Antioxidant Activity of Six Marine Sponges Collected from the Persian Gulf

Antimicrobial Effects of Some Persian Gulf Marine Sponges

Background: We investigated in vitro antimicrobial activity of five marine sponge species collected from Kish Island in the Persian Gulf: Fascaplysinopsis reticulata, Callyspongia clavatus, Callyspongia siphonella, Niphates furcata, and Pseudosuberites clavatus against gram positive bacteria, gram negative bacteria, fungi and yeasts. Materials and Methods: Sponage extracts were prepared by two ...

Comparison of Antioxidant Activity and Total Phenolic Contents of some Persian Gulf Marine Algae

Background: Marine algae, especially brown species, produce a wide range of metabolites with various biological activities. Objective: Since marine algae are rich source of dietary fibers, minerals, proteins, vitamins and phenolic components with antioxidant effect, in addition to the rule of oxidative stress in pathogenesis of chronic diseases, the aim of this study was to investigate possib...

Antioxidant Activity of Extracts of Selected Algae from the Persian Gulf, Iran

In vitro antioxidant activity of Ulva lactuca (Chlorophyta) and three brown seaweeds belonging to the division Phaeophyta were evaluated. The species Padina pavonica, Colpomenia sinuosa, Cystoseira myrica and U. lactuca were collected during low tide between March and June 2012 from the coastline of the Persian Gulf (Hormozgan and Bushehr provinces), Iran.Ethyl acetate, n-Hexane and methanol e...

Evaluation of in vitro anti-leishmaniasis activity of three marine species from Persian Gulf

Introduction: Recently, the drugs with marine resources have been considered due to the lower costs and greater compatibility with patients. In the present study, the extracts of three marine organisms from the Persian Gulf; Holothuris parva, Ophiocoma scolopendrina and Echinometra matheai, were prepared and evaluated their in vitro anti-leishmaniasis effects. Materials & Methods: All three mar...

Isolation and evaluation of cytotoxic and antioxidant activity of bioactive metabolites of cultured actinobacteria in Persian Gulf marine sediments

Screening bacteria for bioactive compounds is the first step in the drug discovery programs. The aim of the present research was to achieve cytotoxic and antioxidant metabolites from actinobacteria of Persian Gulf sediments and to investigate the effects of combinations of seven treatments and six isolation media on the selective isolation process. A total of 395 actinobacterial isolates were c...
