Isithombe: Imvubelo Isiko Elingenampilo Liyaphenywa

Lesi sithombe sithwebula isikhashana sokuphuthuma okuthulile ngaphakathi kwelabhorethri ekhanyiswe kalufifi, lapho amathuluzi esayensi ehlelwa khona ukuze abhekane nenkinga yebhayoloji ephikwayo. Isehlakalo sicwile emkhathini, nokukhanya okuguquguqukayo, okuphelelwe amandla okwenza izithunzi ezinde endaweni yokusebenza, okugcizelela ubunzima bophenyo oluqhubekayo. Phakathi nendawo yokubunjwa, isitsha se-petri sihlezi ebhentshini lebhu, okuqukethwe kwayo kukhanyiswa i-beam egxilile yokukhanya. Ngaphakathi, isiko le-yeast elingenampilo lizungeza echibini elingashoni le-nutrient medium. Amaseli abonakala ecindezelekile—akhiwe ngendlela engafanele, anombala ongalingani, futhi ahlangene ngamaphethini aguquguqukayo. Ezinye zibonakala ziqunjelwe noma ziqhume, ezinye zifiphele futhi zishintshashintsha, okubonisa ukuwohloka noma ukungcoliswa kwamangqamuzana. Isitsha ngokwaso sihlanzekile, kodwa isiphithiphithi sebhayoloji esikuso sikhomba udaba olujulile, oludinga ukunakwa ngokushesha.

Ngalé nje kwesitsha se-petri, isibonakhulu sibonakala, amalensi aso aqeqeshwe esilayidini embula isiko le-yeast efanayo enezinkinga ngemininingwane ekhulisiwe. Ngaphansi kokucutshungulwa kwe-microscope, izinto ezingavamile ziba sobala nakakhulu. Amaseli amise okweqanda, ngokuvamile afanayo futhi anempilo kumasiko anempilo, manje abonisa izimpawu zokuxineka: amakhonsathi angajwayelekile, ingaphakathi eliyimbumbulu, kanye namabala angahambisani. Lezi zimpawu ezibonakalayo ziphakamisa ukuwohloka kobuqotho beselula, okungenzeka ngenxa yezicindezelo zemvelo, ukuntula izakhi, noma ukuba khona kwamagciwane ahlaselayo. Ubukhona be-microscope abugcini nje—buyisango lokuxilonga, ithuluzi lapho okungabonakali kwaziwa khona.

Indawo yokusebenza ezungezile iqinisa umqondo wokubuza okugxilile. Kusabalele ebhentshini amaflask, ama-pipette, namabhodlela ezinto ezisetshenziswayo, ngalinye liyithuluzi elinamandla emzamweni wokuhlukanisa inkinga. Uhlelo luhlelekile kodwa luhlala ngaphakathi, okuphakamisa ilebhu esetshenziswayo, lapho ukuhlola nokubheka kuqhubeka khona. Ngemuva, amashalofu afakwe amabhuku ezithenjwa, amanothi abhalwe ngesandla, namashidi edatha aphrintiwe engeza isisindo sobuhlakani endaweni yesehlakalo. Lezi zinto azihlobisi—ziwulwazi oluqoqiwe lophenyo lwangaphambilini, manje okuxhunyanwa nalo ukuze kuzwakale ukudideka kwamanje. Ibhodi noma ibhodi elimhlophe, elibonakala kancane, linezibalo ezibhalwe phansi namashadi agelezayo, mhlawumbe enze imephu ecatshangelwayo noma alandelele ukuqhubeka kokwehla kweyeast.

Ukukhanyisa kudlala indima ebalulekile ekulolongeni ithoni engokomzwelo yesithombe. Akukhona ukukhanya okukhanyayo, okubulalayo kwelebhu evamile, kodwa kunalokho ukukhanya kwethiyetha okwengeziwe, okuqondisayo okuhlukanisa izici ezibalulekile futhi kujulise ithunzi. Lokhu kukhetha kudala umuzwa wedrama nokuphuthuma, njengokungathi ilebhu isiphenduke isiteji semfihlakalo yesayensi. Umehluko phakathi kokukhanya nobumnyama ubonisa umehluko phakathi kolwazi nokungaqiniseki, phakathi kwemingcele eyaziwayo ye-yeast biology kanye nokuchezuka okungalindelekile okwenzeka manje.

Sekukonke, isithombe sidlulisa ukulandisa kokuxazulula inkinga kwesayensi, lapho ukubhekwa, ukuhlaziya, kanye nengqondo kuhlangana ukuze kubhekwane nenkinga yezinto eziphilayo. Kungumfanekiso wesikhashana lapho ukuziphatha okujwayelekile kwemvubelo kungahambanga kahle, futhi abacwaningi kufanele bathembele kumathuluzi abo, ukuqeqeshwa kwabo, kanye nomuzwa wabo wemvelo ukuze baveze imbangela. Ngokwakheka kwaso, ukukhanya, kanye nemininingwane, isithombe simema umbukeli enhliziyweni yophenyo, sinikeza amazwibela omsebenzi ocophelelayo futhi ngokuvamile othinta imizwa osekela ucwaningo lwe-microbiological. Kuyisikhumbuzo sokuthi isayensi ayigcini nje ngokuphathelene nezimpendulo-imayelana nokuphishekela ukuqonda, ikakhulukazi uma idatha ingahambisani nokulindelwe.
