“…Certain species of cyanobacteria are known to be responsible for the occurrence of off-flavor compounds (2-methylisoborneol (MIB), geosmin and b-cyclocitral) in water bodies, including species from the genera Oscillatoria (Matsumoto and Tsuchiya, 1988), Anabaena (Rosen et al, 1992), Microcystis (Jü ttner et al, 2010), Phormidium (Izaguirre, 1992), Lyngbya (Schrader and Blevins, 1993), and Pseudanabaena (Izaguirre and Taylor, 1998), imparting an undesirable earthy, musty, or muddy flavor to the fish.…”

“…The previous studies revealed that there was strain specificity in the ability of actinomycetes to produce odorous (Yagi et al 1987;Aoyama 1990;Schrader & Blevins 1993). In this study, Streptomyces, Micromonospora and Actinomadura, which are typical actinomycetes associated with odorous compounds, were all found in Tianjin fishponds (Gerber 1968(Gerber , 1969Wood et al 1983).…”

The presence of the odorous compounds, 2-methylisoborneol (MIB) and geosmin, as well as causative microorganisms in brackish intensive cultivation fishponds in Tianjin, China that had a severe earthy-musty odor were evaluated. The results revealed that MIB was the primary odorous compound present in the Tianjin fishponds, with a concentration ranging from 0.53-5302.7 ng·L 21. Furthermore, the concentration of MIB was found to be closely correlated with the gross biomass of actinomycetes in the water, which ranged from 10.67-1528.24 £ 10 6 cfu·ml 21. Therefore, the sequences of the 16 SrRNA and morphological characteristics of the actinomycetes in the brackish fishponds were investigated. The results revealed that the actinomycetes in the brackish fishponds included 9 species of common and dominant actinomycetes belonging to 4 genera. Of these genera, Streptomyces were the dominant species, and Streptomyces, Nocardioides and Micromonospora were the most common species in the fishponds evaluated. Next, the ability of each of the isolated Streptomyces to produce MIB was measured under laboratory culture conditions. Streptomyces Sp2 was found to have a strong ability to produce MIB, which indicates that this strain may be the primary source of the earthy-musty odor reported in brackish intensive cultivation fishponds in Tianjin, China.

“…Morphological and phylogenetic analysis revealed that UIC 10445 was closely related to strains previously identified as Lyngbya wollei , a known producer of the neurotoxic saxitoxins, as well as the odor compounds geosmin and 2-methylisoborneol. (Carmichael et al, 1997; Foss et al, 2012; Schrader and Blevins, 1993; Watson et al, 2008) Recently, strains belong to the group of Lyngbya wollei were considered to form a separate genus described as Microseira . (McGregor and Sendall, 2015) Thus, UIC 10445 was identified as a Microseira sp.…”

Microseiramide (1), a cyclic heptapeptide, was isolated from a sample of the freshwater cyanobacterium Microseira sp. UIC 10445 collected in a shallow lake in Northern Indiana. Taxonomic identification of UIC 10445 was performed by a combination of morphological and phylogenetic characterization. Phylogenetic analysis revealed that UIC 10445 was a member of the recently described genus Microseira, which is phylogenetically distinct from the morphologically similar genera. Moorea and Lyngbya. The planar structure of microseiramide (1) was determined by extensive 1D and 2D NMR experiments as well as HRESIMS analysis. The absolute configurations of amino acid residues were determined using acid hydrolysis followed by the advanced Marfey's analysis. microseiramide (1) is the first cyclic peptide reported from a Microseira sp., and the structure of microseiramide (1) is distinct from the previously known metabolites from cyanobacteria of the genera Moorea and Lyngbya.
