“…Accordingly, it can be said that it resists endocrine alterations during the development stages. The validation of the model was done with a series of intra‐ and interlaboratory bioassays, allowing the use of B. amphitrite larvae as test organisms for ecotoxicological studies, complying with international precision standards both within and between laboratories (Abdulrahman et al, 2022). It should be noted that the endocrine disruption caused by this type of contaminant in these organisms is through the blocking or mimicry of the natural hormone in the specific binding site, because these contaminants generally have a chemical structure very similar to this hormone; thus the contanimant can enter the cytoplasm or cell nucleus without any problem from receptors.…”

“…The effects of exposure to the xenoestrogen, 4‐nonylphenol have also been examined in marine crustaceans, particularly levels of a larval storage protein, cypris major protein, which is related to the vitellin of B. amphitrite , a dominant encrusting invertebrate in the marine environment (Matozzo et al, 2008). Larval and adult stages are considered an important model for examining the environmental pollutants that pose a potential threat to marine organisms and affect their ecosystems and coral reefs (Abdulrahman et al, 2022).…”

Certain emerging pollutants are among the most widely used chemicals globally, causing widespread concern in relation to their use in products devoted to cleaniness and asepsis. Nonylphenol ethoxylate (NPEOn) is one such contaminant, along with its degradation product, nonylphenol, an active ingredient presents in nonionic surfactants used as herbicides, cosmetics, paints, plastics, disinfectants, and detergents. These chemicals and their metabolites are commonly found in environmental matrices. Nonylphenol and NPEOn, used, are particularly concerning, given their role as endocrine disruptors chemical and possible neurotoxic effects recorded in several biological models, primarily aquatic organisms. Limiting and detecting these compounds remain of paramount importance. The objective of the present review was to evaluate the toxic effects of nonylphenol and NPEOn in different biological models.

“…Several studies have reported high antifouling activity potential in bioactive compounds from B. licheniformis (Ortega-Morales et al 2008;Aguila-Ramírez et al 2014;Eduok et al 2015;Muras et al 2021a). Many species have been isolated from soft corals with a demonstrated ability to produce compounds with antifouling activity (Pham et al 2016;Hou et al 2019;Abdulrahman et al 2022a;Abdulrahman et al 2022b , Ba-akdah & Satheesh 2021. It has been isolated from the surface of a macroalga and has demonstrated good antifouling activity through the production of relevant compounds (Tilmann et al 2004).…”

In marine environments where biofouling occurs and has an impact on the maritime economy and environment, compounds that inhibit the attachment, growth and survival of microorganisms in a biofilm complex as well as settlement of larvae are considered potential antifouling compounds. In this study, the extracellular metabolites from two surface- associated bacteria isolated from soft coral and macroalga were evaluated for antibiofilm and antisettlement activity. The bacteria were identified using 16S rRNA gene sequencing, and the culture supernatant extract of each strain was evaluated for antibiofilm activity. The compounds present in the extracts were analysed using GC-MS. The two bacterial strains were identified as Bacillus licheniformis MBR1 and Vibrio alginolyticus MBR4 for the isolates from soft coral and macroalgae, respectively. The extracts inhibited the growth of biofilm-forming bacteria, biofilm formation and barnacle larval settlement. The GC-MS analysis of the extract detected the presence of compounds such as tetrapentacontane, octadecanoic acid, 2,3-dihydroxypropyl ester, hexadecanoic acid, 2-hydroxy1-(hydroxymethyl) ethyl ester and 17-pentatriacontene. The results of the study show that extracellular metabolites of the bacteria associated with marine organisms could be used as natural antifouling compounds to control biofouling.
