Other off-flavor compounds of microbial origin have been isolated and identified from cultured fish and drinking water supplies. p-Cyclocitral has a tobacco-like odor and has been isolated from blooms of the cyanobacterium Microcystis spp. [24] and the flesh of farm-raised channel catfish [25]. P-Cyclocitral does not appear to be a large off-flavor problem in aquaculture [18]. Isopropylmercaptan, a compound with an oniony odor, has been isolated from cultures of Microcystis sp. [26], and 1 -octen-3-one, a mushroom-like odor-producing compound, has been isolated from cultures of an Anabaena sp. [27]. In addition, offensive sulfur-containing compounds are released into the water during cyanobacterial cell decomposition [26,28],...
