Abstract:
As plastic waste is currently an exponentially urgent issue, the usage of bioplastics to replace synthetic plastics would help to resolve the existing pollution. In addition to providing the nutrients and minerals required for the culture medium, the waste sources and byproducts of the seafood processing industry also include a wide variety of nutrients. The fat produced during the processing of the byproducts would also be a viable, affordable supply of carbon for microbial strains that can make bioplastics in the water. Particularly in this study, 191 strains were selected for growth and use of aquatic byproducts from marine habitats. The fluorescence microscopy analysis of these strains’ capacity to collect PHA revealed that 35 of the strains treated with Nile blue A displayed bright orange hue. The three strains GB300, GB505, and GB515 with the best density and accumulated plastic particle size were gathered using transmission electron microscopy pictures. These three strains are known to belong to three genera based on morphological traits, culture traits, and 16S rRNA gene sequences: two genera are actinomyces (Marmoricola sp. and Piscicocus sp.), and one strain belongs to the genus Labrenzia. Three marine microbial strains’ 16S rRNA gene sequences were stored in the Genbank under the accession numbers MN519525, MN519529, and MN525591, respectively corresponding to GB505, GB300, and GB515.
Keywords:Bioplastics, PHA, PHB, Aquatic Organism, Actinomyces.

Abstract:
The importance of network security has grown significantly in recent years. With the widespread use of the Internet, consumers, companies, and military clients have become increasingly vulnerable to security threats such as hacking, malware, and phishing attacks. Therefore, security has become a top priority for many organizations. Over time, the evolution of security technology has led to a better understanding of the field of network security. The area of community protection is vast and continuously evolving, encompassing a wide range of strategies, technologies, and protocols. The topic of observation in this article includes news from the days before the internet as well as more recent advancements in community protection. By analyzing current research techniques, previous defense strategies that were effective, and network attack techniques that have been used before, we can gain a better understanding of how to improve network security. This article’s focus is on the security of various domain names, which is explored through a bibliographic research approach.
Key Words:Network security; internet security; community protection; defense strategies; network attack techniques; domain name security; security technology; security protocols, software, hardware tools; PC network infrastructure; access rights; IT facilities; message encryption.
