Acid production in wines inoculated with acetic acid bacteria from vinegar was studied at 15-degrees-C, 20-degrees-C, 25-degrees-C and 30-degrees-C and simulated with kinetic models. Results indicated that major wine spoilage did not occur during the growth of the microorganisms, but during their extended presence at high concentrations during the stationary and death phases. Acetophilic species were observed to resist death, which is in agreement with the mechanism suggested by Kittelmann et al.9 for the development of gradual acid tolerance by acetic acid bacteria.

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...
Effects of High Hydrostatic Pressure (HHP) Processing and Temperature on Physicochemical Characterization of Insect Oils Extracted from Acheta domesticus (House Cricket) and Tenebrio molitor (Yellow Mealworm) Ugur, Ahmet Erdem; Bolat, Berkay; Öztop, Halil Mecit; Alpas, Hami (Springer Science and Business Media LLC, 2020-11-01) Oil portion of Tenebrio molitor (yellow mealworm) and Acheta domesticus (house cricket) were examined and it was investigated how the physicochemical properties of the oils changed with High Hydrostatic Pressure Assisted Extraction (HHP-E) and conventional solvent extraction (CE) with hexane. The effect of HHP-E at 500 MPa and 30 and 40 degrees C for 15 min on the properties of oils was compared with the CE. Following the extraction of oil, fatty acid composition, peroxide value, crystallization and melting...
Oxygen transfer effects in beta-lactamase fermentation by Bacillus licheniformis in a glucose-based defined medium Çalık, Pınar; Calik, G (Wiley, 2005-09-01) The effects of oxygen transfer on the beta-lactamase production by Bacillus licheniformis were investigated in a glucose-based defined medium. The experiments were conducted in 3.0 dm(3) batch bioreactor systems at three different air inlet (Q(O)/V-R = 0.2, 0.5 and 1.0 vvm) and agitation rates (N = 250, 500 and 750 min(-1)). During the fermentation, the concentrations of the cell, glucose, by-products, ie organic and amino acids, oxygen transfer coefficients (K(L)alpha), yield coefficients, specific rates a...
Effect of pH, flow rate and concentration on the sorption of Pb and Cd on montmorillonite: I. Experimental Altin, O; Ozbelge, OH; Doğu, Timur (Wiley, 1999-12-01) Continuous column adsorption of lead (Pb) and cadmium (Cd) was studied using pH adjustment and calcium-saturated montmorillonite in a short stainless steel column. Changing either pH or flow rate, while keeping inlet concentration of the ions constant, led to considerable changes in effluent concentrations and breakthrough curves (BTCs). At low pH values (2-4), H+ ions competed strongly with lead and cadmium ions; at intermediate pH (4-6), ionic size played the major role in adsorption and ion exchange and ...
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).
