A cold adapted lipolytic bacterium Curtobacterium sp. was isolated from the soil of Gangotri glaciers, Western Himalayas. The optimum temperature and pH for cold active lipase activity was 15 C and 8.0 respectively. The effect of different carbon sources, organic and inorganic nitrogen sources on production of cold active lipase were studied. Glucose served as a good source of carbon for the pr...

Oxidation of soils with 333 mM potassium permanganate (KMnO4) has been identified as a means to quantify labile soil carbon (C) and may have potential for rapid measurement of biologically active soil C. In the current study, active C pools in several soils were estimated by oxidation with a range of KMnO4 concentrations and compared to estimates determined from carbon dioxide evolution during ...

Introduction: Active packaging is one of the innovations in food packaging industry that would be a respons to the changing needs of consumers and markets. In this technique, materials such as adsorbents oxygen, moisture, carbon dioxide, ethylene and carbon dioxide-releasing flavor compounds, antimicrobials, antioxidants and various aromatic compounds are used. In the last deca...

Carbon nanotubes are of great interest due to their high surface area and rich edge sites, which are favorable for wide applications. Here, a simple and efficient routine is presented by decoration of multi-wall carbon nanotube (MWCNT) with nickel oxide (NiO) nanoparticles.The morphologies of NiO-MWCNT  were  investigated  by  using scanning  electron  microscope  (SEM)  and energydispersive X-...

The potential of carbon nanotubes (CNT) supported cobalt catalysts for Fischer-Tropsch (FT) reaction is shown. Using the wet impregnation method cobalt on carbon nanotubes catalysts were prepared with cobalt loading varying from 15 to 45 wt. %. The catalysts are characterized by different methods including: BET physisorption, X-ray diffraction, hydrogen chemisorption, and temperature-progra...

We present measurements of the emission from the centers of fifteen spiral galaxies in the P1 − 3 P0 [CI] fine-structure transition at 492 GHz. Observed galaxy centers range from quiescent to starburst to active. The intensities of neutral carbon, the J=2–1 transition of CO and the J=4–3 transition of CO are compared in matched beams. Most galaxy centers emit more strongly in [CI] than in CO, c...

introduction: soil organic matter is influenced strongly by vegetation cover and management, therefore it is proposed as the main indicator of soil quality and health. the changes in soil organic matter status occur much more rapidly in the labile pools than in organic c. thus, labile pools can be used as early indicators of changes in total organic matter that will become more obvious in the l...

BACKGROUND Marine angiosperms, seagrasses, are sentinel species of marine ecosystem health and function. Seagrass carbon budgets provide insight on the minimum requirements needed to maintain this valuable resource. Carbon budgets are a balance between C fixation, growth, storage and loss rates, most of which are well characterized. However, relatively few measurements of dissolved organic carb...
