21. Perspectives on Biofilms for the Removal of Organic Micropollutants in Wastewater
Abstract : The use of biofilms to improve the removal of organic micropollutants in waste¬water treatment plants (WWTPs) has been investigated. The work is divided into two parts. In the first part, the use of biofilms for the biological degradation of micro¬pollutants was investigated. READ MORE

22. Removal of Organic Micropollutants from Wastewater in Biofilm Systems
Abstract : The presence of organic hazardous substances in the aquatic environment, such as pharmaceutically active compounds and personal care products, has become a worldwide issue of increasing environmental concern. Present at concentration of nano- to milligram per liter, they are defined as organic micropollutants (OMPs). READ MORE

23. Microbial communities in anammox and nitrifying biofilms
Abstract : Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. READ MORE

24. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles
Abstract : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. READ MORE

25. Distribution and Biogeochemical Cycling of Arsenic In Grey and Brown Sand Aquifers in the Bengal Delta Plains (India)
Abstract : An elevated level of Arsenic (As) in aquifers from India and Bangladesh affecting the human health has been widely reported since the late 1980s. The thesis aim is to investigate the present status of As contamination and biogeochemical cycling with direct role of diverse indigenous bacterial communities in As cycling in the Bengal Delta Plain (BDP) aquifers in Nadia district, West Bengal (India).
