Isithombe: Swirling Yeast Culture in Glass Flask

Isithombe sibonisa ukusondelana okumangazayo kwesikhashana sokwenza isiphuzo sesayensi, esigxile ebhodleleni lengilazi elihlanzekile le-Erlenmeyer eligcwele isiko lemvubelo enyakazayo. I-flask, eyenziwe ngengilazi ye-borosilicate yezinga laselabhorethri, ime yinde futhi i-conic inentamo ewumngcingo nesisekelo esibanzi, egxishwe ngezimpawu zokulinganisa ezimhlophe ngamamililitha. Lezi zimpawu—“1000 APPROX,” “900,” “800,” kanye “700”—zibonisa umthamo woketshezi olusagolide ngaphakathi, olufinyelela ngaphansi nje komugqa ongu-900 ml.

Uketshezi ngokwalo luyigolide eliqhakazile, elicebile ngokufiphala nokuthungwa. Ibhamuza kancane, nongqimba olunamagwebu lwegwebu kwakheka phezulu kanye namabhamuza amancane aphuma esisekelweni. Ukunyakaza okuzungezayo ngaphakathi kweflaski kudala i-vortex ebonakalayo, kudonsela iso phakathi nendawo lapho amangqamuzana imvubelo ebila khona. Ukunyakaza okuguquguqukayo koketshezi kusikisela inqubo ephilayo—eyokuguqulwa, amandla, nokunemba kwamagciwane.

Ukukhanyisa ngemuva kudlala indima ebalulekile emkhathini wesithombe. Umthombo wokukhanya ofudumele, othambile ngemva kweflaski usakaza i-halo esagolide emakhoneni ayo, ukhanyisa uketshezi olusuka ngaphakathi futhi udale ukuhlukahluka kwamathoni afudumele ngemuva. Ukushintsha kokukhanya kusuka ku-amber ekhanyayo phezulu kwesokunxele kuya ethusi elijulile, elithobe kakhulu kuye ngezansi kwesokudla, okuthuthukisa umuzwa wokujula nokufudumala. Indawo yengilazi yeflask ibonakalisa lokhu kukhanya ngokucashile, ngokugqama okufiphele eduze konqenqema nesisekelo sayo.

I-flask ihlezi endaweni emnyama, e-matte—okungenzeka ibhentshi lelebhu noma isiteshi sokuphisa—enokuthungwa okubonakalayo nemihuzuko efiphele ebonisa ukusetshenziswa okuphindaphindiwe. Ukubonakala okuthambile kwesisekelo seflask kubonakala phezulu, kugxilisa ukwakheka futhi kwengeza okwangempela. Ingemuva lihlala lifiphele kancane, liqinisekisa ukuthi konke ukunaka kudonswa kufulaski nokuqukethwe kwayo.

Lesi sithombe sivusa umuzwa wokunemba kwesayensi nokunakekelwa kobuciko. Ithwebula ukuphambana kwebhayoloji nokuphisa, lapho ukusebenza kwemvubelo kuqashwe ngokucophelela ukuze kuqinisekiswe ukuvutshelwa okufanele. Amasiko anyakazayo, igwebu elibenyezelayo, nokukhanya okufudumele ndawonye kudlulisa umzuzwana wokuthula—lapho ukuqaphela, isikhathi, nobuchwepheshe buhlangana khona ukuze kulokhele ukunambitheka kwekusasa kotshwala.
