Aims
Geosmin is associated with off‐flavour problems in recirculating aquaculture systems (RAS) and represents an economic problem for the aquaculture industry. This study aims at investigating factors influencing the composition of the bacterial microbiota, in particular the presence of geosmin producers and the environmental and farming factors favouring geosmin accumulation.
Methods and Results...
Earthy off-flavour, caused by geosmin, constitutes an economic problem in recirculating aquaculture systems (RAS). Cyanobacteria, Streptomyces and myxobacteria are thought to be the main geosmin-producing bacteria in aquatic systems. In this study, the phylogeny of the gene involved in the geosmin production, geosmin synthase gene (geoA), was investigated. The results revealed an absence of multiple...
