A one-year study was performed at the Vavihill background station in southern Sweden to estimate the anthropogenic contribution to the carbonaceous aerosol. Weekly samples of the particulate matter PM10 were collected on quartz filters, and the amounts of organic carbon, elemental carbon, radiocarbon (14C) and levoglucosan were measured. This approach enabled source apportionment of the total c...

Phosphate solublization activity of Bacillus subtilis in different carbon and nitrogen sources with insoluble form of phosphate sources like tricalcium phosphate and rock phosphate were studied. TCP solubilization with different carbon sources irrespective of incubation period can be related in the following order: glucose, fructose, arabinose, mannose, sucrose, lactose, and sorbitol. The pH dr...

since renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. given that iran is benefiting from vast steppes, therate of carbon sequestration in them dese...

the impact of phenolic-contaminated water on microbial community structure was assessed using biolog microarrays techniques. the following biolog plates were used: gen iii plates, new test panel for identification of both gram-negative and gram-positive bacteria, ecoplates microarray for evaluation of functional diversity of microbial communities and phenotype microarrays (pms) for characteriza...

semiconducting carbon nanofibers (cnf) are prepared from three different sources, i.e., acetylene, ethanol, and cotton by the chemical vapor deposition (cvd) process. these fibers are having rich elastic, engineering and conductivity properties. fresh self-compacting concrete (scc) flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, wi...

Textile dyes with different chemical structures are consistently used in textile industries and they are being recalcitrant xenobiotic in nature. The aim of present research is directed to finding the preference of striking carbon and nitrogen sources on remazol golden yellow decolorization. Bacterial strains were isolated, screened and tested for dye degradation of remazol golden yellow in bas...

The growth of meat-spoiling Pseudomonasfragi 72 was studied on a defined salt medium supplemented with L-aspartate, citrate, creatine, creatinine, D-glucose, L-glutamate, and L-lactate. The utilization of the different carbon sources was followed in batch and continuous culture and under the influence of oxygen limitation and carbon dioxide inhibition (50% CO2 in air). Under nonrestricted atmos...

A pot experiment was conducted during Kharif season, 2005 to ascertain the response of different organic sources viz., wheat straw, farm yard manure (FYM), vermicompost and poultry manure to rice (Oryza sativa) and also to monitor the effect of manuring on soil carbon pools. Application of poultry manure and vermicompost alongwith chemical fertilizers for supply of nitrogen, phosphorus and pota...
