Plant secondary metabolites constitute a useful array of natural ingredients, especially for therapeutics, the food additives industry, and many other industrial fields. Thereby, metabolic engineers are looking for alternative strategies that may be more efficient for the enhancement of valuable secondary metabolite production quality and quantity. However, the knowledge of production pathways and related enzymes of secondary metabolites is quite scarce. In this study, we aim to build a biochemical reaction networkstoring paths between source and target molecules where intermediates are known metabolites of a given organism (plant and/or Escherichia coli), besides related reactions, enzymes, and genes data. The tool that is predominantly used in this study to reveal the unknowns of production pathways is RetroPath2.0 workflow on KNIME analytics platform. It is a rule-based retrosynthesis tool that can suggest possible production pathways for a given molecule along with precursor and intermediate molecules and enzymes by processing reaction rules and available compounds in the environment. The output of RetroPath2.0 contains possible pathways ranked according to feasibility. The RetroPath2.0 tool is being executed for 16 valuable secondary metabolites to discover their possible production pathways in a common plant metabolites pool (based on metabolic models of Arabidopsis thaliana, Oryza sativa and Zea mays) and E. coli metabolites pool. The resulting pathway suggestions are integrated into the metabolic database. This procedure serves as a promising method to uncover the unknowns of plant metabolome and propose new feasible production pathways of valuable plant secondary metabolites. Thus, it has the potential to make industrial production of these economically important plant secondary metabolites more efficient in terms of production quality and quantity. This study is supported by Yildiz Technical University Scientific Research Projects Coordination Unit with the project number FBA-2021-4698.

Investigation of the role of a candidate effector of wheat stripe rust pathogen in plant immunity Dagvadorj, Bayantes; Akkaya, Mahinur S.; Hakkı, Erdoğan Eşref; Department of Biotechnology (2016) The advanced plant molecular biology and plant biotechnology tools were employed in this thesis, in order to understand the role of a candidate effector, PstSCR1, of Puccinia striiformis f. sp. tritici (Pst) causing yellow rust disease in wheat. The homologues proteins of PstSCR1 were found to be only conserved in Pst, and in its closest relative, Puccinia graminis f. sp. tritici (Pgt). When PstSCR1 was expressed in Nicotiana benthamiana with its signal peptide (SP), it provoked the plant defense, whereas n...
An investigation of the relationship between compressive strength and dust generation potential of magnetite pellets SİVRİKAYA, OSMAN; Arol, Ali İhsan (Elsevier BV, 2013-09-10) Iron ore pellets should have sufficient mechanical strengths against degradation at all stages of pellet production in pelletizing plants. Besides the strength, pellets should have less dust emission during operation since the process efficiency and the pelletizing equipments are adversely affected by dust. Dust is also a problem for sintered (product) pellets since they abrade during transportation from pellet production site to the reduction facilities. Sufficient mechanical strength and low dust emission...
The effect of solids concentration and particle properties on cloud height in tall stirred tanks Altıntaş, Ezgi; Ayrancı Tansık, İnci; Department of Chemical Engineering (2021-6) Solid-liquid mixing is one of the most commonly used unit operations in industries such as petrochemicals, polymer processing, biotechnology, pharmaceuticals, and mineral processing. There are two focuses in solid-liquid mixing operations: solids suspension and solids distribution. The key design parameter for solids suspension is Njs. In most solids suspensions, the main objective is to provide maximum contact between solid and liquid phases with minimum power consumption, and this can be achieved by setti...
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 surface properties of quince seed extract as a novel polymeric surfactant Kirtil, Emrah; Svitova, Tatyana; Radke, Clayton J.; Öztop, Halil Mecit; Şahin, Serpil (2022-02-01) © 2021 Elsevier LtdIn recent years, there is a growing trend from both academia and the industry towards the use of “clean-labeled” ingredients obtained from renewable resources. Proteins and polysaccharides, in particular, are becoming increasingly popular as alternatives to already well-established synthetic surfactants. Quince seeds are a relatively novel hydrocolloid source that has recently raised interest among researchers due to their strong surface activity and viscosity-enhancing properties. This s...
