background & aim: in this study, is done during one-year research on blue–green and green algae for antimicrobial activity in mashhad suburb. aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. material & meth...
biodegradation of different concentration of dye (congo red dye) by using green and blue green algae
releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...

Nitrogen fixation blue-green algae make a major contribution to the fertility of soil. It has been suggested that blue-green algae (BGA) assist higher plant growth by supplying growth substances. There are numerous works about roles of blue-green algae in paddy soils and rice growth but little on other plants. In this research, 19 morphospecies belonging to three families of heterocystous and n...
Marine algae are shown to contain a wide range of bioactive compounds, which have commercial application in pharmaceutical, medical, cosmetic, nutraceutical, food and agricultural industries. The biological activity of the natural bio-active compounds in algae has wide effects on bacteria, tumors and antioxidant activities. The purpose of this study was to determine antibacterial activity of th...
The effect of macro green algae (Chaetomorpha gracilis) inf Bandar-Abbas and filamentous green algae (Spirogyra sp.) in the Sirch river (Kerman Province) were assayed on growth characteristics of the tomato (Lycopersicum sculentum). In the seed priming experiment, we collected hot water extracts of green algae (Chaetomorpha gracilis) from Bandar Abbas seashores and filamentous green algae (Spir...
With regard to the importance of polychaete Perinereis nuntia in diet of shrimp broodstock, achieving its breeding and culture bio technique is an important goal in shrimp industry. For this purpose, usage of diets inducing the highest growth and the lowest mortality is of importance. The effect of four different dietary treatments including commercial shrimp diet- Biomar, Lansy shrimp diet con...
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 ...
