A  study  was  conducted  to  determine  the  suitability  of  groundwater  used  for  irrigation  in  and  around  the Bhopalpatnam  area  of  Bijapur District, Chhattisgarh,  during pre-and post-monsoon seasons of 2016. In this study, sixty two groundwater samples were collected different villages and analyzed for various hydrochemical parameters like pH, EC, Alkalinity, Hardness , TDS, Ca, Mg, Na, K, CO3, HCO3, Cl, SO4, NO3, PO4, Fe and F. Physico-chemical characterization of the samples revealed that groundwater from  most  of  the  sources  was  not  fit  for  drinking owing  to  a  high  concentration  of  EC, HCO3, NO3, Fe and F. Irrigation indices such as Sodium adsorption ratio (SAR), Sodium percentage (Na %), Residual sodium carbonate (RSC), Permeability Index (PI), Kelly's Ratio (KR), Magnesium Hazard (MH) and EC were also calculated. The SAR values obtained for all the samples were plotted against EC values in the US Salinity Laboratory diagram and it was revealed that the most of the samples fall under water type C3-S1 indicating high salinity and low SAR. The  analysis  of  the  various  parameters  indicated  the  moderate  suitability  of groundwater for irrigation purpose. Keywords : Groundwater, Irrigation, SAR, %Na, KR, PI and MH.

Metal Tolerant Bacteria

Heavy metals pollution is emerging as a threat to ecological systems causing various problems to mankind, plants and animals. Aim of the present study was to isolate and identify cadmium tolerant bacteria from the soil of Wazirpur industrial area of New Delhi (India). The study involved physico-chemical characterization of the polluted soil which was found to contain high concentration of iron, manganese and cadmium at 352, 15.3 g/kg soil and 3.16 ppm, respectively. One bacterial strain was identified as Sporosarcina luteola on the basis of morphological, biochemical and phylogeny analysis. Strain Sporosarcina luteola was highly resistant to Cd up to 5mM (mM= millimolar) when cultured in solidified nutrient agar plates and 7.2 mM in nutrient broth. Sporosarcina luteola has also showed substantial growth in presence of Co, Pb, Fe and Mn upto 2.0, 2.0, 3.5 and 4.0 mM, respectively in liquid medium. Optimum growth of identified bacteria was shown at 37 ºC, 7.0 pH and it tolerated up to 3 % sodium chloride (w/v). This is reported for the first time that Sporosarcina luteola (metal-tolerant bacteria) has potential of removal of cadmium from industrially contaminated soil.

Double Hydroxides

The fourth generation cephalosporin antibacterial agent, cefepime, was loaded into layered double hydroxides for enhancing antibiotic efficiency, reducing side effects, as well as achieving the sustained release property. The intercalation of antibiotic into the inter-gallery of ZnAl-layered double hydroxide (LDH) was carried out using ion exchange method, by this constituting a nano-sized organic-inorganic hybrid material for a controlled release novel formulation. Although cefepime is a broad spectrum antibiotic, it has various adverse effects and a significant degradation rate. Thus, the preparation and physico-chemical characterization of nanomaterials able to intercalate this drug is an important study for medical and pharmaceutical field. The antibiotic inclusion into LDHs nanostructure was confirmed by advanced characterization techniques and the release profile of cefepime was analysed with the respect to pH of the simulated media.
