genetic potential for secondary metabolite production in stromatolite communities.the cyanobacterial communities associated with stromatolites surviving in extreme habitats are a potentially rich source of bioactive secondary metabolites. we screened for the potential for production of bioactive metabolites in diverse species of cyanobacteria isolated from stromatolites in hamelin pool, shark bay, australia. using degenerate primer sets, putative peptide synthetase and polyketide synthase genes were detected from strains of symploca, leptolyngybya, microcoleus, pleuorocapsa, ...200515668032
microbial diversity of extant stromatolites in the hypersaline marine environment of shark bay, australia.stromatolites have been present on earth, at various levels of distribution and diversity, for more than 3 billion years. today, the best examples of stromatolites forming in hypersaline marine environments are in hamelin pool at shark bay, western australia. despite their evolutionary significance, little is known about their associated microbial communities. using a polyphasic approach of culture-dependent and culture-independent methods, we report the discovery of a wide range of microorganis ...200415344935
