Red Algae

Red 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...

Microbial Bioremediation of Hydrocarbons

Microbial Bioremediation of Hydrocarbons

Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...

Background:

Brown seaweeds are recognized for their health benefits.
Subcritical water extraction (SWE) is an effective method for isolating bioactive compounds.
Understanding the physiochemical and bioactive properties of seaweed is crucial for application development.

Purpose of the Study:

To characterize the bioactive properties of Sargassum thunbergii, Undaria pinnatifida, and Saccharina japonica.
To evaluate antioxidant, antihypertensive, and α-glucosidase inhibitory activities of seaweed hydrolysates.
To assess the antibacterial activity of seaweed extracts against foodborne pathogens.

Main Methods:

Subcritical water extraction (SWE) was used to obtain hydrolysates from three brown seaweed species.
Analysis of total phlorotannin, total sugar, and reducing sugar content.
Assays for antioxidant activity (ABTS+, DPPH, FRAP), antihypertensive effects, and α-glucosidase inhibition.
Evaluation of antibacterial activity against foodborne pathogens.

Main Results:

Sargassum thunbergii hydrolysates exhibited high phlorotannin and sugar content.
Saccharina japonica hydrolysates showed potent ABTS+ and DPPH antioxidant activities.
Sargassum thunbergii hydrolysates demonstrated high FRAP activity.
Seaweed extracts displayed significant antihypertensive and α-glucosidase inhibitory effects.
Extracts were effective against foodborne pathogens.

Conclusions:

Brown seaweed extracts possess diverse bioactive properties, including antioxidant, antihypertensive, and antimicrobial activities.
SWE is a viable method for extracting valuable compounds from Sargassum thunbergii, Undaria pinnatifida, and Saccharina japonica.
These findings support the potential use of brown seaweed extracts in the food, pharmaceutical, and cosmetic industries.
