Summary
Marine microalgae extracts from Nannochloropsis oculata, Porphyridium cruentum, and Skeletonema costatum show diverse bioactive compounds. Nannochloropsis oculata extract demonstrated superior antioxidant activity, paving the way for nutraceutical applications.
Area of Science:
- Marine biology
- Phytochemistry
- Nutraceutical science
Background:
- Marine microalgae are rich sources of bioactive compounds.
- Potential applications in nutraceuticals are underexplored.
- Characterization of specific microalgal species is needed.
Purpose of the Study:
- To characterize bioactive compounds in Nannochloropsis oculata, Porphyridium cruentum, and Skeletonema costatum.
- To evaluate the antioxidant potential of these microalgal extracts.
- To identify key metabolites contributing to bioactivity.
Main Methods:
- Extraction and phytochemical analysis of three microalgal species.
- Quantification of chlorophylls, carotenoids, total phenolics, and total flavonoids.
- Assessment of antioxidant activity using DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assays.
- Metabolomic profiling using chromatography and mass spectrometry.
Main Results:
- Nannochloropsis oculata and Skeletonema costatum extracts were rich in chlorophylls and carotenoids.

01:23Red Algae
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
01:25Biofuels
The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
