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...

The present study was conducted to investigate the effect of the diet containing Laurencia caspica (red algae) on blood parameters and digestive enzymes activity of goldfish after 90-day period. Goldfish (weight 6.10±0.1 gr) were divided to four experimental groups (30 individuals in each replication) including experimental treatment of the control group (without using red algae) and three trea...

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...

Red tide is a natural phenomenon that changes sea color by harmful algal bloom. There has been a lot of study on red tide due to increasing of red tide damage. However, to automatically recognize the red tide algae images present in previous studies are not enough. It is difficult to recognize red tide algae images because they do not have matching features for recognizing various species of al...

We conducted this study to investigate the effect of culture depth of red algae Gracilaropsis persica on the growth and biomass production of this species. Three culture depth of 5, 6, and 7 m were used to cultivate algae in the Persian Gulf (Bandar Abbas) for 45 days. Algae was collected from its natural environment and cultivated on polyethylene rope in the sea. We measured relative growth ra...

Porphyra umbilicalis (laver) belongs to an ancient group of red algae (Bangiophyceae), is harvested for human food, and thrives in the harsh conditions of the upper intertidal zone. Here we present the 87.7-Mbp haploid Porphyra genome (65.8% G + C content, 13,125 gene loci) and elucidate traits that inform our understanding of the biology of red algae as one of the few multicellular eukaryotic ...

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...

The low photosynthetic efficiency of chlorophyll in freshly collected red algae, can, in the case of Porphyra perforata, P. nereocystis, and Porphyridium cruentum, be increased by growing the algae for 10 days in red or blue light. Exposure to darkness or to green light maintains the algae in their originally low efficiency with respect to chlorophyll, while retaining the high efficiency of phy...
