Abstract. Rizal S, Suharyono, Nurainy F, Amela JR. 2020. The effects of low-temperature storage on the viability of Lactobacillus casei and the stability of antibacterial activity in green grass jelly synbiotic drinks. Biodiversitas 21: 3826-3831. Synbiotic drinks from green grass jelly have shown antibacterial activity against pathogenic bacteria. These are usually stored at low temperatures to maintain their characteristics. The aim of this study was to determine the effect of storage at low temperature of 10°C on the viability of lactic acid bacteria (Lactobacillus casei) and the stability of the antibacterial activity in synbiotic drinks made of green grass jelly. Antibacterial activity of green grass jelly synbiotic drink was conducted against pathogenic bacteria (Staphylococcus aureus, Salmonella sp., Bacillus cereus, and Escherichia coli). The products were stored for 28 days at 10°C temperature. Observations on the antibacterial activity, pH value, total acid, and total lactic acid bacteria were carried out every 7 days. Antibacterial activity was evaluated using agar well diffusion method. The results showed that storage at low temperature (10 ± 2°C) for 28 days decreased the antibacterial activity and pH value but sharply increased total lactic acid bacteria (at 0 to 7 days of storage) in green grass jelly synbiotic drinks. Salmonella sp. showed the highest inhibition caused by the antibacterial agents in green grass jelly synbiotic drinks while the lowest inhibition was found on Staphylococcus aureus. During storage at low temperature, green grass jelly synbiotic drinks had a total of lactic acid bacteria that ranged from 9.51 to 10.10 (Log CFU/mL) or equal to 3.24x109-1.26x1010 CFU/mL; a total of lactic acid that ranged from 0.48% to 0.87%; and pH values that ranged from 3.78 to 4.08.

The Difference

Introduction: Endodontic treatment failure can be caused by the bacterium E. faecalis, which has a prevalence of up to 90%. E. faecalis is difficult to eradicate because it forms a biofilm to defend itself against antibacterial agents. Lime leaves are one of the many herbal products available in Indonesia (Citrus hystrix DC). Lime leaf extracts include antibacterial components such as essential oils, phenolics, alkaloids, saponins, and tannins. The purpose of this study was to investigate the antibacterial activity of lime leaf extract against E. faecalis bacterium. Material and Methods:The agar diffusion technique was used for four experimental groups, using lime leaf extract at 4% (group 1), 8% (group 2), and 16% (group 3) as the negative control. Each group was repeated six times on Muller Hinton Agar (MHA) medium with a paper disc, and the diameter of the inhibitory zone was measured with a caliper. Results and Discussions: The results revealed that a 4 % concentration of lime leaf extract had an average inhibition zone diameter of 7.31 mm, an 8 % concentration had an average inhibition zone diameter of 8.59 mm, and a 16 % concentration had an average inhibition zone diameter of 11.41 mm. The difference in the inhibition zone was statistically significant (p= 0,000) evaluated using the one-way ANOVA. Conclusion: It can be concluded that lime leaf extract is antibacterial potential against E. faecalis bacteria in the endodontic treatment.

1. Silver nitrate or sodium merthiolate can be used for the sterilization of suspensions of B. typhosus and neither have any immediate destructive effect on the Vi, O or H antigens.2. Two methods of employing silver nitrate as a sterilizing agent are described.3. Physiological saline solution with silver nitrate added is bactericidal for B. typhosus and the staphylococcus but has no inhibitory action on the growth of moulds.4. Vaccines sterilized and preserved with silver nitrate after storage for 6 months at 7° C. were found to have retained their Vi antibody stimulating properties.5. A vaccine sterilized and preserved with “katadyn” after storage for 18 months at 7° C. still contained some Vi antigen and was superior as an immunogenic agent to a freshly prepared heat-killed-phenolized vaccine.6. It would appear that the stability of Vi antigen is increased by the addition of silver within certain limits, but this effect is only obtained if low temperature storage conditions are maintained.7. A vaccine sterilized and preserved with sodium merthiolate after 6 months' storage at 7°C. failed to stimulate any Vi antibody in the rabbit.
