This paper focuses on a new granulation study area where a mixture of suspended anaerobic and aerobic cultures was used as seed. Mixed suspended anaerobic and aerobic cultures exposed to alternating anaerobic/microaerobic/aerobic conditions developed granulates up to 2.5 mm in size. The granules developed displayed both oxygen uptake (3.83 - 8.75 mg dissolved oxygen g(-1) volatile suspended solids h(-1)) and methanogenic activities (7.5 cm(3) CH4 d(-1)) comparable to those of aerobic and anaerobic control cultures, respectively. Oxygen doses of 60, 100 and 120% of the total chemical oxygen demand added (23, 38 and 45 cm 3) and ethanol (among ethanol, glucose, acetic acid, and glucose+acetic acid) resulted in the largest and the most stable granules.

Metabolic reaction network of Pichia pastoris with glycosylation reactions: Flux analysis for erythropoietin production
Eskitoros, Melda S.; Ata, Ozge; Çalık, Pınar (Wiley, 2014-11-01)
BACKGROUND: Biochemical reaction network of Pichia pastoris was improved by including N-glycosylation pathway reactions to determine the intracellular reaction rates for glycosylated protein production.
EFFECTS OF SUBSTRATE CONCENTRATION ON GROWTH AND LACTIC-ACID PRODUCTION BY MIXED CULTURES OF LACTOBACILLUS-BULGARICUS AND STREPTOCOCCUS-THERMOPHILUS
OZEN, S; OZILGEN, M (Wiley, 1992-01-01)
The kinetics of growth and lactic acid production by mixed cultures of Lactobacillus bulgaricus and Streptococcus thermophilus were modeled with a set of modified logistic and Luedeking-Piret equations. The specific growth rates and the inhibitory effect of each individual species on the mixed culture growth were found to be determined by the media composition. The kinetic analysis clearly showed that the contribution of each microbial species to the mixed culture growth process changed drastically when the...
Fermentation and oxygen transfer characteristics in recombinant human growth hormone production by Pichia pastoris in sorbitol batch and methanol fed-batch operation
Çalık, Pınar; Soyaslan, Elif S.; Sahin, Merve; Taspinar, Hatice; Acik, Eda; Bayraktar, Eda (Wiley, 2010-02-01)
BACKGROUND: The influence of methanol feed rate on recombinant human growth hormone (rhGH) production by Pichia pastoris hGH-Mut(+) in medium containing sorbitol was investigated at three different specific growth rates (mu), namely, 0.02 (MS-0.02), 0.03 (MS-0.03), and 0.04 (MS-0.04).
Fermentation and oxygen transfer characteristics in serine alkaline protease production by recombinant Bacillus subtilis in molasses-based complex medium
Calik, G; Pehlivan, N; Ozcelik, IS; Çalık, Pınar; Ozdamar, TH (Wiley, 2004-11-01)
Serine alkaline protease (SAP) production in a complex medium based on physically pretreated molasses by recombinant Bacillus subtilis carrying pHV1431::subC gene is described. The effects of oxygen transfer were investigated in 3.5 dm(3) bioreactor systems with controls for agitation rate, dissolved oxygen, pH, temperature, and foam formation under two different agitation rates, ie N = 500 and 750 min(-1), and four different air flow rates, ie Q/V-R = 0.2, 0.5, 0.7, and 1.0 vvm, at a molasses concentration...
Biochemical methane potential (BMP) of solid organic substrates: evaluation of anaerobic biodegradability using data from an international interlaboratory study
Raposo, F.; et. al. (Wiley, 2011-08-01)
BACKGROUND: This paper describes results obtained for different participating research groups in an interlaboratory study related to biochemical methane potential (BMP). In this research work, all experimental conditions influencing the test such as inoculum, substrate characteristics and experimental conditions were investigated. The study was performed using four substrates: three positive control substrates (starch, cellulose and gelatine), and one raw biomass material (mung bean) at two different inocul...
