Plastic now pollutes every corner of earth and it is one of the major environmental problems of nowadays. Beside of being directly harmful as a mimic of food sources of marine organisms, as being suitable substrate for different kind of microbes they have also indirect damage. Metataxonomics analysis using Next Generation Sequencing (NGS) technology have revealed numerous previously unrecognized microorganisms. In the present study, micro-plastic attached bacterial community of samples taken from four different depths (0, 25, 150, 200 m) from a North-eastern Mediterranean offshore station (200 m) were investigated using metataxonomics amplicon sequencing technique. Targeted marine samples were micro-plastic attached microorganisms, but because of the limited evidence it has been called as Micro-plastic and other particle attached habitats. Those samples also compared with free-living organisms in the area. About 664 Operational Taxonomic Units (OTUs-sequence variants) from 65,457 sequences were observed for all the depths. Caulobacteraceae was the most dominant order in the micro-plastic particle attached marine environment, which the members of taxa are usually known to be biofilm colonizer whereas, SAR 11 clade found to be abundant in the free-living community. Another common bacterium for marine environment was Phenylobacterium that degrades the Chloridazon herbicide and Acinetobacter junii which was shown to have the ability todegrade biodegradable plastic. This is a first study using a culture-independent approach for identify the North-eastern Mediterranean free-living and micro-plastic particle-attached marine microorganisms.

Computer modeling of blowback oil consumption in internal engines
Bilge, Egemen; Dursunkaya, Zafer; Department of Mechanical Engineering (2009)
Environmental pollution is an important problem of our world. Governments are aware of this problem and emission regulations are continuously improved. One of the strictest regulations is about unburned and burned hydrocarbon emissions. In internal combustion engines the origin of the burned and unburned hydrocarbons is fuel and engine oil. As a result of the sanctions and the necessity of improved combustion performance of the engine, manufacturers work on manufacturing technology and engine tribology. Wit...
Bacterial polyhydroxyalkanoates: Biosynthesis, screening and characterisation
Gursel, I; Alaeddinoglu, NG (1997-09-17)
Plastic products are a part of our everyday life, but there are rising concerns worldwide that petroleum-based plastics are having detrimental effects on the environment. These products have estimated degradation times ranging from 20 years for vending machine cups, to 100 years for PET plastic bottles and 500 years for polystyrene foam caps and dishes. Although recycling is improving, about 75% will still be disposed into landfills and new strategies that can overcome this environmental problem will need t...
Sustainability assessment of a hydropower project: a case study of Kayraktepe dam and Hepp
Öztürk, Ayça; Tiğrek, Şahnaz; Department of Civil Engineering (2011)
Nowadays, the world faces with lack of electricity access, water scarcity, climate change and global warming. The hydropower industry has a crucial role to deal with these problems as well as to develop projects for sustainable development. However, if social, environmental and economical impacts of a hydroelectric power plant (HEPP) project are not considered, it might lead to irreparable destructions. Nowadays, in Turkey, due to social and environmental problems resulting from hydropower projects, the opp...
Reactivity of limestones of different sources for flue gas desulfurization application
Gülsün, Mehtap; Hoşten, Çetin; Department of Mining Engineering (2003)
In today's world where millions of tons of pollutants are discharged into the atmosphere, continually increasing population and industrialization lead to ever increasing demand for energy which, in turn, leads to a continual increase in the amount of pollutants released into the atmosphere. Sulphur dioxide generated as a result of burning coal is one of the most significant pollutants in the atmosphere and has negative effects on both living beings and non-living things. There are wet and dry processes whic...
Investigation of alkaline pretreatment parameters on amulti-product basis for the co-production of glucose and hemicellulose based films from corn cobs
Toraman, Hilal Ezgi; Bakır Bölükbaşı, Ufuk; Özkan, Necati; Department of Chemical Engineering (2012)
There is an increasing trend in the world for using renewable sources of fuels and chemicals due to the continuous depletion of fossil fuel reserves besides the environmental issues related with the exploitation of these resources. Lignocellulosic biomass is seen as the most promising candidate to be used instead of fossil sources because of its availability, relatively low price and less competition with food and feed crops. In this study, corn cobs, a lignocellulosic agricultural waste, were subjected to ...
