Extracts from 56 southern African seaweeds, from the Divisions Chlorophyta (green), Phaeophyta (brown) and Rhodophyta (red), were screened against 12 bacteria, two yeasts and two moulds for antimicrobial activity. Seaweed extracts were prepared by boiling powdered samples in 80% ethanol. Extracts were pipetted into wells in overlay agar plates seeded with the test microorganisms. Generally, the bacteria were more susceptible to the antimicrobial effects of seaweed extracts than the yeasts and…

Antibacterial activity in marine algae from the coast of Yucatan, Mexico
TLDR
Results generally indicate that the stolon of Caulerpa has the highest antibacterial activity.
Antiplasmodial and antimicrobial activities of South African marine algal extracts
TLDR
It is shown that marine algae not only produce antimicrobial compounds but also may be a source of antimalarial lead compounds.
Potential medicinal value of some South African seaweeds
Antimicrobial and antifouling activities achieved by extracts of seaweeds from Gulf of California, Mexico
TLDR
Six species of common seaweed extracts tested in laboratory assays exhibited significant antifouling activity with minimum inhibitory concentration between 1-10 µg ml-1 against marine microalgae Rhodosorus magnei, Neorhodella cyanea and Prymnesium calathiferum.
Differential Antibacterial Activity of Extracts from Selected Southern African Macroalgal Thalli
TLDR
Eight southern African seaweeds, previously shown to exhibit antibacterial activity, were analysed to assess the distribution of antib bacterial activity in extracts from selected portions of their thalli, showing a uniform distribution of antimicrobial activity throughout its thallus against all test bacteria.
ANTIBACTERIAL ACTIVITY OF BROWN SEAWEED PADINA TETRASTROMATICA HAUCK FROM SOUTH EAST COAST OF TAMIL NADU, INDIA.
TLDR
The overall antibacterial activity assessed indicates the presence of active constituents in the extracts and the seaweed can be used in pharmaceutical industry.
In vitro antimicrobial activity of three medicinal plants of Ethiopia against some selected bacterial isolates
TLDR
Ethanol extracts of Moringa stenopetala, Thymus serrulatus, and Terminalia brownii showed promising antimicrobial activity justifying their usage in traditional medicine.
In Vitro Antibacterial Activity of Extracts of Selected Marine Algae and Mangroves against Fish Pathogens
TLDR
In vitro screening of organic solvent extracts of three marine algae and five mangroves showed species specific activity in inhibiting the growth of six virulent strains of bacteria pathogenic to fish.
Antibacterial Activity and Qualitative Phytochemical Analysis of Selected Seaweeds from Gulf of Mannar Region
TLDR
The phytochemical analysis of the aqueous extracts of some commonly occurring green seaweed Cladophora glomerata and Ulva reticulata revealed the presence of Carbohydrates, Alkaloids, Steroids, Tannin & Phenols, Saponins, Fixed oils & Fats, Gums & Mucillage, Proteins, Flavonoids and Volatile oils in varying concentration.
In vitro antimicrobial activity of solvent extracts of marine brown alga, Hydroclathrus clathratus (C. Agardh) M. Howe from Gulf of Mannar. -
TLDR
Different solvent extracts of seaweeds used in the present study have shown significant bacterial and fungal action and offers opportunities for producing new types of bioactive compounds, however, the mechanism of inhibition and stability of the extracts still are not clear.
