“…As reported by Tinta et al [35] early reports on microorganisms associated with jellyfish resulted as corollary observations, whereas primary targets of research were jellyfish [33,36,37]. Later studies, focusing on the relationships between microorganisms and their host organisms, addressed more specific issues on the composition and ecological role of jellyfish-associated microbial communities [35,38,39]. In the last decades, many studies revealed the role played by microorganisms in coral life histories, particularly the dynamic assemblage formed by the coral host, its endosymbiotic dinoflagellates, and a number of accompanying microorganisms, i.e., the coral holobiont [40][41][42].…”

“…So far, a limited number of studies explored different types of interactions between marine microbial communities and scyphozoan jellyfish, from host-microbiome interactions to quali-quantitative changes of microbial composition sampled across different life stages, medusa body parts, water samples, mostly on common semeostome jellyfish [22,23,35,38,[49][50][51][52][53][54][55]. To our knowledge, Mastigias papua, Cotylorhiza tuberculata, and Rhizostoma pulmo are the only rhizostome jellyfish species previously investigated with respect to their associated microbial community [39,50,51,55,56].…”

Jellyfish blooms are frequent and widespread in coastal areas worldwide, often associated with significant ecological and socio-economic consequences. Recent studies have also suggested cnidarian jellyfish may act as vectors of bacterial pathogens. The scyphomedusa Rhizostoma pulmo is an outbreak-forming jellyfish widely occurring across the Mediterranean basin. Using combination of culture-based approaches and a high-throughput amplicon sequencing (HTS), and based on available knowledge on a warm-affinity jellyfish-associated microbiome, we compared the microbial community associated with R. pulmo adult jellyfish in the Gulf of Taranto (Ionian Sea) between summer (July 2016) and winter (February 2017) sampling periods. The jellyfish-associated microbiota was investigated in three distinct compartments, namely umbrella, oral arms, and the mucus secretion. Actinobacteria, Bacteroidetes, Chlamydiae, Cyanobacteria, Deinococcus-Thermus, Firmicutes, Fusobacteria, Planctomycetes, Proteobacteria, Rhodothermaeota, Spirochaetes, Tenericutes, and Thaumarchaeota were the phyla isolated from all the three R. pulmo compartments in the sampling times. In particular, the main genera Mycoplasma and Spiroplasma, belonging to the class Mollicutes (phylum Tenericutes), have been identified in all the three jellyfish compartments. The taxonomic microbial data were coupled with metabolic profiles resulting from the utilization of 31 different carbon sources by the BIOLOG Eco-Plate system. Microorganisms associated with mucus are characterized by great diversity. The counts of culturable heterotrophic bacteria and potential metabolic activities are also remarkable. Results are discussed in terms of R. pulmo ecology, the potential health hazard for marine and human life as well as the potential biotechnological applications related to the associated microbiome.

“…Their potential influences on corals may be diverseranging from beneficial to opportunistic. Members of the genus Phaeobacter were previously found in corals and jellyfish [43][44][45] and were linked to the production of antibacterial compounds in fishes [46,47]. Bacteria from the genus Oceanospirillum are frequently observed in healthy coral colonies [48,49], while members of the phylum Lentisphaerae are common in the fish gut [50] and healthy corals [48].…”

Parrotfish predation drives distinct microbial communities in reef-building corals

et al. 2020

Background: Coral-associated microbial communities are sensitive to multiple environmental and biotic stressors that can lead to dysbiosis and mortality. Although the processes contributing to these microbial shifts remain inadequately understood, a number of potential mechanisms have been identified. For example, predation by various corallivore species, including ecologically-important taxa such as parrotfishes, may disrupt coral microbiomes via bite-induced transmission and/or enrichment of potentially opportunistic bacteria. Here, we used a combination of mesocosm experiments and field-based observations to investigate whether parrotfish corallivory can alter coral microbial assemblages directly and to identify the potentially relevant pathways (e.g. direct transmission) that may contribute to these changes.Results: Our mesocosm experiment demonstrated that predation by the parrotfish Chlorurus spilurus on Porites lobata corals resulted in a 2-4x increase in bacterial alpha diversity of the coral microbiome and a shift in bacterial community composition after 48 h. These changes corresponded with greater abundance of both potentially beneficial (i.e. Oceanospirillum) and opportunistic bacteria (i.e. Flammeovirgaceae, Rhodobacteraceae) in predated compared to mechanically wounded corals. Importantly, many of these taxa were detectable in C. spilurus mouths, but not in corals prior to predation. When we sampled bitten and unbitten corals in the field, corals bitten by parrotfishes exhibited 3x greater microbial richness and a shift in community composition towards greater abundance of both potential beneficial symbionts (i.e. Ruegeria) and bacterial opportunists (i.e. Rhodospiralles, Glaciecola). Moreover, we observed 4x greater community variability in naturally bitten vs. unbitten corals, a potential indicator of dysbiosis. Interestingly, some of the microbial taxa detected in naturally bitten corals, but not unbitten colonies, were also detected in parrotfish mouths. Conclusions: Our findings suggest that parrotfish corallivory may represent an unrecognized route of bacterial transmission and/or enrichment of rare and distinct bacterial taxa, both of which could impact coral microbiomes and health. More broadly, we highlight how underappreciated pathways, such as corallivory, may contribute to dysbiosis within reef corals, which will be critical for understanding and predicting coral disease dynamics as reefs further degrade.

“…The importance of fungi as a new source of bioactive compounds was first focused by the discovery of penicillin from Penicillium notatum in 1928 by Alexander Flemming. A molecular study reported that fungal communities differ between marine lives collected at the same site and also differ from those present in the surrounding marine water [18][19][20] . Up to 2016, nearly 600 new compounds were reported from marinederived symbiotic microorganisms of which over 70% were obtained from epi/endophytes derived from marine weeds, invertebrates and woody substrates 21 .…”

Endophyte is a rich source of bioactive metabolites for medicinal exploitation as an increasing number of novel compounds with bioactive potential are now being isolated from this source. This study was conducted to characterize and explore endophytic fungi from marine weeds available in Bangladesh. The whole weed was used for isolation of endophytic fungi in the water agar media and the isolated fungi were identified through macroscopic and microscopic observation. Small scale cultivation was performed on liquid Wickersham media. Cytotoxicity, antibacterial, antioxidant activities were evaluated following brine shrimp lethality bioassay, disc diffusion method and DPPH free radical scavenging assay, respectively. A total of five endophytic fungi were isolated, purified and characterized from four seaweeds; Hypnea musciformis (HM), Sargassum crassifolium (SC), Dictyota dichotoma (DD) and Caulerpa peltata (CP). They were coded as HMWE-1, HMWE-2, SCWE-1, DDWE-1 and CPWE-1. The fungal strains HMWE-1 and SCWE-1 were identified morphologically as Fusarium sp., HMWE-2 and DDWE-1 as Penicillium sp. and CPWE-1 as Aspergillus sp. DDWE-1 fungal strain showed significant antioxidant activity in comparison to the standard, ascorbic acid. The fungal extracts CPWE-1 (LC 50 value of 2.85 µg/mL) and DDWE-1 (LC 50 value of 6.38 µg/mL) showed significant cytotoxic activity. The extracts exhibited weak to good activity against a wide range of human pathogenic microorganisms during anti-microbial activity screening. Preliminary chemical screening by thin-layer chromatography (TLC) indicated the presence of a number of secondary metabolites. Thus, this study explored the potential entophytes from marine weeds of the Bay of Bengal as a producer of leads for drugs.
