Potential of Moringa (Moringa oleifera) leaf extract to inhibit the growth of pathogenic bacteria Edwardsiella tarda

Abstract

This study analyzed the antibacterial activity of Moringa oliefera leaf extract against the growth of Edwardsiella tarda bacteria. This study aims to determine the antibacterial activity of Moringa leaf extract (M. oliefera) against the growth of E.tarda bacteria. Inhibition testing is done by diffusion method (disc test). The disc test used five variations of concentration of 75 mg/L, 150 mg/L, 225 mg/L, 300 mg/L, and 375 mg/L on TSA (Tryptone Soya Agar) media and incubated for 2x24 hours. As a positive control, an antibiotic in the form of chloramphenicol was used. (5 mg/L) Moreover, distilled water was used as a negative control.Moringa leaf extract (M. oliefera) contains natural active compounds, bacteriostatic antibacterials, due to decreased bacterial growth after 48 hours of incubation. The highest inhibition diameter of E. tarda was 12.95 mm at a concentration of 375 mg/L after 24 hours incubation and decreased by 11.02 mm after 48 hours incubation. The highest inhibitory effectiveness was at a concentration of 375 mg/L with an effectiveness of 58.8%, while the effectiveness of the decrease was 48.1% after 48 hours of incubation.

EFFECTIVENESS OF Gynura procumbens AGAINST Pangasius sp INFECTED WITH Edwardsiella tarda BACTERIA

“…Recovery process is a process of healing or restoring the systems in the body of the test fish that are problematic after the catfish is injected with the Edwardsiella tarda bacteria (Riyadi et al, 2021). Observations of these clinical symptoms started from the first day after the fish were soaked in the extract of the Connect Nyawa leaf for 30 minutes (day 8) until the 21st day.…”

“…According to Fauziyyah et al, (2021), improved wound conditions and clinical symptoms in catfish due to the content of alkaloid compounds, saponins, flavonoids and tannins contained in the leaves of Gynura procumbens. Gynura procumbens leaves have the potential to be antimicrobial.…”

Increasing fibroblasts and gingival collagen density in periodontitis rats by using cassava leaf extract

“…This reduces the bacterial cell wall's permeability, preventing bacterial cells from receiving nutrients, which in turn prevents bacterial growth or causes the bacteria to die. 46 Vitamin C in cassava leaves can also kill bacteria by changing the pH of the environment to be unsuitable for bacterial growth (pH < 4). Most bacteria usually grow at a pH of 7–7.5 with a minimum pH of 4.5, so vitamin C can inhibit enzyme activity and bacterial metabolism.…”

Potential of Moringa oleifera saponins as a preventive of water pollution from the linear compound alkylbenzene sulfonate (LAS)

“…The benefits of the leaf content of the M.oleifera can be used in chemical compound retention of Linear Alkylbenzene Sulfonate (LAS) in the manufacture of soap (detergent) that can trigger water pollution (Nizioł-ŁUkaszewska et al, 2020;Vergara-Jimenez et al, 2017). In addition, wastewater from soap products material (detergen) can be more environmentally friendly for water quality (rivers, seas, and others (Rachmawati & Suriawati, 2019;Riyadi et al, 2021;Kashyap et al, 2022).…”

“…The potential of Moringa oleifera leaf saponins has a staining role (Rachmawati & Suriawati, 2019;Riyadi et al, 2021) and a foam producer so that there is no accumulation of hazardous waste in the waters (Kashyap et al, 2022) and water biota life is unaffected (Reda et al, 2023). The replacement of soap material with natural materials is expected to prevent water pollution from household waste (Brilhante et al, 2017).…”
