Conference Object Citation - WoS: 1Kinetic and Thermodynamic Properties of Crude and Three-Phase Partitioned Polygalacturonase From Aspergillus Sojae(Elsevier, 2007) Doğan, Nergiz; Tari, Canan; Göğüş, NihanCommercial preparations of pectinolytic enzymes derived from fungi are well known to have high biotechnological value in the industry. Since potential applications of pectinases in vari- ous fields of food, paper, textile and waste water treatment are increasing, it is important to understand the properties of these enzymes for efficient and effective usage.Conference Object Citation - WoS: 1Optimization of Exo-Polygalacturonase Production From Orange Peel by Aspergillus Sojae(Elsevier, 2010) Büyükkileci, Ali Oğuz; Tarı, Canan; Fernandez-Lahore, H. M.; Gençkal Demir, Hande; Göğüş, NihanPectinases catalyze the degradation of pectic substances, thus they are used extensively in fruit juice and wine industry to facil-itate extraction and clarification. Aspergillus species, in particular Aspergillus niger, have long been utilized for production of pectinases. Previous studies of our group showed that A. sojae has a potential to produce enhanced amount of polygalacturonase, which is one of the pectic enzymes, in both submerged and solid-state cultures (Gogus et al., 2006; Tari et al., 2007). In this study, several agricultural products were screened in an effort to find a cheap and abundant substrate for submerged polygalacturonase production using a UV-mutated A. sojae strain. Medium composition was optimized to further enhance the enzyme level. Experiments were designed and analyzed statistically using the trial version of the statistical software, Design Expert.
