2Seasonal variations of phytoplankton diversity in the Coleroon coastal waters,southeast coast of India显示文摘The results of an investigation carried out during June 2005 to May 2007 on physico-chemical parameters,species composition and community structure of phytoplankton including Chlorophyll a(Chl-a) at the Coleroon coastal waters(Southeast coast of India) are reported.Air and surface water temperatures(°C) varied from 25.1 to 30.1 and from 24.5 to 28.5 respectively.Salinity values varied from 6 to 28.5 and the pH ranged between 7.0 and 8.3.Variation in dissolved oxygen content was from 3.1 to 7.5 mg/dm-3 while the light extinction coefficient values(LEC) ranged between 3.1 and 10.1 cm.The ranges of inorganic nutrients(μmol/dm-3) viz.,nitrate,nitrite,phosphate and silicate were 10.1-23.4,1.2-8.9,0.2-3.1 and 55-125,respectively.The ranges of Chlorophyll a(μg/dm-3) values was 2.0-7.5.Presently,124 phytoplankton species representing different classes viz:Bacillariophyceae(77),Dinophyceae(19),Cyanophyceae(15),Chlorophyceae(10) and Chrysophyceae(3) were recorded.The phytoplankton cell abundance varied from 0.290 to 111.662 cells/cm-3,with peak diversity(3.38 bits/ind.) during summer season.The maximum abundance was found during summer season coinciding with the stable hydrographical conditions.The seasonal distribution and abundance of phytoplankton are discussed in relation to hydrographical parameters.Canonical Correspondence Analysis(CCA) was applied in this paper for discriminating environmental factors having effect on phytoplankton community at species level.Coleroon coastal water is subjected to long term fluctuations in physico-chemical parameters depending upon the seasonal tidal amplitude and freshwater influx resulting in a continuous exchange of organic,inorganic,plant and animal matters.Thillai Rajasekar K Rajkumar M SUN Jun Ashok Prabu V Perumal P 2010Acta Oceanologica Sinica2010,29,5:3
3MICP as a potential sustainable technique to treat or entrap contaminants in the natural environment:A review显示文摘In the last two decades,developments in the area of biomineralization has yielded promising results making it a potentially environmentally friendly technique for a wide range of applications in engineering and wastewater/heavy metal remediation.Microbially Induced Carbonate Precipitation(MICP)has led to numerous patented applications ranging from novel strains and nutrient sources for the precipitation of biominerals.Studies are being constantly published to optimize the process to become a promising,cost effective,ecofriendly approach when compared with the existing traditional remediation technologies which are implemented to solve multiple contamination/pollution issues.Heavy metal pollution still poses a major threat towards compromising the ecosystem.The removal of heavy metals is of high importance due to their recalcitrance and persistence in the environment.In that perspective,this paper reviews the current and most significant discoveries and applications of MICP towards the conversion of heavy metals into heavy metal carbonates and removal of calcium from contaminated media such as polluted water.It is evident from the literature survey that although heavy metal carbonate research is very effective in removal,is still in its early stages but could serve as a solution if the microorganisms are stimulated directly in the heavy metal environment.Adharsh Rajasekar Stephen Wilkinson Charles K.S.Moy 2021Environmental Science and Ecotechnology2021,,2:2
