  • Studies on adsorptive removal of toxicants from water

    • Authors: Anuradha Baghel; Beer - Singh
      Abstract: The objective of our study was to develop and explore the appropriate adsorbents for the removal of toxicants such as heavy metals, CN¯, E. coli, and chemical warfare agents (nerve agents and sulphur mustard) from water. The presence of toxicants in drinking water causes severe threats for living beings. Therefore, many adsorbents such as activated carbon, impregnated carbon, activated carbon spheres, bentonite loaded fabric strips, ion exchange resins, and molecularly imprinted polymers were studied for the elimination of toxicants dissolved in water. Out of them activated carbon and impregnated carbons are highly porous material and having high surface area in comparison to others while molecularly imprinted polymers show high selectivity towards imprinted ions. Stirring time, adsorbent amount and initial concentration of toxicants also affect their removal from water. Pb(II) adsorption on carbon obeyed first order in starting then followed pseudo second order kinetics. While SM adsorption on carbon from a mixture of methanolic water (1 : 1) was  pseudo first order with 5.04 X 10–3 min-1 rate constant and half life of adsorption reaction was 137.5 minutes. .

  • Studies on decontamination of toxic chemical using nanoporous materials

    • Authors: J. Praveen Kumar; Gangavarapu Krishna Prasad, B Singh
      Abstract: Objective of our study was to explore and evaluate the novel and alternative reactive sorbent decontaminants based on nanoporous materials to the existing ones such as fuller’s earth for the use in personal decontamination kits and spray devices against chemical weapons. Nanoporous materials have exceptional capacity to adsorb wide range of chemical weapons on their large internal as well as external surface and also in the nanometer sized pore space. They can be spread or sprayed on contaminated surfaces to help in decontamination by adsorptive removal of chemical weapons. After adsorption, they participate in chemical reactions with chemical weapons and decontaminate them owing to the wealth of active sites on their surface. Subsequently, after wiping off the used reactive sorbent decontaminant the surfaces are rendered safe for normal operations.

  • Studies on adsorption of toxic chemicals on carbons

    • Authors: Gangavarapu Krishna Prasad; Beer Singh
      Abstract: Filtration systems containing impregnated carbons have been used for the removal of persistent as well as non persistent chemical warfare agents from the contaminated air in order to provide breathable air to the user. Non persistent chemical warfare agents are removed by filtration systems by means of chemical reactions, however, persistent chemical warfare agents are removed by mainly physical adsorption. Once the life of filtration is consumed, its disposal and handling becomes more important and raises concerns over safety. There shall be cross contamination due to desorption when it is disposed off improperly after its use. To overcome these problems a suitable carbon with the efficient capability to take part in in situ degradation of physisorbed toxic chemicals becomes indispensible. To meet this requirement, a study was undertaken to develop suitable reactive carbon for in situ degradation of sulphur mustard when used in nuclear, biological, and chemical filtration systems.

  • An integrated study on the biological treatment of NO3-N Laden Aquaculture

    • Authors: Valsa Remony Manoj
      Abstract: Sustainable Aquaculture development in India warrants Environmentally Sustainable Recirculating aquaculture systems which can lower environmental impact and conserve water. However, such technologies are not popular since majority of brackishwater shrimp aquaculture is still practiced as   semi-intensive  enterprise.  An important challenge in biological aquaculture wastewater treatment in recirculating units is accumulation of nitrate nitrogen of upto 500 mg/L, which is reported to be  toxic  to  fish  at  levels  of  20  mg  of  NO3 -N/L.  Biological denitrification  using  attached  growth  is  a suitable method; but is in want of cheaper materials to be used as bacterial support medium.  The present study evaluated indigenously available coconut  coir  fibre  compared to commercially available synthetic Fujino spirals for denitrification of nitrate laden synthetic aquaculture wastewater in upflow  anaerobic  packed  bed  column  bioreactors. In  the  experiments,  maximum  nitrate  removal  (99%)  was  achieved using  coconut coir  fibre  as  the  bacterial  support  medium. The performance of coconut coir fibre was comparable to that of Fujino spirals. Physical and biochemical tests results further compounded  it’s  resilience , structural integrity. PCR analysis confirmed presence of Denitrifying genes. Subsequent application of support medium with coconut coir fibre anaerobic baffled reactor obtained maximum COD  removal  of  96  %  and  95  % . Post aeration using cascading method removed residual ammonia and restored  dissolved oxygen. A  conceptual  model  for  the  integration  of  anaerobic  and  aerobic  processes  in  the  treatment  of  nitrate  laden  aquaculture  wastewater  has  been developed based on the findings.

  • Studies on photocatalytic decontamination of toxic chemicals and
           micro-organisms using nanomaterials

    • Authors: Ramacharyulu V R K Peesapati; G.K. Prasad, K. Dwivedi
      Abstract: Objective of this study was to develop an advanced sorbent decontamination system for the cleansing of surfaces contaminated with chemical, and biological warfare agents. This study employs conventional energy sources like natural sunlight, and a nontoxic solid based on nano titania. The catalyst is intended to be sprayed on the contaminated surfaces, which adsorbs toxic chemicals due to higher surface area. After adsorption, the toxic chemical undergoes photocatalytic degradation on the surface of nano titiania in the presence of ecological sunlight and was degraded into non-toxic products. Resultant sorbent is wiped off to obtain cleaned surfaces.

  • Proteomic and metabolic analysis of chemolithotrophic bacteria for
           sequestration of carbon dioxide and production of biodiesel

    • Authors: Randhir Kumar Bharti
      Abstract: A chemolithotrophic bacterium enriched in the chemostat in presence of sodium bicarbonate as sole carbon source was identified as Serratia sp. ISTD04 by 16S rRNA sequencing. The bacterium was tested for product formation in form of calcite crystals in presence of 5% CO2. Carbon dioxide sequestering capacity of bacterium was detected by 14C labeling and purification of carbonic anhydrase enzyme and RuBisCO. 14C labeling analysis revealed that the rate of assimilation of CO2 by the strain is 0.756 x 10-9 μmol CO2 fixed cell-1 h-1. Whole cell soluble proteins of Serratia sp. grown under autotrophic and heterotrophic conditions were resolved by two-dimensional gel electrophoresis and MALDI-TOF/MS for differential expression of proteins. In proteomic analysis of 63 protein spots, 48 spots were significantly up-regulated in the autotrophically grown cells; seven enzymes showed its utilization in autotrophic carbon fixation pathways and other metabolic activities of bacterium including lipid metabolisms indicated sequestration potency of carbon dioxide and production of biomaterials. The bacterium produced 0.647 mg mg-1 per unit cell dry weight of lipids. After transesterification of lipids, the total saturated and unsaturated FAME was found to be 51% and 49% respectively. The major FAME contained in the biodiesel was C16:0, C18:1 and C19:1.

  • Expression of Insecticidal Toxin Coded by Modified Full-Length and
           Truncated Bt-cry1Ac Gene in Transgenic Tomato for Assessment of Their
           Stability and Efficacy against Target Insects.

    • Authors: Bhupendra Koul; Devendra V. Amla, Indraneel Sanyal
      Abstract: The work is structured into four different parts. The first part is dedicated to computational analysis of six variants of Bt-cry1A genes to generate an idea of their integrity and stability. The second part includes optimization of Agrobacterium-mediated tomato transformation procedure using vegetative leaf disc-explants with p35SGUS-INT and validation of the procedure using five different genes of diverse origin. The third part deals with a comparative analysis of constitutive promoter DECaMV35S and synthetic promoter Pcec (complete expression cassette) with defined regulatory sequences to enhance the expression and efficacy of Bt-cry1Ac gene against Helicoverpa armigera in transgenic tomato. Finally, the fourth part discusses molecular characterization and comparative expression analysis of transgenic tomato transformed with modified full-length and truncated version of cry1Ac genes. It also includes the performance and efficacy of truncated cry1Ab gene against Helicoverpa armigera and Spodoptera litura, in transgenic tomato. The higher level of Cry1Ab toxin (≈ 0.47 ± 0.01% TSP) did not show any detrimental effect on in vitro regeneration, plant development and efficacy against target pests in transgenic line Ab25E, contrary to the  earlier reports with Cry1Ac toxin. The full-length cry1Ac gene can be redesigned for higher expression and performance in dicots.
