Feedstock Recycling of PLA in the Presence of Mesoporous Catalysts



Feedstock optimization of in-vessel food waste composting systems for inactivation of pathogenic microorganisms
Çekmecelioğlu, Deniz; Graves, RE (International Association for Food Protection, 2005-03-01)
An optimum composting recipe was investigated to reduce pathogenic microorganisms in a forced-aerated in-vessel system (55 liters). The feedstocks used for in-vessel composting were food waste, cow manure, and bulking materials (wood shavings and mulch hay). A statistical extreme vertices mixture design method was used to design the composting experiments and analyze the collected data. Each mixture (nine total) was replicated randomly three times. Temperature was monitored as an indicator of the efficiency...
Trace elements partitioning during co-firing biomass with lignite in a pilot-scale fluidized bed combustor
Gogebakan, Zuhal; Selçuk, Nevin (2009-03-15)
This study describes the partitioning of 18 trace elements (As, Ba, Cd, Co, Cr, Cu, Li, Mn, Mo, Ni, P, Pb, Sb, Se, Sn, Tl, V, Zn) and 9 major and minor elements (Al, Ca, Fe, K, Mg, Na, S, Si, Ti) during co-firing of olive residue, hazelnut shell and cotton residue with high sulfur and ash content lignite in 0.3 MWt Middle East Technical University (METU) Atmospheric Bubbling Fluidized Bed Combustor (ABFBC) test rig with limestone addition. Concentrations of trace elements in coal, biomass, limestone, bottom...

Biohydrogen production in an outdoor panel photobioreactor on dark fermentation effluent of molasses
Avcioglu, Sevler Gokce; Ozgur, Ebru; Eroglu, Inci; Yucel, Meral; Gündüz, Ufuk (2011-08-01)
Hydrogen is regarded as an ideal energy carrier if it is produced from renewable resources such as biomass. Sequential operation of dark and photofermentation allows a highly efficient production of hydrogen from biomass, as maximal conversion of the energy in the carbohydrates to hydrogen can be achieved. In this study photofermentative hydrogen production was carried out in a solar panel photobioreactor by Rhodobacter capsulatus wild type (DSM 1710) and Rhodobacter capsulatus hup(-) (YO3) strain on the mo...
Bioprocess parameters and oxygen transfer characteristics in beta-lactamase production by Bacillus species
Celik, E; Çalık, Pınar (Wiley, 2004-03-01)
After screening potential beta-lactamase producers in a medium containing penicillin G, an inducible (Bacillus subtilis NRS 1125) and a constitutive (Bacillus licheniformis 749/C ATCC 25972) P-lactamase producer were selected. As the highest enzyme activity was obtained with B. licheniformis 749/C, the effects of the concentration of carbon sources, i.e., glucose, fructose, sucrose, citric acid, and glycerol, and nitrogen sources, i.e., (NH4)(2)HPO4, NH4Cl, yeast extract, casamino acids and peptone, pH, and...
