Ideal Feedstock and Fermentation Process Improvements for the Production of Lignocellulolytic Enzymes
Iram, Attia; Çekmecelioğlu, Deniz; Demirci, Ali (2021-01-01)
The usage of lignocellulosic biomass in energy production for biofuels and other value-added products can extensively decrease the carbon footprint of current and future energy sectors. However, the infrastructure in the p...
Bacterial cellulase production using grape pomace hydrolysate by shake-flask submerged fermentation
Kurt, Ayse Sultan; Çekmecelioğlu, Deniz (2021-01-01)
© 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.Grape pomace is a lignocellulosic waste of wine industry, which comprises high moisture content, cellulose, and hemice...
Distillers' dried grains with solubles (DDGS) and its potential as fermentation feedstock
Iram, Attia; Çekmecelioğlu, Deniz; Demirci, Ali (Springer Science and Business Media LLC, 2020-07-01)
Distillers' dried grain with solubles (DDGS) is a byproduct of bioethanol fermentation, which uses the dry milling technology for starch-rich grains such as corn, wheat, and barley. The current interest in bioethanol is in...
Production of Cellulase and Xylanase Enzymes Using Distillers Dried Grains with Solubles (DDGS) by Trichoderma reeseiat Shake-Flask Scale and the Validation in the Benchtop Scale Bioreactor
Çekmecelioğlu, Deniz; Demirci, Ali (Springer Science and Business Media LLC, 2020-01-01)
Most of the corn-ethanol plants use dry-mill process and generate large volume of distillers dried grains with solubles (DDGS) as the co-product. The DDGS is a promising feedstock with rich content of cellulose and xylan. ...

Kurt, Ayşe Sultan; Çekmecelioğlu, Deniz (2019-11-09)
Comparative study of microbial oil production using Lipomyces starkeyi and Rhodosporidium toruloides yeasts
Gürel, Nermin; Çekmecelioğlu, Deniz (2019-11-07)
Fed batch production of polygalacturonase and pectin lyase enzymes using apple pomace as feedstock
Çekmecelioğlu, Deniz; Güneruz, Ayşe (2019-11-07)
A Statistical Optimization Study on Dilute Sulfuric Acid Pretreatment of Distillers Dried Grains with Solubles (DDGS) As a Potential Feedstock for Fermentation Applications
Çekmecelioğlu, Deniz; Demirci, Ali (2019-11-01)
Distillers dried grains with solubles (DDGS) are co-product of dry-grind ethanol plant, which can be used as a feedstock for fermentation, e.g. for biofuels or other value-added products. However, DDGS loading is a critica...
Optimization of dilute sulfuric acid, aqueous ammonia, and steam explosion as the pretreatments steps for distillers' dried grains with solubles as a potential fermentation feedstock
Iram, Attia; Çekmecelioğlu, Deniz; Demirci, Ali (Elsevier BV, 2019-06-01)
Distillers' dried grains with solubles (DDGS) is the by-product of bioethanol production from starch-rich grains through dry-mill fermentation. In this study, dilute sulfuric acid hydrolysis, aqueous ammonia, and steam exp...
Improvement of Pectinase Production by Co-culture of Bacillus spp. Using Apple Pomace as a Carbon Source
Kuvvet, Ceren; UZUNER, SİBEL; Çekmecelioğlu, Deniz (2019-05-01)
Increasing interest in using food and agricultural wastes for low cost enzyme production continues in fermentation industry. Bacteria, especially Bacillus subtilis, are known to produce pectinases in synthetic media and me...
