“…The existence of fatty acid compounds, flavonoids and polyphenolic compounds could be linked to the antimicrobial activity of Spirulina (Martelli et al ., 2020; Sowmya et al ., 2021). Antimicrobial compounds like caffeic and coumaric acids, bis (2‐ethylhexyl) phthalate, 1,2‐benzendicarboxilic acid, bis (2‐ethylhexyl) ester, benzophenone, dinitrobenzoate, propanediamine, isoquinoline, piperidin, oxazolidin, pyrrolidine and dioctylamine were also reported for Spirulina (Ama Moor et al ., 2016; Alshuniaber et al ., 2021; Özogul et al ., 2021; Hidhayati et al ., 2022). Similar to these studies, unfermented and fermented Spirulina contained significant levels of heptadecane, propenamide, 1,1‐diethoxyethane, tert‐butyldimethylsilyl 2,2,3,3,3‐pentafluoropropanoate and other compounds that may be responsible for the antimicrobial properties of Spirulina .…”
