Lactic acid Bacteria was CaCo3 analysis and band with lactic acid produce from bacteria . calcium lactate was end production

only The bacteria analysis of CaCo3 was give clear zone .

Indah Nfitria

thankyou Mr. @Alaa Kareem Niamah . it will be very usefull for me :)

Nihir P Shah

Lactic acid bacteria produces lactic acid as an end product of fermentation/growth in any suitable medium. When you add CaCO3 in media, lactate react with it and form Ca-lactate and so, you get clear area/zone surrounded the colonies of lactic acid bacteria.
