Seaweed produces metabolites aiding in the protection against different environmental stresses. These compounds show antiviral, antiprotozoal, antifungal, and antibacterial properties. Macroalgae can be cultured in high volumes and would represent an attractive source of potential compounds useful for unconventional drugs able to control new diseases or multiresistant strains of pathogenic micr...

abstract the aim of this study was the identify cyanobacterial flora of rice–fields in dargaz, to interaction between cyanobacteria by culturing in solid medium bg-110 in laboratory was investigated. nostoc piscinale and nostoc spongiaeforme were identified as strongest and weakness species, respectively, regarding secondary metabolits producing (allelochemicals).the algal pairs were classified...

wood resources, non-wood plants and recycled papers are the common raw materials of papermaking. shortage of raw materials, is a challenging problem in developing pulp and paper industry. in this study, cladophora green algae was used as a new source of cellulosic fiberfor pulping and papermaking.. cladophora algae was cooked with cold soda method and then was mixed with nssc pulp at 10,20 and ...

Nowadays, natural microbial pigments are emerging as potential candidate therapeutic agents that can be used in antibiotic resistance. In this paper, we report the antimicrobial activity of green algae pigments. Green SC3 isolate was isolated from soil Erzurum. Pigments extracted by methanol: dimethyl sulfoxide solvents were partially characterized Thin Layer Chromatography (TLC), UV-Absorbance...

For the isolation of blue-green algae from soil and fresh water, temperature is a selective factor of major importance. In a nutritionally non-selective mineral medium, which at 25" supported growth of blue-green algae and of many eucaryotic algae, the development of eucaryotic algae was almost completely suppressed by incubation at 35". Both the number and variety of blue-green algae recoverab...

The aim of this study was to identify seaweeds in the southern coasts of Iranian waters and providing an atlas. The collecting and identification of seaweeds in the southern coasts of Iranian waters were carried out from October 2001 to September 2003. Data on vegetation were gathered in sub tidal and intertidal zones by seasonal and monthly sampling, respectively. Samples were transferred to t...

Green algae as one of the marine natural resources which is included in main seaweed found many coastal areas In-donesia. The bioactive component that acts an antibacterial agent green type Ulva lactuca ulvan polysaccharide extract. Ulvan a cell wall accounts for 9-36% dry weight biomass and mainly composed rhamnose sulfate, uronic acid (glucuronic iduronic acid) xylose. Polysaccharide extracte...
