“…With univariate analysis, both M. aeruginosa and P. pseudoalcaligenes affected DMS and DMTS (p < 0.01) ( Table 1). Our results indicated that off-flavors of P. pseudoalcaligenes and the decomposition of M. aeruginosa aggravated the production of DMS and DMTS, which can generally in agreement with the variation of off-flavors results and the previous studies (Zhang et al, 2010b). Considering three different temperatures, the concentrations of DMS and DMTS of co-culture system (treatment) during lag phase among 24, 28 and 32°C have no significant differences.…”

“…These phenomena might account for that the death and decay of cyanobacteria blooms is often associated with high concentrations of VOSCs. β-Cyclocitral is considered to be the main off-flavor from cyanobacteria (Harada et al, 2009;Li et al, 2007;Yang et al, 2008), which is released during the growth of Microcystis and the disruption of cell integrity (Zhang et al, 2010b). It looks likely that the production of β-cyclocitral is related to metabolism of M. aeruginosa and bacterium (P. pseudoalcaligenes in our study) is not the origin of β-cyclocitral.…”

“…Off-flavors in water supplies usually originate from volatile organic compounds (VOCs) including 2-methylisoborneol (MIB) (Rosen et al, 1968), geosmin (GEO) (Guttman and van Rijn, 2009), dimethyl sulfide (DMS) (Giger and Schaffner, 1981), methyl thiols, dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS) (Zhang et al, 2010b), β-cyclocitral (Ozaki et al, 2008), ethanethiol (Slater and Blok, 1983), 2-isopropyl-3-methoxypyrazine (Buttery and Ling, 1973) and β-ionone (Höckelmann and Jüttner, 2005). Eutrophic lakes were complicated ecosystems and studies about off-flavors should be discussed in regard to various influencing factors.…”

“…3c). Cyanobacteria blooms in Lake Taihu caused a water crisis in 2007 (Guo, 2007;Yang et al, 2008;Qin et al, 2010;Zhang et al, 2010;Qin et al, 2013), which was closely related to continuous enrichment of nutrients (both N and P). From 2009 to 2011, Chl-a gradually dropped (annual average of 7.68 μg L -1 ), which may have been caused by the reduction of external pollution and related recovery measures in the lake.…”

Lake Taihu has undergone severe eutrophication in the past three decades, and harmful cyanobacteria blooms occur nearly every year in Meiliang Bay at the north end of the lake. To elucidate the potential relationship between seasonal nutrient limitation and phytoplankton proliferation, a 20-year (1992-2011) Chl-a throughout 1996. This study suggests that seasonal patterns of nutrient limitation must be considered to develop effective management measures to control cyanobacterial blooms. initial patterns were restored by environmental regulation in the end of 1990s, including the Zero Actions plan. Using routine monitoring data, a generalised additive model (GAM) with time and deviations between trophic state indexes for nitrogen and phosphorus (TSIN-TSIP) as explanatory variables was used to explore which nutrient was responsible for limitation of phytoplankton chlorophyll-a (Chl-a) in different seasons. Surprisingly, the model revealed a weak N limitation (TSIN-TSIP=-10) corresponded to peak values of Chl-a in summer-autumn season, which is probably because the phytoplankton community is co-limited by N and P during the period. The shift of nutrition limitation during winter-spring would partially explain high values of

“…With the deterioration of water quality, eutrophication and cyanobacterial blooms (Microcystis aeruginosa) have frequently occurred, resulting in a significant decrease in ecological service functions. In particular, in late May 2007, massive cyanobacterial blooms accumulated around the drinking water source of Wuxi City, China, and cut off drinking water supplies to approximately 2 million local residents for 1 week , Yang et al 2008, Zhang et al 2010b). The 2007 Wuxi Water Crisis was a particularly serious environment pollution event that was even discussed in a World Bank report (The World Bank 2010).…”

Lake Taihu, as the important drinking water source of the Yangtze River Delta urban agglomeration and the third largest freshwater lake in China, has experienced serious lake eutrophication and water quality deterioration in the past three decades. Growing scientific, political, and public attention has been given to the water quality of Lake Taihu. This study aimed to conduct a comparative quantitative and qualitative analysis of the development, current hotspots, and future directions of Lake Taihu research using a bibliometric analysis of eight well-studied lakes (Lake Taihu, Lake Baikal, Lake Biwa, Lake Erie, Lake Michigan, Lake Ontario, Lake Superior and Lake Victoria) around the world based on the Science Citation Index (SCI) database. A total of 1582 papers discussing Lake Taihu research were published in 322 journals in the past three decades. However, the first paper about Lake Taihu research was not found in the SCI database until 1989, and there were only zero, one, or two papers each year from 1989 to 1995. There had been rapid development in Lake Taihu research since 1996 and a sharp increase in papers since 2005. A keyword analysis showed that "sediment," "eutrophication", "Microcystis aeruginosa", "cyanobacterial blooms", and "remote sensing" were the most frequently used keywords of the study subject. Owing to its significant impact on aquatic ecosystems, a crucial emphasis has been placed on climate change recently. In addition, the future focuses of research directions, including (1) environmental effects of physical processes; (2) nutrient cycles and control and ecosystem responses; (3) cyanobacteria bloom monitoring, causes, forecast and management; (4) eutrophication and climate change interactions; and (5) ecosystem degradation mechanism and ecological practice of lake restoration, are presented based on the keyword analysis. Through multidisciplinary fields (physics, chemistry, and biology) cross and synthesis study of Lake Taihu, the development of shallow lake limnology will be largely promoted.
