Piv txwv li, cov poov xab ua fermentation kom tau txais lub zog los ntawm kev hloov cov suab thaj rau hauv cawv.
Yuav ua li cas rau poov xab ferment?
Feem ntau cov poov xab xav tau ntau cov pa oxygen rau kev loj hlob, yog li los ntawm kev tswj cov pa oxygen, lawv txoj kev loj hlob tuaj yeem kuaj xyuas. Ntxiv nrog rau cov pa oxygen, lawv xav tau ib qho yooj yim substrate xws li qab zib.
