The bio-hydrogen generation potential of sugar industry wastes was investigated. In the first part of the study, acidogenic anaerobic culture was enriched from the mixed anaerobic culture (MAC) through acidification of glucose. In the second part of the study, glucose acclimated acidogenic seed was used, along with the indigenous microorganisms. MAC, 2-bromoethanesulfonate treated MAC and heat treated MAC. Two different COD levels (4.5 and 30 g/L COD) were investigated for each culture type. Reactors with initial COD concentration of 4.5 g/L had higher H-2 yields (20.3-87.7 mL H-2/g COD) than the reactors with initial COD concentration of 30 g/L (0.9-16.6 mL H-2/g COD). The 2-bromoethanesulfonate and heat treatment of MAC inhibited the methanogenic activity, but did not increase the H-2 production yield. The maximum H-2 production (87.7 mL H-2/g COD) and minimum methanogenic activity were observed in the unseeded reactor with 4.5 g/L of initial COD.

Kinetic modeling of enzymatic hydrolysis of pretreated kitchen wastes for enhancing bioethanol production Çekmecelioğlu, Deniz (Elsevier BV, 2013-03-01) It is well known that use of low cost and abundant waste materials in microbial fermentations can reduce product costs. Kitchen wastes disposed of in large amounts from cafeterias, restaurants, dining halls, food processing plants, and household kitchens contain high amounts of carbohydrate components such as glucose, starch, and cellulose. Efficient utilization of these sugars is another opportunity to reduce ethanol costs. In this study, the effect of pretreatment methods (hot water, acid solutions, and a...
A techno-sustainable bio-waste management strategy for closing chickpea yield gap Ozdemir, Saim; Özdemir, Serkan; Ozer, Hasan; YETİLMEZSOY, Kaan (Elsevier BV, 2021-01-01) © 2020 Elsevier LtdSustainable development goals imply environmentally sound management of all wastes to minimize the waste generation through prevention, reduction, recycling, and reuse. In particular, the poultry industry produces nutrient-rich waste that requires proper management. Additionally, the recycling of bio-wastes in agricultural lands is still a key technology for the sustainable use of nutrients as a renewable fertilizer. Currently, there are very few studies on the utilization of agro-industr...
Demonstration and optimization of sequential microaerobic dark- and photo-fermentation biohydrogen production by immobilized Rhodobacter capsulatus JP91 Sağır, Emrah; Yucel, Meral; Hallenbeck, Patrick C. (Elsevier BV, 2018-02-01) Hydrogen generation from complex substrates composed of simple sugars has the potential to mitigate future worldwide energy demand. The biohydrogen potential of a sequential microaerobic dark- and photo-fermentative system was investigated using immobilized Rhodobacter capsulatus JP91. Biological hydrogen production from glucose was carried out using a batch process and a bench-scale bioreactor. Response surface methodology with a Box-Behnken design was employed to optimize key parameters such as inoculum c...
Investigation of adsorption of pesticides by organo-zeolite from wastewater Lüle, Güzide Meltem; Atalay, M Ümit; Özbayoğlu, Gülhan; Department of Mining Engineering (2011) The aim of this study was to determine the adsorption capacity of activated carbon and organo-zeolites for removal of pesticides in water. In order to prepare organo-zeolite, two kinds of cationic surfactants, namely, hexadecyltrimethyl ammonium bromide (HTAB) and dodecyltrimethyl ammonium bromide (DTAB) were used. Adsorption studies of cationic surfactant on zeolite were investigated in respect to initial concentration of cationic surfactant, time, and temperature. It has been found that the best fitted is...
Application of spatial and non-spatial data analysis in determination of the factors that impact municipal solid waste generation rates in Turkey KESER, Saniye; Duzgun, Sebnem; Aksoy, Ayşegül (2012-03-01) In studies focusing on the factors that impact solid waste generation habits and rates, the potential spatial dependency in solid waste generation data is not considered in relating the waste generation rates to its determinants. In this study, spatial dependency is taken into account in determination of the significant socio-economic and climatic factors that may be of importance for the municipal solid waste (MSW) generation rates in different provinces of Turkey. Simultaneous spatial autoregression (SAR)...
