CALCIUM LACTATE INFLUENCE ON SOME NON-PATHOGENIC MICROORGANISMS

Octavian BASTON, Octavian BARNA

Abstract

After calcium lactate was produced by chemical reaction between lactic acid and calcium carbonate  from  eggshells,  it  was tested  on  some  non-pathogenic  microorganisms.  The influence  of calcium lactate powder on non-pathogenic microorganisms varied as group and species. All the non-pathogenic bacteria growth was inhibited by calcium lactate, the inhibition diameter ranged between 1.92 ±  0.23  to  2.35 ±  0.12  cm.  Among  yeasts  only Candida  mycoderma  and  Pichia  sp.  growth  was inhibited. Calcium lactate showed no influence on the studied moulds: Aspergillus niger, Penicillium
sp.  and  Rhizopus  sp.  Calcium  lactate  is  a  substance  that  has  an  inhibition  effect  on  some  non-pathogenic micoorganisms.  It  can  be  used  alone,  without  being  combined  with  other  substances, having an acidifying effect on the microorganism nutritive media.
