“…Many plastics can absorb natural and mineral toxins from the concentrate and the environment up to a million times the concentrations found in seawater 1 , 2 . In addition, the primary sources of chitin are the shells of marine crustaceans, which are mostly made up of 20–30% chitin, 30–50% calcium carbonate, 30–40% protein and calcium phosphate 3 , 4 . A variety of industries, including agriculture, wastewater treatment, medication delivery, tissue engineering, molecular imprinting, cosmetics, and food preservation, have been reported by numerous authors to use chitin and its derivatives 5 – 9 .…”

Biodegradable plastics are those subjected easily to a degradation process, in which they can be decomposed after disposal in the environment through microbial activity. 30 bioplastic film formulations based only on chitosan film were used in the current investigation as a positive control together with chitosan film recovered from chitin-waste of locally obtained Aristeus antennatus. Additionally, castor oil was used as a plasticizer. While the yield of chitosan was 18% with 7.65% moisture content and 32.27% ash in the shells, the isolated chitin had a degree of deacetylation (DD) of 86%. The synthesized bioplastic films were characterized via numerous criteria. Firstly, the swelling capacity of these biofilms recorded relatively high percentages compared to polypropylene as synthetic plastic. Noticeably, the FTIR profiles, besides DSC, TGA, and XRD, confirmed the acceptable characteristics of these biofilms. In addition, their SEM illustrated the homogeneity and continuity with a few straps of the chitosan film and showed the homogeneous mixes of chitosan and castor oil with 5 and 20%. Moreover, data detected the antibacterial activity of different bioplastic formulas against some common bacterial pathogens (Enterococcus feacalis, Kelbsiella pnumina, Bacillus subtilis, and Pseudomonas aeruginosa). Amazingly, our bioplastic films have conducted potent antimicrobial activities. So, they may be promising in such a direction. Further, the biodegradability efficacy of bioplastic films formed was proved in numerous environments for several weeks of incubation. However, all bioplastic films decreased in their weights and changed in their colors, while polypropylene, was very constant all the time. The current findings suggest that our biofilms may be promising for many applications, especially in the field of food package protecting the food, and preventing microbial contamination, consequently, it may help in extending the shelf life of products.

“…The standard molecular sequencing identification system was introduced during the 1990s with DNA sequencing by polymerase chain reaction. DNA barcoding was successfully used for detection of aquaculture-based product modifications and also to identify different shrimp species from the Mediterranean and Red Sea (Asmaa Galal-Khallaf et al 2014;El-Sharawy et al 2017;Ahmed et al 2021).…”

A native of North America, the brine shrimp Artemia franciscana is now a very invasive foreign species that has already been imported to most of the world. Before the introduction of A. franciscana, Asia was home to a wide range of bisexual Artemia species, which is no longer the current case. The collected Artemia samples from salt pans in south India were subjected to exact species identification and determination of phylogeographic origin through morphometric and molecular phylogenetic analysis. The Artemia species was validated with the observation of spiny subspherical frontal knob and distinctive lateral triangular ovisac lobes with projections on its body. The phylogenetic analysis of these Artemia species from two sampling localities was carried out after nucleic acid sequencing. After DNA barcoding of the cytochrome oxidase COI gene, the samples were identified as belonging to A. franciscana.
