The external mucus layers of the stony coral Porites astreoides and the soft corals Palythoa sp. and Heteroxenia fuscesens are inhabited by communities of marine heterotrophic bacteria. Population levels of bacteria in coral mucus may be regulated by the self-cleaning behavior of the host. Bacterial populations in coral mucus respond to stresses applied to the host coral by growing to higher population levels in the mucus, indicating that these are populations of viable organisms closely… 

Figures and Tables from this paper

Diversity of culturable bacteria in the mucus of the Red Sea coral Fungia scutaria.
TLDR
This study provides the first evidence of actinomycetes isolated from corals, and the culturable heterotrophic bacterial community of the mucus of this coral is composed mainly of the bacterial groups Gammaproteobacteria, Alphaproteabacteria and of Actinobacteria.
Coral mucus-associated bacterial communities from natural and aquarium environments.
TLDR
Comparisons of surface mucus microbiota of the coral Fungia granulosa from the natural environment with that from individuals maintained in aquaria suggest an adaptation of the mucus bacterial communities to the different conditions.
Bacterial Growth on Coral Mucus
TLDR
The indigenous bacterial population of coral mucus increased from 103 to 108 CFU/ml when incubated at 30°C for 11 h, changing from a heterogeneous community to a Vibrio-dominated population.
Microbial Communities of Coral Surface Mucopolysaccharide Layers
TLDR
Theoretical and observed consequences of environmental changes lead to the disruption of the ‘normal’ communities associated with healthy corals, and changes in the community structure may result in the development of disease.
The role of microorganisms in coral health, disease and evolution
TLDR
Generalization of the coral probiotic hypothesis has led to the hologenome theory of evolution, which proposes the occurrence of a dynamic relationship between symbiotic microorganisms and corals that selects for the coral holobiont that is best suited for the prevailing environmental conditions.
Diversityof culturable bacteria in themucusoftheRedSea coral Fungia scutaria
TLDR
This study provides the first evidence of actinomycetes isolated from corals, and the culturable heterotrophic bacterial community of the mucus of this coral is composed mainly of the bacterial groups Gammaproteobacteria, Alphaproteabacteria and of Actinobacteria.
Bacteria as a Source of Coral Nutrition
TLDR
Hermatypic corals attain a large part of their nutrition from photosynthetic products of the zooxanthellae, which are located in their gastrodermal cell layer, but corals must utilize other particulate matter to gain enough nitrogen and phosphorus to grow.
Carbohydrate composition of mucus from scleractinian corals from the central Red Sea
TLDR
The results suggest the presence of a common set of carbohydrates across a broad range of coral species from geographically diverse environments, highlighting the important role of mucus with regard to coral and reef ecosystem function.
In situ release of coral mucus by Acropora and its influence on the heterotrophic bacteria
TLDR
Bacterial abundance in the seawater-mucus mixture increased significantly and coincided with a decline in DOC concentration, and it is suggested that the coral mucus rich in DOC and phosphate can induce the high bacterial growth.
Antimicrobial Activity of Sponges and Corals
TLDR
Living benthic marine organisms such as sponges and corals need the ability to regulate the bacteria they encounter and to resist microbial colonization and the invasion of potential pathogens in order to prevent possible detrimental effects.

TLDR
Observations on the mucus web-forming coral Porites astreoides from Barbados suggested that sediment capture is at least partly responsible for the apparent denaturation of secreted mucus and the transformation of liquid mucus into particulate detritus.

TLDR
It is suggested that phosphate eutrophication and chronic oil pollution are the major man-made disturbances that interfere with coral colonization of the reef flat at the nature reserve.

TLDR
The first quantitative studies of production on coral reefs showed that productivity on reefs was considerably higher than in surrounding waters, and this high production occurred in spite of nutrient limitation and low productivity of offshore waters.
