Anxiety of microbially synthesized FeO-SPIONs on embryonic/larval ontogeny in red tilapia (Oreochromis sp.).

Iron oxide nanoparticles, recognized for their superparamagnetic properties, are promising for future healthcare therapies. However, their extensive use in medicine and electronics contributes to their discharge into our environments, highlighting the need for further research on their cellular damage effects on aquatic organisms. While the detrimental properties of other compounds have been stated in the early-life stages of fish, the cytotoxic consequences of superparamagnetic iron oxide nanoparticles (SPIONs) in these stages are still unexplored.

Distribution and functional perspective analysis of epiphytic and endophytic bacterial communities associated with marine seaweeds, Alexandria shores, Egypt.

There is an enormous diversity of life forms present in the extremely intricate marine environment. The growth and development of seaweeds in this particular environment are controlled by the bacteria that settle on their surfaces and generate a diverse range of inorganic and organic chemicals. The purpose of this work was to identify epiphytic and endophytic bacterial populations associated with ten common marine macroalgae from various areas along the Mediterranean Sea coast in Alexandria.

Copper oxide nanoparticles (CuO-NPs) as a key player in the production of oil-based paint against biofilm and other activities.

Copper oxide nanoparticles are among the metal nanoparticles gaining popularity in many biotechnological fields, particularly in marine environments. Their antimicrobial and antibiofilm activities make them appealing to many researchers. Among the various methods of producing nanoparticles, biosynthesis is crucial.

Functionalized maghemite superparamagnetic iron oxide nanoparticles (γ-FeO-SPIONs)-amylase enzyme hybrid in biofuel production.

The current study describes a straightforward, biologically and environmentally friendly method for creating magnetic iron oxide (γ-FeO) nanoparticles. We report here that the Bacillus subtilis SE05 strain, isolated from offshore formation water near Zaafarana, the Red Sea, Hurghada, Egypt, can produce highly magnetic iron oxide nanoparticles of the maghemite type (γ-FeO). To the best of our knowledge, the ability of this bacterium to reduce FeO has yet to be demonstrated.

Large scale production of superparamagnetic iron oxide nanoparticles by the haloarchaeon Halobiforma sp. N1 and their potential in localized hyperthermia cancer therapy.

Magnetic iron oxide nanoparticles are among metal nanoparticles that attract huge attention in many biotechnological fields especially in the biomedical area. Their extensive capabilities and easy separation methodology drive them to be an interesting point to many researchers. Biosynthesis is of a major importance among different methods of nanoparticles production.

Novel research on nanocellulose production by a marine Bacillus velezensis strain SMR: a comparative study.

Bacterial nanocellulose (BNC) is a nanofibrillar polymer that possesses unique characteristics such as high chemical purity, mechanical strength, flexibility, and absorbency. In addition, different bacterial strains can form nanocellulose (NC) in multiple shapes and sizes. This study describes the first report of a marine Bacillus strain that is able to synthesize NC.
