Carbon sources affect metabolic capacities of Bacillus species for the production of industrial enzymes: theoretical analyses for serine and neutral proteases and alpha-amylase
Çalık, Pınar (Elsevier BV, 2001-07-01)
The metabolic fluxes through the central carbon pathways were calculated for the genus Bacillus separately for the enzymes serine alkaline protease (SAP), neutral protease (NP) and alpha -amylase (AMY) on five carbon sources that have different reduction degrees (gamma), to determine the theoretical ultimate limits of the production capacities of Bacillus species and to predict the selective substrate for the media design. Glucose (gamma = 4.0), acetate (gamma = 4.0), and the TCA cycle organic-acids succina...
Nitrogen cycling in the offshore waters of the Black Sea
McCarthy, James J.; Yılmaz, Aysun; Coban-Yildiz, Yesim; Nevins, John L. (2007-09-01)
The purpose of this study was to measure directly the rates of several of the processes responsible for the production and utilization of nitrogenous nutrients, and to use these rates and other data to generate an annual nitrogen budget for the Black Sea. Water column samples and experimentation with (15)N labeled nutrients in the offshore waters of the Black Sea reveal strong seasonal cycles in the utilization of different forms of N, the regeneration of NH(4)(+) and the production of NO(2)(-) in and below...
Organic nitrogen in rain and aerosol in the eastern Mediterranean atmosphere: An association with atmospheric dust
Mace, KA; Kubilay, N; Duce, RA (2003-05-31)
From March through early May of 2000, rain and bulk aerosol samples were collected at a coastal site on the eastern Mediterranean Sea at Erdemli, Turkey, and analyzed for nitrogen (N) species, including nitrate (NO3-), nitrite (NO2-), ammonium (NH4+), water-soluble organic N, urea, and dissolved free amino acids. Other ions were also analyzed, including Ca2+, Mg2+, K+, Na+, Cl-, and SO42-. Water-soluble organic N was found to contribute similar to17% and similar to26% of the total water-soluble N in rain an...
Carbon Coating of magnesium via thermal plasma
Aktekin, Burak; Eyövge, Cavit; Öztürk, Tayfur (null; 2018-05-07)
Magnesium is a material of considerable interest for electrochemical as well as thermal energy storage. Carbon coated magnesium or magnesium nanopartciles emebedded in a graphitic matrix could provide solutions to some of the problems currently faced in these application areas. The current study was undertaken to develop Mg-C composites at a variety of length scales. The synthesis was achieved by co-feeding magnesium and methane into an RF thermal plasma reactor. This yielded carbonaceous material with magn...
Carbon coating of magnesium particles
Aktekin, Burak; Eyovge, Cavit; Öztürk, Tayfur (2017-10-05)
Magnesium when hydrided has low thermal and electrical conductivity and carbon coating would be useful to remedy this for a variety of purposes. In this study, carbon coating was achieved by co-feeding magnesium and methane into a thermal plasma reactor. This yielded carbonaceous material with magnesium particles 5-10 nm in size embedded in graphitic matrix. A further reduction down to 2-3 nm was possible but required reductions in the precursor feed rate. 2 wt% carbon was sufficient to fully protect magnes...
