| 1 | Bacteria as indicators for finding oil and gas reservoirs:A case study of the Bikaner-Nagaur Basin,Rajasthan,India显示文摘Geo-microbial prospecting for hydrocarbons is an exploration method based on the seepage of light gaseous hydrocarbons from oil/gas reservoirs to the surface and their utilization by hydrocarbon oxidizing bacteria.These bacteria utilize hydrocarbon gases as their sole source of food and are found to be enriched in the near surface soils/sediments above the oil and gas reservoirs.The detection of anomalous populations of n-pentane and n-hexane oxidizing bacteria in the surface soils can help to evaluate the prospects for hydrocarbon exploration.A geo-microbial survey has been carried out in the Bikaner Nagaur basin to investigate the prospects for hydrocarbon exploration.In the present study,bacterial counts for n-pentane utilizing bacteria range between 2.0×10 2 and 1.26×10 6 cfu/gm and n-hexane utilizing bacteria range between 2.0×10 2 and 1.21×10 6 cfu/gm.The bacterial concentration distribution maps show four distinct anomalies in the study area.The possibility of discovering oil or gas reservoirs using the microbiological method is emphasized by the fact that the hydrocarbon-oxidizing bacteria range between 10 3 and 10 6 cfu/gm in soil/sediment receiving hydrocarbon micro-seepages.In the present study area of the Bikaner Nagaur basin,n-pentane and n-hexane utilizing bacteria are found between 10 5 and 10 6 cfu/gm of soil sample,which is significant and thereby substantiates the seepage of lighter hydrocarbon accumulations from oil and gas reservoirs.Geo-microbial prospecting studies suggest that hydrocarbon micro-seepage of subsurface origin is present in the study area and indicate that the area has positive prospects for petroleum exploration. | Mohammed Abdul Rasheed Mutnuri Lakshmi Deshoju Srinu Anurodh Mohan Dayal | 2011 | Petroleum Science2011，8，3： | 3 |
| 2 | Probing the degradation of pharmaceuticals in urine using MFC and studying their removal efficiency by UPLC-MS/MS显示文摘Nutrient recovery from source-separated human urine has attracted interest as it is rich in nitrogen and phosphorus that can be utilized as fertilizer.However,urine also contains pharmaceuticals,steroid hormones,etc.and their removal is crucial as they have detrimental effects on the environment and human health.The current study focuses on investigating the degradation of pharmaceuticals using a double-chamber microbial fuel cell(MFC).Urine was spiked with four pharmaceuticals(trimethoprim,lamivudine,levofloxacin,and estrone)at a concentration of 2 mg/mL.The MFC was operated for 7 months in batch mode with this spiked urine as feed.The degradation efficiency of the MFC was studied,for which a selective liquid chromatography-tandem mass-spectrometric method was developed for the quantitation of compounds used in the spiking experiments and was validated with a lower limit of quantification of 0.39 ng/mL.The maximum removal rate achieved was 96%±2%.The degradation mechanism involved processes like sorption and anoxic biodegradation.The voltage curve obtained showed that the presence of pharmaceuticals had an initial negative impact on power generation along with increased organic content;however,after the reactor acclimatization,increased power output was achieved with maximum organics removal at 30 h of retention time.This work opens a new perspective for the anoxic biodegradation of pharmaceuticals and can be useful in future bioremediation studies. | Priya Sharma Devendra Kumar Srikanth Mutnuri | 2021 | Journal of Pharmaceutical Analysis2021，11，3： | 2 |
