Also, representatives of other groups of Actinobacteria found in this study, namely the genera Micrococcus (Bultel-Ponce et al., 1998), Curtobacterium (Firakova et al., 2007) and Propionibacterium are

known as producers of pharmaceutically important antibiotics. More attention should be paid to these ecological species, though further scientific evidence needs to be produced to verify the symbiotic or commensal relationship between these actinomycetes and their coral hosts. The isolation of several actinomycetes in this study, which might possibly be novel species, can be targeted for antimicrobials. In parallel to coral Palbociclib price mucus, the coral tissue, which is also colonized by a dynamic microbiota (Rohwer et al., 2001), like the sponge tissue can also be

targeted for the isolation of actinomycetes and screened for antimicrobials as Geffen et al. (2009) hypothesize that coral antibacterial activity is produced and stored in the corals’ tissue. In addition, variation in culture conditions like cultivating the actinomycetes on substrate surfaces or in liquid broth, cocultivation with other microorganisms and investigating the phenomenon of quorum sensing in antibiotic production can influence the production of secondary metabolites (Yan et al., 2003; Diggle et al., 2007), which will unravel the biotechnological potential of these isolates.

“Scientists, educators, and students benefit from having free and centralized access to the wealth CHIR-99021 mouse of metabolic information that has been gathered over the decades. Curators of the MetaCyc database work to present this information in an easily understandable pathway-based framework. MetaCyc is used not only as an encyclopedic resource for metabolic information but also as a template for the pathway prediction software that generates pathway/genome databases for thousands of organisms with sequenced genomes (available at www.biocyc.org). Curators need to define pathway boundaries and classify pathways within a broader pathway ontology to maximize the utility of the pathways to both users and the pathway prediction software. These seemingly simple tasks pose several challenges.
