Antimicrobial activities of stearidonic and gamma-linolenic acids from the green seaweed Enteromorpha linza against several oral pathogenic bacteria

Botanical Studies

Table 3 Minimum inhibitory concentration (MIC) values of commercial stearidonic acid (SA) and gamma-linolenic acid (GLA), and positive controls (triclosan and chlorhexidine) against several oral pathogens

Oral pathogens	MIC value (μg/mL)
	Positive controls		SA	GLA
	Triclosan	Chlorhexidine
Aggregatibacter actinomycetemcomitans	ND	4.88	312.50	78.12
Candida albicans	312.50	4.88	312.50	78.12
Fusobacterium nucleatum subsp. vincenti	4.88	2.44	39.06	9.76
Streptococcus mutans	ND	9.76	1,250	625
Prevotella intermedia	1,250	1.22	39.06	39.06
Porphyromonas gingivalis	78.12	1.22	9.76	9.76

All measurements were performed in triplicate, and are the average of three experiments; ND not determined.
