Article
Owing to rising population and increasing energy demand, renewable energy resources become the most convenient and promising solution. Hence, solar power plant investments and photovoltaic module numbers have risen sharply. Turkey is one of the tight followers of the energy trends, thanks to its rising energy demand and economic power. However, the...

Nowadays, “energy production” and “global climate change and mitigation”, which are in direct relation with each other, are the most important environmental problems waiting for a solution. Renewable and sustainable energy sources provide the most appropriate alternatives for the solution of this problem. In Turkey, one of the important raw materia...
Article
It is well known that energy-related emissions have been increasing the global warming and pushing the climate change. In the face of this situation biomass-based biofuels, which is a kind of renewable energy source, are great alternatives instead of fossil derivative fuels. Moreover, biomass can be found easily and widely, which makes it an econom...

Bioenergy is a sort of renewable energy source, such as bioenergy, bioethanol, biogas or bioethanol, and it has widespread application in the world. The main purpose of this work is to optimize the physicochemical processes of sulfuric acid and ultrasound + sulfuric acid pretreatment application to get more energy per unit mass from the corncob. In...

The rural settlement area of Niğde Çukurkuyu was chosen as a model location in this study to support rural development and sustainability. In order to identify the feasibility of the technology; the population, energy consumption, available potential raw materials (household and agricultural waste amount depending on years) of the settlement have b...
Article
One of the main triggers of the climate change is the consumption of fossil derivative fuel to satisfy the energy need, and also it is clearly known that the future of the fossil fuel supply is limited. That is why, finding and using alternative, sustainable, renewable, and eco-friendly energy sources are inevitable to fight climate change and to r...
Conference Paper
Bioenergy is a kind of a renewable energy source such as bioethanol, biogas or biobutanol, which have been find widespread applications in the world. The main purpose of the study is to obtain more energy efficiency per unit mass of corncob by applying H2SO4 physico-chemical processes to the corncob in the production of biofuel. Corncob comes from...

Among the economically viable and ecologically acceptable solutions for the safe disposal of waste glycerol coming from biodiesel production, the biotechnological conversion of glycerol into a very high-value-added bioplastic raw material, namely 1,3 propanediol (1,3-PDO) seems to be very promising. This process is easy and environmentally friendly...
Article
Immobilized cultures of locally isolated Klebsiella pneumoniae (GenBank no: 27F HM063413) were employed in the continuous production of the high value added biomonomer, 1,3-propanediol from waste glycerol. The effect of hydraulic retention time (HRT) was tested by increasing the dilution rate gradually. Three different immobilization materials (sta...

In this study, pumice stone (PS), which is a vastly available material in Turkey, was evaluated as an alternative immobilization material in comparison to other commercially available immobilization materials such as glass beads and polyurethane foam. All immobilized bioreactors resulted in much better 1,3-propanediol production from waste glycerol...

The fermentative production of 1,3-propanediol (1,3-PDO) by Klebsiella pneumoniae under different initial substrate concentrations (between 5 and 110g/L) was investigated. It was found that glycerol was almost 100% utilized and 1,3-PDO production increased up to 20g/L of influent substrate concentration, but there was a significant decrease in both...
Article
The feasibility of the continuous production of a valuable bioplastic raw material, namely 1,3-propanediol (1,3-PDO) from biodiesel by-product glycerol, using immobilized cells was investigated. In addition, the effect of hydraulic retention time (HRT) was also analysed. Ceramic balls and ceramic rings were used for the immobilization of a locally...
Article
The continuous production of 1,3-propanediol (1,3-PDO) was investigated with Clostridium beijerinckii NRRL B-593 using raw glycerol without purification obtained from a biodiesel production process. Ceramic rings and pumice stones were used for cell immobilization in a packed-bed bioreactor. For comparison purpose, a control bioreactor with suspend...
Article
Owing to the significant interest in biofuel production in the form of biodiesel, vast amount of glycerol as a waste product is produced all over the world. Among the economically viable and ecologically acceptable solutions for the safe disposal of this waste, biotechnological conversion of glycerol into a valuable bioplastic raw material, namely...
Article
Klebsiella species are excellent 1,3-propanediol (1,3 PDO) producers. Klebsiella pneumoniae is a well-studied microorganism and, therefore, its metabolic pathway is known. Accordingly, a number of by-products are simultaneously produced together with 1,3 PDO. Optimization of medium composition significantly decreased these byproducts' concentration...

Hydrogen production from cheese whey wastewater via dark fermentation was conducted using mixed culture under mesophilic (36�C � 1) and thermophilic (55�C � 1) conditions, respectively. The hydrogen yields and specific hydrogen production rates were found as follows: mesophilic: 9.2 mmol H2 /g COD (chemical oxygen demand) and 5.1 mL H2 /g VSS h; th...
