Seeds of the plant quince are a natural hydrocolloid source whose extract has shown promising results in stabilizing emulsions. The study aims to discover how quince seed extract's interfacial properties (dynamic surface tension and dilatational surface rheology) on an oil–water interface change with varying concentrations (between 0.01% and 1%), pH's (3, 7, and 11), and ionic strengths (0.1, 0.3, 0.5 M NaCl). The lowest concentration that yielded a statistically significant drop in interfacial was found as 0.02 % w/v. QSE dropped interfacial tension down to 16 mN/m at the highest concentration examined (1% w/v). Critical aggregation concentration (CAC) was identified as 0.23 % w/v, which is relatively low compared to hydrocolloids of similar nature. In the end, QSE was demonstrated to be an effective emulsion stabilizer and possesses some unique properties that help it distinguish itself from other macromolecular emulsifiers commonly employed in the food, chemical, and pharmaceutical industries.

Investigation of sugar metabolism in rhizopus oryzae Büyükkileci, Ali Oğuz; Hamamcı, Haluk; Department of Biotechnology (2007) Rhizopus oryzae is a filamentous fungus, which can produce high amounts of L(+)-lactic acid and produces ethanol as the main by-product. In an effort to understand the pyruvate branch point of this organism, fermentations under different inoculum and glucose concentrations were carried out. At low inoculum size (1x103 spores ml-1), high amount of lactate (78 g l-1) was produced, whereas high ethanol concentration (37 g l-1) was obtained at high inoculum sizes (1x106 spores ml-1). Decreasing working volume i...
Investigation of chemopreventive and apoptotic characteristics of turkish medicinal plant rheum ribes Uyar, Pembegül; Çoruh, Nursen; İşcan, Mesude; Department of Biotechnology (2011) Rheum species are medicinally important plants due to the presence of anthracene derivatives and in this study antioxidative, cytotoxic, apoptotic and chemopreventive characteristics of R. ribes extracts were evaluated. R. ribes shoot and root dry powder samples were prepared and extracted with ethyl acetate, ethanol and water. The extracts were revealed to be a potential scavenger of DPPH radicals and the chemical composition of the extracts was quantified by colorimetric determination of total phenol (GAE...
Investigation the effects of different support medium on product with nutrient film technique İncemehmetoğlu, Ali; Yıldız, Fatih; Özen, Can; Department of Biotechnology (2012) Hydroponics basically is the method of growing plants using mineral nutrient solutions, in water, without soil. Vertical nutrient film technique (NFT) is one of the most used hydroponic technique that has constant flow of nutrient solution. In this study the effects of different support medium on strawberry quality and yield using vertical NFT in glass greenhouse was investigated. NFT-only system was compared to rockwool, coco fiber, perlite and expanded clay as supporting medium for strawberry production. ...
Characterization of emulsion stabilization properties of quince seed extract as a new source of hydrocolloid Kırtıl, Emrah; Öztop, Halil Mecit (2016-07-01) The capability of seed extracts in stabilizing emulsions has particularly received interest in recent years. Upon soaking quince seeds into water, biopolymers inside the seeds are extracted to water, forming mucilage. This study investigates the physical stability, rheology and microstructure of oil (sunflower oil) in water emulsions, stabilized by 2% (w/v) whey protein isolate with varying concentrations of xanthan and quince seed gum. Quince seed gum resulted in emulsions with smaller low-shear viscositie...
Investigation of bioreactor operation conditions for serine alkaline protease production by Bacillus subtilis Özdemir, Elif; Çalık, Pınar; Department of Chemical Engineering (2003) In this study, complex medium was designed for increasing serine alkaline protease (SAP) production by recombinant Bacillus sp. In this context, the effects of glucose, sucrose, inorganic nitrogen source, casein, defatted soybean, and molasses and their concerted effects were investigated in agitation (N=200 min"1) and heating rate (T=37°C) controlled laboratory scale bioreactors. For this purpose, experiments were started by microorganism selection. It was found that, most suitable microorganism for comple...
