Macroalgae are considered as primary producers in ecosystem food chain. This study investigated spatial and temporal variation of three species of macroalgae namely, Laurencia caspica (red macroalga) Enteromorpha intestinalis and Cladophora glomerata (green macroalgae) on the hard substrates of the southern Caspian Sea coasts and their relation with environmental factors. Seasonal sampling pref...
Persian Gulf is known as an environmental resource of unique species. In the present survey, the floristic composition of marine algae of Hengam Island in Hormozgan province was investigated. Sampling was performed at four stations of the tidal zone from March 2012 to April 2014.45 marine algae species were identified in Hengam Island including23, 11 and 11 species belong to Rhodophyceae, Chlor...
The nutritional values of the three Caspian Sea macroalgae species, Cladophora glomerata, Enteromorpha intestinalis and Laurencia caspica were evaluated based on proximate and fatty acid composition. The investigated species demonstrated low lipid composition (0.20±0.03- 1.62±0.26 % DW) and high carbohydrate (21.70±0.17-26.1±1.27%DW) and protein contents (13.34±2.41-28.08±0.51%DW). The as...
In Laurencia dendroidea, halogenated secondary metabolites are primarily located in the vacuole named the corps en cerise (CC). For chemical defence at the surface level, these metabolites are intracellularly mobilised through vesicle transport from the CC to the cell periphery for posterior exocytosis of these chemicals. The cell structures involved in this specific vesicle traffic as well as ...
Two new diphenylketones (1 and 2), a new xanthone (3), and a known xanthone analogue (4) were isolated and identified from Talaromyces islandicus EN-501, an endophytic fungus obtained from the fresh collected marine red alga Laurencia okamurai. Their structures were elucidated on the basis of NMR spectroscopic and X-ray crystallographic analysis. The joint isolation of benzophenones and xanthon...
