Diversity of Coral Eunicea fusca Associated Bacteria Using Culture Dependent Techniques
Abdelnasser S.S. Ibrahim

Abstract: Invertebrates are known to be associated with diverse bacterial population, however, very little is known about the structure, composition and maintenance of these bacterial communities. In the current study, we characterize the culturable bacterial community associated with gorgorian coral Eunicea fusca. This was achieved using culture-based methods and molecular techniques for the identification of the bacterial isolates. The culturable heterotrophic bacterial community of this coral is composed mainly of the bacterial groups Alphaproteobacteria (65.5%), Gammaproteobacteria (20.7%), Betaproteobacteria (6.9%), Cytophaga-Flexibacter Bacteroids (3.4%) and Firmicutes (3.4%). This study provides evidence of specific bacterial association with the coral in comparison to bacterial community in the coral surrounding seawater. Furthermore, bacterial isolation using oligotrophic conditions,. at slightly alkaline pH, was found to increase the culturability and diversity of Eunicea fusca associated bacteria.
