Seaweed genetic engineering is a transgenic expression system with unique features compared with those of heterotrophic prokaryotes and higher plants. This study discusses several newly sequenced seaweed nuclear genomes and the necessity that research on vector design should consider endogenous promoters, codon optimization, and gene copy number. Seaweed viruses and artificial transposons can b...

In recent years, there have been major advances and increasing amounts of research on the utilization of natural polymeric materials as drug delivery vehicles due to their biocompatibility and biodegradability. Seaweed polysaccharides are abundant resources and have been extensively studied for several biological, biomedical, and functional food applications. The exploration of seaweed polysacc...

Hepatitis C virus (HCV) has infected 3% of the population worldwide and 20% of the population in Egypt. HCV infection can lead to hepatocellular carcinoma and death. The presently available treatment with interferon plus ribavirin, has limited benefits due to adverse side effects. Seaweeds have become a major source of new compounds to treat viral diseases. This work aimed to study the effect o...

Impact of three different types of seaweed diets on growth, feed utilization and nutrient digestibility of L. rohita was studied for 120 days. The seaweed diet fed fishes, especially Ulva based diet showed comparatively higher growth and weight increment. Good food conversion ratio, food assimilation efficiency, protein efficiency ratio and better nutrient digestibility were recorded for seawee...

the synthesis, characterization and application of biologically synthesized nanomaterials are an important aspect in nanotechnology. the present study deals with the synthesis of silver nanoparticles (ag-nps) using the aqueous extract of red seaweed gelidiella acerosa as the reducing agent to study the antifungal activity. the formation of ag-nps was confirmed by uv-visible spectroscopy, x-ray ...

The negative effects of the ongoing climate change include unusual prolonged droughts and increased salinity pressures on the agricultural lands. Consequently, crops are facing unprecedented environmental pressure, and this calls for more research toward controlling such major stresses. The current study investigates the effects of seaweed extract sprays of Ascophyllum nodosum (5 and 7 mL·L-1; ...

Green synthesis of nanoparticles using seaweeds are fascinating high research attention nowadays and also gaining center of attention in biomedical applications. In this work, we have synthesized biocompatible and functionalized silver nanoparticles using an aqueous extract of seaweed Enteromorpha compressa as a reducing as well as stabilizing agent and their efficient antimicrobial and antican...

Seaweeds are primitive non flowering aquatic plants, which have been a source of food, feed and medicine since ancient times. The selected green seaweed U. fasciata collected from Gulf of Mannar is a unique marine habitat that belongs to the diverse class of seaweeds. Hence the present study was conducted with the specific objectives to explore the anticancer activity of green seaweed, Ulva fas...

Fucoidan is a uniquely-structured sulfated polysaccharide found in the cell walls of several types of brown seaweed that has recently, especially as enzyme-digested fucoidan extract, attracted a lot attention due to its anti-tumor potential. In this study, we evaluated the effects of enzyme-digested fucoidan extracts prepared from seaweed Mozuku of Cladosiphon novae-caledoniae kylin on in vitro...
