In the current economy, finding solutions to cut water consumption while reducing the expense of fertilizer has caught the interest of the agricultural industry, lawn care professionals, homeowners and gardeners across the country. Even though the rising cost of water garners little attention in the news, water prices have doubled and tripled in ...

Paralytic shellfish toxins are secondary metabolites produced by several species of dinoflagellates and cyanobacteria. Known targets of these toxins, which typically occur at detrimental concentrations during harmful algal blooms, include voltage‐gated ion channels in humans and mammals. However, the effects of the toxins on the co‐occurring ...

The process of reservoir eutrophication has been recognised as a central problem in tropical reservoir environmental quality. Effects of eutrophication are complex interactions involving a decrease in water quality, especially loss of aquatic biodiversity, occurrence of undesired species such as cyanobacteria with its cyanotoxins, mass ...

The aim of this work was to isolate a photosynthetic Microbial Consortium (MC) with capacity to fix nitrogen, from biological material collected in a rice field. The isolated MC was maintained at BG–110 medium, free of nitrogen source and progressively scaled up at 0.5 L, 1 L, 1.9 L and 11 L working volume. The nitrogen fixing rates obtained in ...

For the Ministry of Agriculture in Cyprus, LG Sound b.v installed 33 LG Sonic, ultrasonic devices in the Limassol water treatment plant, to prevent bad odour and taste to the water caused by geosmins in the water. The earthy taste problem persisted during summer of 2010 and various physical, chemical and biological tests were done in order to ...

Algae Enumeration and Identification Algae are ubiquitous in virtually all aquatic environments and are important bioindicators of water quality. They are frequently used to assess and monitor the health of aquatic systems. On the other hand, they are also responsible for imparting undesirable flavors to potable water supplies and pose potential ...

Oxygen conditions in the south eastern Baltic have improved thanks to an inflow of oxygen-rich water from the North Sea during November/December 2011. This inflow has also caused the concentrations of phosphate and silicate to increase in the surface waters, which could cause excessive algal blooms this summer. As a result of the relatively large ...

In summer, Cyanobacteria, Chlorococcalesa and Diatom occupy 99% of total phytoplankton biomass in Taihu Lake, China. Nitrogen plays an important role toward shaping that structure of phytoplankton. Three typical species were chosen to investigate the competing relationship among those three phylum by the nitrate dynamic experiments and supply ...

Possibilities & Expectations of the LG Sonic for cooling tower treatment: LG Sonic devices control the bacterial population in cooling tower systems by severely inhibiting biofilm formation. This provides a large market potential in cooling water treatment applications. It is well known that Legionella bacteria propagate by reproducing ...
