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...

Chronic exposure of the skin to ultraviolet B (UVB) radiation induces oxidative stress, which plays a crucial role in the induction of skin cancer. In this study, the effect of dietary feeding and topical application of brown algae polyphenols on UVB radiation-induced skin carcinogenesis in SKH-1 mice was investigated. SKH-1 hairless mice were randomly divided into 9 groups, including control, ...

The use of ultrasound (US) to control algal growth in natural water bodies raises concern about the undesirable effects US on non-target organisms. In this study a lab-scale experiment was performed evaluate low-power counteract adult and juvenile Daphnia magna. 48-hour conducted 200 L glass aquarium with three fish nets, each filled five D. Each net inspected for immobilized magna different ti...

Introduction: Using bio-sorbents is regarded as one of the effective methods to remove heavy metals. Therefore, this study aimed to investigate Pb adsorption from contaminated water by Chaetoceros sp. and Chlorella sp. algae. Methods: This experimental study was conducted in a batch reactor. The amount of Pb adsorption by Chaetoceros sp. and Chlorella sp. algae was studied under such conditio...

one of the most important aims of aquatic hatcheries is availability to mass produce of daphnia magna as a live food with high nutritional value in the shortest time. in the present study, d. magna fed with two freshwater green algae species, chlorella sp. and scenedesmus obliquus, enriched with different dosages of a mixture b group vitamins (0, 0.5, 1 and 2 ml.l-1) were compared at two stages...

The identification of marine algae in the Sistan and Baluchestan Province were performed from December 1998 to November 1999 at the coastal area of Gwatr (25 10´ N; 61 30´ E) and Mydani (25 24´ N; 59 5´ E). Data on vegetation were gathered in subtidal and intertidal zones by seasonal and monthly sampling, respectively. Samples were transferred to the laboratory and fixed in 4% formalin. Accordi...

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 ...
