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...

Macroalgal blooms of Hypnea musciformis and Ulva fasciata in coastal waters of Maui only occur in areas of substantial anthropogenic nutrient input, sources of which include wastewater effluent via injection wells, leaking cesspools and agricultural fertilizers. Algal dN signatures were used to map anthropogenic nitrogen through coastal surveys (island-wide and fine-scale) and algal deployments...

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 ...

the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...
