Microcystins (MC) and nodularin (NOD) are common contaminants of drinking water around the world due to their significant health impact it is important explore suitable approaches for removal. Unfortunately, these toxins not always removed by conventional treatments. One most exciting areas that hold promise a successful cost effective solution bioremediation microcystins. Recent work resulted in isolation characterisation 10 novel bacterial strains (Rhodococcus sp., Arthrobacter spp....

Studies on Harmful Algae (HA) are rare in the Indian Ocean around Sri Lanka. The current study investigated diatoms and dinoflagellates five Lankan Southern coast locations, focusing potentially harmful species. A total of twenty-seven diatom species ten dinoflagellate were identified during study. Among them, eight (Asterionellopsis glacialis, Chaetoceros curvisetus, lorenzianus, Guinardia flaccida, Leptocylindrus minimus, Nitzschia sp., Proboscia alata Pseudonitzschia fraudulenta) three...

Better understanding of the mechanisms hydrocarbon degrading microorganisms and effect some environmental factors is critical for optimisation bioremediation processes. Temperature, pH, nitrate phosphate are major that influence there mediation process bacterium. In present study, optimisations selected physico-chemical parameters (temperature, phosphate) were carried out on Bacillus cereus, Enterobacter sp. ludwigii which previously isolated as potential oil degraders. The bacteria showed...
Harmful cyanobacterial (blue-green algae) blooms, are common in eutrophic waters. Certainbloom forming species such as Microcystis, Anabaena, Nostoc and Planktothrix/Oscillatoriaare a serious threat to water quality due the potent toxins production. Microcystins, thecyclic heptapeptides produced by cyanobacteria, hepatotoxic tumor-promoting;inhibit protein phosphatases types 1 2A. WHO established recommended level of μg/lfor most hazardous Microcystin-LR (MC-LR) for drinking water....
Microcystin-LR (MC-LR) is a cyanotoxin produced by certain cyanobacteria species. It toxic to humans and animals. Several studies have demonstrated that cyanotoxins accumulate throughout the food chain, eventually reaching high levels in freshwater fish. The Nile tilapia (Oreochromis niloticus) most popular fish Sri Lanka Asian countries. current study sought determine MC-LR concentration collected from thirteen reservoirs; Nallachchiya, Galkulama, Anakattiya, Padaviya, Nachchaduwa Kalawewa...
Cylindrospermopsin (CYN) is a cyanotoxin found in natural waters, with potential risk to human health through the inhibition of protein synthesis. Despite implementation conventional water treatment procedures, complete removal CYN remains question due its heat-stable nature. Hence, contamination sources challenge providing safe drinking throughout world. The present study was conducted test ability degrade at 280C and pH 7, four bacterial strains: Bacillus cereus-Y, cereus-S (B. cereus-S),...
Naturally derived cyanotoxins, cylindrospermopsin (CYN), and microcystin-LR (MC-LR) have shown hepatotoxic nephrotoxic effects in several studies. The present study aimed to determine the possible nephrotoxicity of MC-LR CYN on mammalian kidneys using male Wistar rats as an animal model. Potential was evaluated at different doses (0.175 μg.kg-1, 0.140 0.105 μg.kg-1) (0.105 0.070 0.035 observed.

Cyanobacteria are photosynthetic bacteria found naturally in lakes, streams, ponds, andreservoirs. Microcystis aeruginosa, Anabaena sp., Nostoc Oscillatoria sp. someharmful cyanobacteria that produce cyanotoxins. Microcystin-LR (MC-LR) is the dominanttype of cyanotoxin produced by these cyanobacteria. MC-LR causes hepatotoxic effect onhuman beings and harmful to animals as well. Therefore, World Health Organisation(WHO) has recommended a guideline value less than 1 μg/l should be presentin...

Cyanotoxins, Microcystin LR (MC-LR) and Cylindrospermopsin (CYN) are hepato nephro toxins considered as one of the hypotheses for Chronic Kidney Disease Unknown Etiology (CKDu) in Sri Lanka. Recent studies have revealed that significant number dug wells North Central Uva provinces where CKDu is prevalent contaminated with cyanotoxins MC-LR CYN. In present study, cyanotoxin; MC-LR, CYN, potential toxin-producing cyanobacteria were studied 330 9 spring water samples collected from high areas...
Microcystins are a diverse group of hepatotoxic secondary metabolites produced bycyanobacteria (blue-green algae). Up to date more than 90 different wereidentified. Among them, Microcystin-LR (MC-LR) is one the most toxic and mostcommonly encountered Microcystin variants worldwide. Although detection extractionmethods for have been previously reported, there no such techniquesavailable in Sri Lanka regarding water safety monitoring. Therefore this study, we aimto develop an efficient...
