Analysis of Antimicrobial Activity of Carrageenan Extracted from Kappaphycus Alvarezii

The abuse of synthetic antibiotics is one the leading causes emergence antibiotic-resistant microorganisms that have become primary health concern. To overcome this resistance and counteract all side effects drugs, attention was diverted towards natural resources for developing antimicrobial substances. This study tests effect carrageenan isolated from Kappaphycus alvarezii on pathogenic bacteria. Carrageenan a bioactive compound extracted red algae. K. using hot water extraction. property tested Minimum Inhibitory Concentration bacterial cell growth rate. Moreover, commercial antibacterial hand wash anti-acne toner were used as comparative agents. Firstly, series concentrations used, 25 µg/mL to 10 mg/mL. results showed no activity ethanol toward strains in study, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa Staphylococcus aureus. However, exhibited growth-boosting over used. Thus, further studies can be carried out different extract methods ensure anti-microbial compounds during
