa, okubonisa ukukhanya okuthambile kanye namathunzi amade, aguquguqukayo anyakazayo egumbini. Izimbiza zihlelwe ngokucophelela, ukufana kwazo akusikiseli nje ukugcinwa, kodwa ingobo yomlando ekhethiwe yokuvutshelwa—umkhumbi ngamunye isahluko endabeni eqhubekayo yokuguqulwa kwamagciwane.

Ngaphambili, imbiza eyodwa ihluke kwenye, ibekwe ngokugqama phezu kwetafula lokhuni elinezimpawu zeminyaka yokusetshenziswa. Isivalo saso sisusiwe, sibonisa indawo enamagwebu, egwedla kancane ebonisa isiko le-yeast ephilayo ngaphakathi. Uketshezi olungaphakathi luyaphila, ubuso balo buboniswa ukukhishwa kancane kwesikhutha, okuwuphawu olubonakalayo lokubila oluqhubekayo. Igwebu lithambile kodwa liyaphikelela, lenza ungqimba olunokhilimu olukhuluma ngempilo nokusebenza kwemvubelo. Eceleni kwembiza, isitsha esincane nesivalo esisusiwe kuphumule ngokuthula, okusikisela ukuxhumana kwakamuva—mhlawumbe isampula lidwetshiwe, isiko laphakelwa, noma inqwaba yahlolelwa ukuthi ilungile yini. Lesi sikhathi sokumisa isikhashana, esithwetshulwe ngokuthula kwesithombe, simema ukuzindla ngobudlelwane obuseduze phakathi kwezandla zomuntu nempilo yamagciwane.

Igumbi elingaphansi komhlaba ngokwalo lingene shí emkhathini. Amashalofu okhuni, amadala futhi angalingani, anikeza ubuqiniso obuthintekayo endaweni yesigameko. Izindawo zabo ziba mnyama ngenxa yesikhathi nokusetshenziswa, futhi izithunzi abaziphonsayo zidala isigqi sokukhanya nobumnyama esithuthukisa umuzwa wokujula nokuvaleleka. Izindonga azibonakali, zimbozwe umthunzi, okuvumela izimbiza nokuqukethwe kwazo kuthathe indawo emaphakathi. Ukukhanyisa kuthambile futhi kuyaqondisa, kugxile kumabhodwe kanye netafula, kudala isigaba esibonakalayo esidonsela iso lombukeli embizeni ebhayizayo ngaphambili kuyilapho lisavuma ubukhona obuthule babanye.

Lesi silungiselelo singaphezu kwendawo yokugcina—iyindawo engcwele yokuvubela, indawo lapho ibhayoloji nesiko kuhlangana khona ngenqubo ehamba kancane, eyenziwe ngamabomu yokuguqulwa. Uketshezi olusagolide olungaphakathi kwezimbiza lungaba uju, i-mead, noma i-yeast starter ekhethekile, kodwa ubunikazi balo ncamashi buhambisana nesimo esiwuvusayo. Okubalulekile ukunakekela okusobala ekulondolozweni kwakho, inhlonipho ekhonjiswa enqubweni, nokuqonda ukuthi ukuvutshelwa akukhona nje ukusabela kwamakhemikhali kodwa kuwukubambisana okuphilayo, okuphefumulayo phakathi kwemvelo nenjongo.

Isithombe sidlulisa umoya wokuzindla ngokuthula kanye nelukuluku lesayensi. Imema umbukeli ukuba acabangele umsebenzi ongabonakali wemvubelo, ukushintsha okucashile kwezinga lokushisa nesikhathi okuqondisa ukuziphatha kwayo, kanye nendima yomuntu ekukhuliseni nasekuqondiseni ukukhula kwayo. Ngokwakheka kwaso, ukukhanya, nemininingwane, lesi sithombe sixoxa indaba yokugcinwa—hhayi nje kwezithako, kodwa yolwazi, isiko, nokulinganisela okubucayi okudingekayo ukuze kugcinwe ukuphila kwamagciwane. Kungumfanekiso wokuvutshelwa njengokubili ubuciko kanye nesiyalo, lapho imbiza ngayinye ingagcini nje uketshezi, kodwa amandla.
