We investigated which microbial taxa in coastal Red Sea water were stimulated by addition of mucus from the coral Fungia sp. Decreases in the concentration and C/N ratio of particulate organic material during short-term incubations (50 h) were paralleled by a steep rise in the number of Gammaproteobacteria, particularly Alteromonadaceae, followed by Vibrionaceae. Two almost identical genotypes affiliated with Alteromonas macleodii accounted for up to >85% of all Alteromonadaceae (45% of the total cells) in the mucus-amended enrichments but were rare in unamended control incubations and in ambient seawater. A. macleodii-like bacteria might thus be important in the transfer of organic carbon from coral mucus to the pelagic microbial food webs of coral reefs.
