Isithombe: Ukuqhathanisa ne-Beer Yeast Strains

Isithombe sibonisa indawo yaselabhorethri ehlelwe kahle eklanyelwe ukugqamisa ukuqhathaniswa kwezinhlobo ezahlukene zemvubelo kabhiya endaweni ehlanzekile, elawulwayo. Ukwakheka kukuma-landscape futhi kunomqondo oqinile wokujula, ukusuka kuzinto ezinemininingwane ecijile ngaphambili ukuya ezakhiweni ezifiphele kancane ngemuva. Isimo sesimo sezulu singesinye sokunemba kwesayensi nokugxila kokuhlaziya, okugcizelela izimfanelo ezincane kakhulu nezamakhemikhali ezinto eziphilayo zokukhiqiza imvubelo ngaphakathi komongo wokukhiqizwa kukabhiya.

Ngaphambili, amabhika ayingilazi amabili aboniswe ngokugqamile phezu kwebhentshi elimhlophe qwa. Ibhika ngalinye ligcwaliswa ngendlela yoketshezi ehlukile emele amasiko amabili ahlukene emvubelo. Ibhika elingakwesokunxele liqukethe uketshezi olusagolide oluphaphathekile olunekhwalithi elufifi, engacacile, ephakamisa ukumiswa okusebenzayo kwamaseli yeast. Amakholoni amancane, ayindilinga yemvubelo noma amaqoqo abonakala entanta ngaphakathi koketshezi, anikezwe ngokucaca kwesitayela esikhulu esigqamisa isakhiwo sawo esiyindilinga, esishintshashintsha kancane. Ibhekha elingakwesokudla liphethe uketshezi olunhlaka olujulile olunombala ocebile, futhi ngaphakathi kwalo, amaseli amaningi ama-yeast amakhudlwana noma amakoloni amisiwe. Lezi zibonakala ziminyene kakhulu futhi zikhanya kancane kunalezo ezikubhika ongakwesokunxele, okubonisa umehluko ku-morphology yamaseli noma ukuminyana phakathi kwezinhlobo. Womabili amabhikha amakwe ngemigqa yokulinganisa yemethrikhi enembayo emhlophe, ebonisa ama-milliliter gradations, okuqinisa ithoni yesayensi neyokuhlola yendawo yesehlakalo.

Isibonakhulu esihlanganisiwe sima kwesokunxele samabhika, amalensi ayo ensimbi acwebezela kancane ngaphansi kokukhanya okulawulwayo. Isiteji se-microscope asigxilile kancane, kodwa ukuba khona kwaso kugcizelela umqondo wokuthi lawa masiko emvubelo acutshungulwa kahle futhi ahlaziywe ezingeni lamaselula. Imiphongolo yelensi ibamba ukukhanya okuvela ezilambuni zaselabhorethri, engeza okuvelele okucashile okugqamayo ngokumelene nezindawo ze-matte zomzimba we-microscope. Ukubekwa kwe-microscope emaphethelweni ohlaka kusho ukuthi isanda kusetshenziselwa ukuhlola amasampula kumabhikha, kuhlanganisa izinto ezibukwayo zibe ukulandisa kocwaningo oluqhubekayo.

Emhlabathini ophakathi, umugqa wamabhodlela kabhiya ayingilazi amane ansundu ume uqondile emgqeni ococekile. Ibhodlela ngalinye liphethe ilebula ehlukile ekhomba uhlobo oluhlukile lwemvubelo noma isitayela sikabhiya. Ukusuka kwesobunxele kuye kwesokudla, amalebula afundeka kanje: “Lager Strain”, “Belgian Strain”, “Bottle Strain”, kanye “Ale Strain.” Lawa malebula abhalwe ngendlela elula, egqamile yokubhala evusa ubuhle besitolo sotshwala kuyilapho ehlala ehlanzekile futhi engokwesayensi esethulweni. Amabhodlela ahlukaniswe ngokulinganayo futhi aqondaniswe ngokulinganayo, asebenza njengezethulo ezingokomfanekiso zemikhiqizo eqediwe ewumphumela wezimpawu zokuvutshelwa kohlobo ngalunye lwe-yeast. Amabhodlela engilazi abonisa ngobuqili ukukhanya okuzungezile, futhi umbala wawo onsundu ngokusa-amber uhluke ngokuvumelana namathoni alula oketshezi olukumabhokwe.

Ngemuva, indawo yaselabhorethri ibuyela ekufiphaleni okuthambile, okudala ukujula ngaphandle kokuphazamisa ezifundweni eziyinhloko. Izingcezu ezihlukahlukene zezingilazi zaselabhorethri—njengamaflask, amabhika, namasilinda aseqedile—zingabonakala zihlelwe emashalofini nasezindlini zokubala. Izikhathi eziningi azinambala noma zifiphele ngokufiphele, zibamba okuvelele okusabalele okukhomba isimo esiyinyumba nesihlelekile sendawo yokusebenza. Isilungiselelo esifiphaziwe siphakamisa indawo yelebhu ehlonyiswe ngokugcwele, yesimanje kuyilapho kuqinisekiswa ukuthi ukunaka kombukeli kuhlala kugxile kumasampula emvubelo namabhodlela kabhiya.

Ukukhanyisa kuthambile, kuyalingana, futhi kuhlakazeke kahle, kuqeda izithunzi ezinokhahlo futhi kugcizelele ukucaca nokuhlanzeka kwe-glassware, uketshezi, kanye nemishini. Lokhu kukhethwa kokukhanyisa kuthuthukisa imininingwane yesitayela esikhulu samaseli eyeast kuma-beakers, kuwenze abe khona okuthambile kwezinhlangothi ezintathu. Iphalethi yombala iyonke iyavinjelwa futhi ihlangene, ibuswa abamhlophe abangathathi hlangothi kanye nezimpunga eziphawulwe ama-amber afudumele nama-golden hues oketshezi namabhodlela. Umkhathi owumphumela uzwakala uzolile, umtholampilo, futhi ugxile kakhulu, ubonisa indlela yokuhlaziya ethathwa ososayensi lapho behlola ukusebenza kwemvubelo yokuphisa.
