Phycobilisomes (PBS) are accessory light harvesting protein complexes that directionally transfer energy towards photosystems. Phycobilisomes are organized in a central core and rods radiating from it. Components of phycobilisomes in Gracilaria chilensis (Gch) are Phycobiliproteins (PBPs), Phycoerythrin (PE), and Phycocyanin (PC) in the rods, while Allophycocyanin (APC) is found in the core, an...
This study investigated the effect of Sargassum angustifolium and Gracilaria pulvinata extracts on the growth performance, body composition, antioxidant status and gut microbiota of rainbow trout (Oncorhynchus mykiss) fry. For this purpose, 540 fry of rainbow trout (initial weight 0.23±0.04 g) were distributed in 12 fiberglass tanks. Fish were fed with experimental diets containing 500 mg kg-1 ...
Seaweeds survive in marine waters with high sulfate concentration compared to those living at freshwater habitats. The cell wall polymer of Gracilaria spp. which supplies more than 50% of the world agar is heavily sulfated. Since sulfation reduces the agar quality, it is interesting to investigate the effects of sulfate deprivation on the sulfate contents of seaweed and agar, as well as the met...
کربوهیدراتهای طبیعی موجود در گیاهان در صنایع غذایی به لحاظ استفاده به عنوان منبع انرژی و موارد متعدد دیگر از اهمیت ویژه ای برخوردار می باشند. آگار ماده ای ژلاتینی است و ترکیب دی ساکارید Agarobiose، ساختمان عمومی ثابتی از تمام پلی ساکارید های موجود در آگار است. ساختار شیمیایی آگار باعث شده است که آگار ماده بسیار مفیدی برای بیشتر صنایع از جمله صنعت نساجی، دارویی، غذایی و همچنین علوم آزمایشگاهی ...
alcoholic extracts of 8 different types of seaweeds from iran's persian gulf were tested for their antimalarial and acetylcholinesterase enzyme (ache) inhibitory activities for the first time. a modified ellman and ingkaninan method was used for measuring ache inhibitory activity in which galanthamine was used as the reference. the antimalarial assay was performed using microculture radioisotop...
Phycobiliproteins, the main polypeptidic components of the phycobilisomes (PBS), are biological macromolecules arranged in complex interaction systems to perform light harvesting and conduction. The optical properties of these systems can hardly be studied by conventional spectroscopic techniques. Furthermore this techniques also involve laborious chemical extraction methods. Photoacoustic (PA)...
A design of experiments was applied to evaluate different strategies to enhance the methane yield of macroalgae Gracilaria vermiculophylla. Biochemical Methane Potential (BMP) of G. vermiculophylla after physical pre-treatment (washing and maceration) reached 481±9 L CH4 kg(-1) VS, corresponding to a methane yield of 79±2%. No significant effects were achieved in the BMP after thermochemical pr...
Intensive aquaculture practices involve rearing fish at high densities. In these conditions, fish may be exposed to suboptimal dissolved O2 levels with an increased formation of reactive O2 species (ROS) in tissues. Seaweeds (SW) contain biologically active substances with efficient antioxidant capacities. This study evaluated the effects of dietary supplementation of heat-treated SW (5% Gracil...
