Abstract

Nutrient Content, Active Compound and Antibacterial Activity of Padina australis against Aeromonas hydropilla

Highlights

Macroalgae belong to thallophytes group or plant-like organisms which generally live in coastal areas.[1,2,3] Macroalgae known as seaweed have significant economic value since they can be utilized as vegetables, traditional medicines, organic fertilizers, and livestock fed.[1,3] Even the phytocoloid compounds extracted from macroalgae as agar, carrageenan, and alginate[3], it can be used as raw materials of various industries, such as medicine, cosmetics, food, etc
This study aims to analyze the nutrient content, active compounds, and antibacterial activity of Padina australis against Aeromonas hydropilla
The nutrient content and phytochemical composition of P. australis were examined in this study

Summary

Introduction

Macroalgae belong to thallophytes group or plant-like organisms which generally live in coastal areas.[1,2,3] Macroalgae known as seaweed have significant economic value since they can be utilized as vegetables, traditional medicines, organic fertilizers, and livestock fed.[1,3] Even the phytocoloid compounds extracted from macroalgae as agar, carrageenan, and alginate[3], it can be used as raw materials of various industries, such as medicine, cosmetics, food, etc. P. australis contains 1.05 ± 0.09% protein, 0.58 ± 0.01% fat, 8.78 ± 0.80% carbohydrate, 87.25 ± 0.86% water, 2.34 ± 0.16% ash[7] and minerals as calcium, magnesium, potassium, sodium, copper, zinc, iron[8] that enable to be developed as a food source and livestock fed. Objective: This study aims to analyze the nutrient content, active compounds, and antibacterial activity of Padina australis against Aeromonas hydropilla. Phytochemical analysis showed that P. australis contained phenols, tannin, flavonoid, and steroid. These compound may be responsible for inhibiting A. hydropilla, with an inhibition zone of 10.5 mm for water extract of P. australis and 10 mm for methanol extract P. australis.
