Anti-Fungal Efficacy and Secondary Metabolite Analysis of the Methanolic Extract from Colpomenia peregrina towards Opportunistic Fungal Pathogens

The present study illustrates the antifungal efficacy of methanolic extract from marine brown seaweed Colopomenia peregrina gathered from Leepuram coast, South India, towards opportunistic fungal pathogens comprising dermatophytes, non-dermatophytes, and yeasts. The opportunistic fungal pathogens used in the study are Aspergillus flavus (ATCC 27692), Aspergillus fumigatus (ATCC 19673), Microsporum gypseum (ATCC 24102), Cryptococcus neoformans (ATCC 14116), and Candida albicans (ATCC14053) which are commonly responsible for nosocomial infections. The NMR analysis revealed the presence of various chemical shifts showing the presence of protons containing Hydroxyl, Methoxy, Methyl groups, and –COO-CH2 groups. The presence of phytochemicals from the extract of seaweed confirmed the nutritional profile. The results revealed greater efficacy of methanolic extract towards Aspergillus fumigatus, Microsporum gypseum, Cryptococcus neoformans, and lower activity with Aspergillus flavus and Candida albicans compared with the standard anti-fungal fluconazole.
