Abstract

Abstract Studies were done to improve the stability and viability of probiotic lactic acid bacteria Pediococcus pentosaceus by supplemeting cysteine hydrochloride (Cys Hcl) and ascorbic acid (AA) as oxygen scavengers at different concentrations. The adjuvants were supplemented to the culture in MRS broth stored at 28°C and 18°C for 12 days keeping in mind the milk products like biocurd (patent no: NF482005) prepared with the same culture till the laboratory to be used for a period of 10 days. It was found that Cys HCI and AA at a concentration(iOIl of- JOOmg/L were the best 10 imprm'c the stability and viability of probiotic lactic acid bacteria. During the study, the decrease if the pH and all increase ill the acidity in control with lower growth were attributed to autolysis as visualized by scanning electron microscopy. Release of proteins was also observed. The increase ill growth in the supplemented samples can be correlated to the decrease in the 02 content thus improving the stability and viability by four logs as compared to the control.
