This study aimed to analyze minerals (Ca, Mg, Fe, Zn, Mn and Cu) heavy metals (Pb Cd) content of seaweeds collected from coastal waters Bangladesh using Atomic Absorption Spectrophotometer (AAS). Eight wild species in three phyla viz. Rhodophyta (Hypnea sp.), Chlorophyta (Enteromorphasp.),and Phaeophyta (Sargassumsp.,Hydroclathrusclathratus, Padinapavonica, Colpomeniasinuosa, Petalonia fascia D...

Different solvent extracts of a red algae, Hypnea flagelliformis, and two brown algae, Cystoseira myrica and Sargassum boveanum, which were collected from the Persian Gulf coast were subjected to different bioassays, including: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (TLC)-bioautography, agar disc dif...

This study evaluated the influence of the shoot density of the shoal grass Halodule wrightii on the composition of the associated algal community, in rocky and sandy habitats on the coast of Ceará in northeastern Brazil. The phycological community included 18 species in 10 families, members of Rodophyta (72.2%), Chlorophyta (22.2%) and Phaeophyceae (5.5%). The largest proportion were epilithic ...

Heterotrophic Bacillus amyloliquefaciens (MTCC 12716) isolated from the red alga Hypnea valentiae exhibited promising antibacterial activity (minimum inhibitory concentration of ≤1.0 µg/mL) against clinically relevant pathogens. The bacterium displayed bile salt and acid tolerance up to 4 h in a simulated gastric fluid, along with prospective antioxidant effect. This non-hemolytic was found be ...
