High-quality marine ecosystems are free from global trending pollutants’ (GTP) contaminants. Accuracy and caution needed during the exploitation of resources tourism to prevent future ecological hazards that cause chain effects on aquatic humans. This article identifies exposure GTP: microplastic (MP); polycyclic aromatic hydrocarbons (PAH); pesticide residue (PR); heavy metal (HM); medical waste (MW), in area (MTA) Barrang Caddi Island (BCI) waters. A combination qualitative quantitative analysis methods were used with analytical instruments mathematical formulas. The search results show average total abundance MPs seawater (5.47 units/m3) fish samples (7.03 units/m3), as well sediment sponge (8.18 (8.32 units/m3). Based an polymer structure, it was identified dominant light group MPs: polyethylene (PE); polypropylene (PP); polystyrene (PS); followed by polyamide-nylon (PA); polycarbonate (PC). Several PAH pollutants samples. In particular, naphthalene (NL) types most common all samples, pyrene (PN), azulene (AZ). Pb+2 Cu+2 around BCI successfully calculated, showing concentrations 0.164 ± 0.0002 mg/L 0.293 0.0007 mg/L, respectively, while fish, 1.811 µg/g 4.372 0.0003 µg/g, respectively. these findings, is not recommended a destination.

Marine sponges usually host a wide array of secondary metabolites that play crucial roles in their biological interactions. The factors influence the intraspecific variability metabolic profile organisms, production or ecological function remain generally unknown. Understanding this may help predict changes relationships due to environmental variations as consequence climate change. sponge Dendrilla antarctica is common shallow rocky bottoms Antarctic Peninsula and known produce diterpenes are supposed have defensive roles. Here we used GC-MS determine major two populations D. from islands, Livingston Deception Island (South Shetland Islands). To assess potential effect heat stress, exposed aquaria control temperature (similar local), stress (five degrees higher) extreme (ten higher). test for defence induction by predation pressure, sea star Odontaster validus amphipod Cheirimedon femoratus. Seven were isolated identified samples. While six them already reported literature, one new aplysulphurane derivative was more abundant samples Island, so named it deceptionin (7). separated PCA space according island collection, with 9,11-dihydrogracilin A (1) being Livingston, (7) Deception. We found slight on diterpene profiles antarctica, tetrahydroaplysulphurin-1 (6) gracilane norditerpene 2 group stress. Predation pressure did not seem metabolite production. Further research bioactivity metabolites, responses will better understand functioning fate benthos.

A quality marine ecosystem if it is free from GTP contaminants. Accuracy and caution are needed in the exploitation of resources as tourism destinations so that future, there will be no ecological hazards cause chain effects, not only on aquatic ecosystems but also humans. This article identifies exposure to (MP, PAH, PR, HM, MW) MTA area BCI waters. The combination qualitative quantitative analysis methods uses a analytical instruments mathematical formulas. search results show average total abundance MP seawater fish samples (5.47 units/m3) (7.03 units/m3), respectively, while sediment sponge (8.18 (8.32 units/m3). Based polymer structure, was identified dominant light group (PE, PP PS), followed by PA PC. Several PAH pollutants were samples, especially NL types found all PN AZ. sea waters suspected exposed MW PR.

Bioremediation Performance of Marine Sponge Symbiont Bacteria against Nickel and Mercury Heavy Metal Pollutants

International Journal on Advanced Science Engineering and Information Technology, Год журнала: 2023, Номер 13(2), С. 544 - 544

Опубликована: Апрель 15, 2023

Heavy metals, mercury, and nickel are toxic contaminants, forming positive ions when concentrated dissolved, can accumulate in a specific object, including water. The activity performance of bacterial bioremediation against heavy metals vary due to characteristics internal contaminant factors. This research aims analyze the activity, performance, efficiency mercury pollutants using marine sponge symbiont bacteria. analysis procedure, suspension bacteria Alcaligenes faecalis strain Cu4-1 (AF), Acinetobacter calcoaceticus PHCDB14 (AC) interacted with metal as contaminants for 15 days. Bioremediation were measured AAS. parameters consisted efficiency, mechanism pollutants. results show that AF AC carry out function Ni+2 Hg+2 contaminants. pollutant is, on average 167.64±0.9 mg/L, equivalent 66.85% an 171.55±0.7 65.47%. was 168.92±0.7 or reached 66.97%, 145.87±0.8 Hg+2, 58.35% efficiency. ˂ pollutants, but ˃ symbiotic sponges thought have isolated from whose body surface is covered mucus substances.

Culturable Actinobacteria from Two Marine Sponges of the Genus Aplysina in Southwest Puerto Rico

Caribbean Journal of Science, Год журнала: 2024, Номер 54(1)

Опубликована: Март 27, 2024

Actinobacteria are the most biotechnologically valuable prokaryotes and best known as a source of diverse secondary metabolites. However, there is scarce information on marine actinobacterial diversity in Caribbean Sea. In this study, was examined through culture-dependent methods sponges Aplysina fistularis fulva. Sponge specimens were collected by SCUBA diving La Parguera Natural Reserve Lajas, Puerto Rico. A total 62 isolates obtained from sponge samples identified phylogenetic analysis based 16S rRNA gene. The isolated phylogenetically allocated to 18 genera. A. fulva yielded more (39) than (24). terms genus diversity, higher variety observed (17 genera) (7 genera). Even though approach can give us insight into sponge's microbiome an important basis for study compounds that produced Actinobacteria, strategy limited because it does not reveal all may be present since small portion bacteria culturable. Moreover, partial sequence gene often contain enough provide species-level resolutions. Ecological studies will improve our understanding associated with different ecosystems could lead discovery useful bioactive compounds.

Positive feedbacks in coastal reef social-ecological systems can maintain coral dominance

ICES Journal of Marine Science, Год журнала: 2024, Номер unknown

Опубликована: Дек. 13, 2024

Abstract Understanding the mechanisms underlying nutrient (nitrogen and phosphorus) carbon cycling in reefs is critical for effective management. Research on reef needs to account (i) contributions of multiple organisms, (ii) abiotic biotic drivers, (iii) a social-ecological perspective. In this paper, we review systems analyse them using causal loop analysis. We identify direct indirect pathways feedback loops through cycles that shape dominant benthic state reefs: coral, algal, sponge-dominated states. find two three anthropogenic impact scenarios (size-selective fishing land use change) have primarily negative consequences coral macroalgae via cycles. A third scenario (runoff) has fewer impacts sponges compared other benthos. all scenarios, frequent positive fishing: 7 12 loops; runoff: 6 9 change: 8 11 loops) lead system destabilization; however, presence introduces avenues whereby may retain dominance despite pressures. Context-specific information relative strength will be necessary predict future state.

Potential Utilization of Bacterial Consortium of Symbionts Marine Sponges in Removing Pollutants Global Trends: A Review

Опубликована: Сен. 5, 2022

Toxic materials in waste generally contain several components of global trending pollutant categories, especially PAHs and heavy metals. Bioremediation technology for managing utilizing microorganisms (bacteria) has not been fully capable breaking down these toxic simple environmentally friendly chemical products. This study examines the potential application a marine sponge symbiont consortium with high performance efficiency removing metal contaminants. The method is carried out through review some related research articles by author published other re-searchers. results concluded that bioremediation development GTP, can be to improve remediation efficiency. Several types bacteria, hydrocarbonoclastic (R-1), metalloclastic (R-2), metallohydro-carbonoclastic (R-3), have applied removal waste. Bacterial screening done find categorize R-1 R-2; R-3 remediate GTP. Develop forms mobile formulation are needed future. A crystalline bacteria preparations so they quickly mobilized locations exposed Marine traced mainly sponges whose body surface covered mucus.
