Hoto: Girman Saccharomyces Cerevisiae Yisti

Wannan hoton yana ba da kusancin sel yisti na Saccharomyces cerevisiae, wanda aka kama a cikin ɗan lokaci na tsaftataccen haske da ƙarfin ilimin halitta. Abun da ke ciki yana da kusanci kuma mai zurfi, yana jawo mai kallo zuwa cikin ƙananan ƙananan duniya inda fermentation ya fara. Kowane tantanin halitta ana fitar da shi cikin daki-daki-plum, mai siffa mai siffar kwai, da ɗan haske, samansu yana kyalli da danshi. Digon ruwan da ke manne da sel yana kara girman su, yana mai da haske mai ɗumi da zinariya wanda ke wanke wurin gaba ɗaya.
