Abstract

Lactobacillus sp F213 (LbF213) is a lactic acid bacterium isolated from a healthy baby feces, which has been proven as a probiotic bacteria because it is resistant to low pH, bile salts, digestive enzymes, able to aggregate, attach and colonize the intestine, and interact against E. coli. This study aims to determine the viability of probiotic bacteria LbF213 on various juices during storage. The fruits used in this study were soursop, tamarillo, orange, and pomello. This study used a descriptive comparative method experimental design. The variables observed were total LAB, total sugar, total acid, and pH tested every 3 days from the 1st day to the 12th day in the cold storage. The results showed that the total LAB of LbF213 in tamarillo juice during 12 days of storage tend to be constant compared to soursop, orange, and grapefruit juice whereas total LAB, from the first day of storage was 1.37x106 CFU/ml to 12th day of storage was 1.81x106 CFU / ml with a total sugar value 3.13%, total acid value 1.22%, and pH 3.95.

Abstract

This study aims to determine the effect of storage duration of curry leaves (Murraya koenigii (L) Spreng) on the total phenols and antibacterial activity of Salmonella enteritidis ATCC 13067, and the appropriate storage duration of curry leaves to produce the highest total phenols and the antibacterial activity. This study used a Completely Randomized Design (CRD) with treatment duration of storage that is 0, 3, 6, 9, and 12 days. The treatment was repeated 3 times to produced 15 experimental units. Data were analyzed by analysis of variance (ANOVA), if each treatment had a difference then preceded with the Duncan Test. The observed variables were total phenols and antibaterial activity S. enteritidis ATCC 13067. Qualitative testing showed that curry leaves extract positively containing phenols. The storage duration of curry leaves significantly affected the total phenols and antibaterial activity of S. enteritidis ATCC 13067. The best treatment was produced in the treatment without storage with the highest total phenols was 3,598.17 mg / 100g and the highest antibaterial activity power was -1,321 log cycles or 95.16% mortality bacteria.

Abstract

Lactic Acid Bacteria must pass several tests to increase their potential as probiotics, one of which is to test their resistance to antibiotics. This study was aimed to determine the resistance of the indigenous lactic acid bacteria (LAB) isolates from kombucha and dadih against amoxicillin, tetracycline, and chloramphenicol, and measure their levels of resistance against amoxicillin, tetracycline, and chloramphenicol. There were 2 treatments that are done in this study such as the type of isolates, and the type of antibiotics used. LAB growth inhibition zones against antibiotics were tested using disk diffusion method and analyzed using quantitative descriptive method. Based on the result of this study, it was found that L. plantarum RN9, L. plantarum I MK2, and L. plantarum I ML7 had an intermediate resistance against amoxicillin, while all the isolates tested are resistant to tetracycline and chloramphenicol. L. pentosus MS21 had the most resistance against amoxicillin. L. plantarum I MK2 had the most resistance against tetracycline. and L. plantarum I ML7 had the most resistance against chloramphenicol.

Abstract

The aim of this research was to determine the concentration of phenol compounds and antifungal activity of torch ginger (Etlingera elatior) on Aspergillus flavus FNCC 6109. This research was a completely randomized design with 10 concentrations of shoot, flower, and fruit extract which were 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%. The data were analyzed with variance analysis then followed by Duncan Multiple Range Test (DMRT). Analysis were repeated 2 times resulting in 20 experimental units. Result showed that each concentration of shoot, flower, and fruit extract had significantly effect (P<0,05) in inhibition of Aspergillus flavus FNCC 6109. Shoot, flower, and fruit extract of torch ginger contained phenol compounds of 154,56 mgGAE/g, 127,22 mgGAE/g, and 261,52 mgGAE/g. The best antifungal activity for shoot extract of torch ginger was at 70% concentration with a diameter inhibition of 7,9 mm category medium, for flower extract of torch ginger was at 90% concentration with a diameter inhibition of 5,65 mm category medium, and for fruit extract of torch ginger was at 80% concentration with a diameter inhibition of 13,75 mm category strong. Fruit extract of torch ginger had the highest phenol compound which could inhibit Aspergillus flavus FNCC 6109. Keywords : phenol, torch ginger, antifungal, Aspergillus flavus.
