“…Temperate cyanobacteria produce a range of natural toxins collectively known as cyanotoxins (Quiblier et al 2013;Moreira et al 2014), whose production may be directly influenced by environmental conditions (Neilan et al 2013). However, very little is known regarding the toxins produced by cyanobacteria in Arctic and Antarctic lakes, ponds or even terrestrial environments.…”

Polar Regions (continental Antarctica and the Arctic) are characterized by a range of extreme environmental conditions, which impose severe pressures on biological life. Polar cold-active cyanobacteria are uniquely adapted to withstand the environmental conditions of the high latitudes. These adaptations include high ultra-violet radiation and desiccation tolerance, and mechanisms to protect cells from freeze-thaw damage. As the most widely distributed photoautotrophs in these regions, cyanobacteria are likely the dominant contributors of critically essential ecosystem services, particularly carbon and nitrogen turnover in terrestrial polar habitats. These habitats include soils, permafrost, cryptic niches (including biological soil crusts, hypoliths and endoliths), ice and snow, and a range of aquatic habitats. Here we review current literature on the ecology, and the functional role played by cyanobacteria in various Arctic and Antarctic environments. We focus on the ecological importance of cyanobacterial communities in Polar Regions and assess what is known regarding the toxins they produce. We also review the responses and adaptations of cyanobacteria to extreme environments.

“…Most previous studies addressing T&O have thus mainly focused on eutrophic water bodies as the blooming of cyanobacteria is usually associated with nutrient-rich water bodies (Yang et al, 2008;Paerl and Huisman, 2008;Adam et al, 2011;Naselli-Flores, 2011;Brookes and Carey, 2011). However, the occurrence of odors produced by benthic or low irradiance specialist cyanobacteria is also frequently reported in drinking water reservoirs which are in a mesotrophic or even oligotrophic state (Mez et al, 1998;Wood et al, 2012;Catherine et al, 2013). Oligotrophic conditions limit the growth of the surface living cyanobacteria, resulting in high water transparency, which is vital for the growth of the deep living and benthic cyanobacteria (Scott and Marcarelli, 2012;Catherine et al, 2013).…”

Abstract-In this study, the TiO 2 immobilized on fiberglass cloth was prepared to improve the photocatalytic activity of TiO 2 and overcome the difficulty of reuse through painting followed by sol-gel process. The morphology and microstructure of TiO 2 loaded on FGC were characterized via XRD and SEM, respectively. The result revealed that 1) the crystalline structure of immobilized TiO 2 was nearly unchanged compared with pure P25 nanoparticles. 2) The TiO 2 loaded on FGC had larger specific surface area than that of P25. 3) The TiO 2 /FGC system displayed remarkable photocatalytic activity on decomposition of MC-LR.Index Terms-TiO 2 , fiberglass cloth, MC-LR, photocatalytic performance.
