Abstract

Eichhornia crassipes and Pistia stratiotes are weeds that often pollute water areas. These two contain various active compounds that act as antimicrobials, which have the potential as disinfection agents to prevent the transmission of pathogenic bacteria and fungi. An antimicrobial substance is said to be effective as a good disinfectant if it has a phenol coefficient value equal to or more than the 5% phenol comparison substance. The aim of this research was to test the effectiveness of a combination of Eichhornia crassipes and Pistia stratiotes extracts as a disinfection candidate through the phenol coefficient test. This in vitro experimental study was carried out using a dilution technique. The combination treatment of Eichhornia crassipes and Pistia stratiotes extracts and 5% phenol was tested against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi and also Candida albicans yeast. Observations on the test media suspension tubes that were clear or did not show the growth of the test microbes for a period of 5, 10, and 15 minutes. The phenol coefficient value of the combination treatment of Eichhornia crassipes and Pistia stratiotes extracts was ≥1 with 5% phenol as comparison. Higher coefficient values were obtained for Staphylococcus aureus, equivalent values of 5% phenol were found for E.coli, P.aeruginosa, and C.albicans; whereas in S.typhi the value is <1. The combination treatment of E.crassipes and P.stratiotes extracts resulted in a phenol coefficient value equivalent to that of 5% phenol comparator, for several tested bacteria and yeasts. So it has effectiveness as a preparation for disinfection. The combination of Eichhornia crassipes and Pistia stratiotes extracts has antimicrobial effectiveness and can be developed as an alternative disinfection candidate.

Abstract

Background:  Eichornia crassipes and Pistia stratoites are aquatic weeds that contain various antimicrobial compounds and have the potential to disinfectants. Objective: This study aims to analyze the antimicrobial activity of extract of Eichornia crassipes and Pistia stratoites as In Vitro disinfection agentsMethods: This in vitro experimental study tested E.crassipes and P.statoites extracts in combined (EC+PS)  forms against several species of bacteria and Candida albicans. The testing of antimicrobial activity using the diffusion method and effectiveness as a disinfectant were tested through the phenol coefficient test. Results: The results of the data analysis of the EC+PS 25%-100% (ratio 1:1) treatment using the ANOVA test and Duncan's posthoc (significance 95%), obtained different inhibition zones for gram-positive, gram-negative bacteria, and C.albicans; EC100%+PS100 extract produced the widest inhibition zone. The inhibitory power of EC+PS extracts ranged from moderate to strong (> 5 mm - > 20 mm). In the phenol coefficient test using a dilution of 1:20-1:250, a good coefficient value (> 1) was obtained from the EC+PS extract treatment and the disinfectant control for all test organisms.  Conclusion: E.crassipes and P.stratoites extracts can produce antimicrobial activity with a good phenol coefficient value, which makes their combination a natural disinfectant.
