Antibacterial property of algal pigment extracts (chlorophyll, fucoxanthin, and phycoerythrin) against Escherichia coli and Staphylococcus aureus
The rapid emergence of drug resistance among various pathogenic bacteria stresses the need for new compounds used in the production of antibiotics. In the present study, the seaweed samples were collected along the coastal areas of Calatagan, Batangas. The algal pigments were isolated using pure...

| Summary: | The rapid emergence of drug resistance among various pathogenic bacteria
stresses the need for new compounds used in the production of antibiotics. In the
present study, the seaweed samples were collected along the coastal areas of
Calatagan, Batangas. The algal pigments were isolated using pure acetone as the
solvent. The pigment extracts from three different seaweeds species were
extracted and were tested for their antibacterial activities against two test
organisms which were: Staphylococcus aureus (SA), and Escherichia coli (EC).
The algal pigments were evaluated using Kirby – Bauer method to determine their
inhibitory activity. The results indicated a minimal spectrum of inhibitory activity
from all of the samples, exhibiting different measurements of zone of inhibition.
From the susceptibility index table (See Appendix C), resistances to the effects of
the pigment extracts were observed from the test bacteria. |
