Co-production of pectinase, xylanase and cellulase complex using Bacillus subtilis grown on food processing wastes



Co-combustion of biocoal and lignite in a circulating fluidised bed combustor to decrease the impact on global warming
Keivani, Babak; OLGUN, HAYATİ; Atımtay, Aysel (2019-01-01)
This work covers co-combustion of biocoal obtained from red pine wood chips with Orhaneli lignite in a 30 kW-thermal capacity circulating fluidised bed combustor (CFBC) system in air and oxygen-enriched atmosphere. The combustor was of 108 mm inside diameter and 6 m height. The combustion temperature was held at 850+50 degrees C. Oxygen enriched combustion tests were carried out at different ratios of lignite and biocoal mixtures. Biocoal share in the fuel mixture was increased up to 50% by wt. It was found...
Co-delivery of Doxorubicin and D-alpha-Tocopherol Polyethylene Glycol 1000 Succinate by Magnetic Nanoparticles
Metin, Esra; Mutlu, Pelin; Gündüz, Ufuk (2018-01-01)
Background: Although conventional chemotherapy is the most common method for cancer treatment, it has several side effects such as neuropathy, alopecia and cardiotoxicity. Since the drugs are given to body systemically, normal cells are also affected, just like cancer cells. However, in recent years, targeted drug delivery has been developed to overcome these drawbacks.
Co-combustion of high and low ash lignites with raw and torrefied biomass under air and oxy-fuel combustion atmospheres
Barzegar, Ramin; Yozgatlıgil, Ahmet; Atımtay, Aysel (2022-02-01)
Co-combustion characteristics of high and low ash lignites blended with raw and torrefied pine woodchips were studied by Thermogravimetric Analyzer (TGA) under air and oxy-fuel conditions. The lignites were blended with biomass samples at the mass fraction of 50/50 wt.%. Three heating rates of 10, 20, and 40 degrees C/min were chosen, and the characteristic temperatures, including initial, ignition, and burnout temperatures, were obtained. In order to estimate the activation energies of the co-combustion of...
Co-production of xylanase and itaconic acid by aspergillus terreus nrrl 1960 on agricultural biomass and biochemical characterization of xylanase
Kocabaş, Aytaç; Bakır, Ufuk; Department of Biotechnology (2010)
Production of xylanase and itaconic acid (IA) from Aspergillus terreus NRRL 1960 from agricultural residues was investigated in this study. Two different media were tested and the medium having itaconic acid inducing capacity was chosen for further studies due to its high xylanase and IA production capacity. The best xylan concentration was found as 2% (w/v). Addition of commercial xylanase to production culture resulted in higher initial simple sugar concentration which increased IA production slightly but...
Co-combustion of sewage sludge from different treatment processes and a lignite coal in a laboratory scale combustor
Sever Akdağ, Ayşe; Atak, Onur; Atımtay, Aysel; Sanin, Faika Dilek (2018-09-01)
One sustainable use of sewage sludge (SS) is to use it as fuel in existing coal-fired plants. Towards this end, this study evaluated thermal characteristics and co-combustion efficiency of dried SS samples from six wastewater treatment plants with different sludge treatment units. Fuel quality of SS based on proximate and ultimate analyses and calorific value, and ash composition by XRF analysis were investigated. Then the SS samples were co-combusted in a laboratory batch reactor in mixtures with coal (3%,...
