Characterization and immobilization of protease and lipase on chitin-starch material as a novel matrix

Wesen Adel Mehdi; Atheer Awad Mehde; Özacar, Mahmut; Zeynep Ozacar (ELSEVIER SCIENCE BV, 2018)

Protease and lipase were purified from sunflower seeds by frequent purification steps with molecular weights of 72.90 kDa and 27.50 kDa, respectively. The purified lipase and protease were immobilized on various carriers ...
Evaluation of different saccharides and chitin as eco-friendly additive to improve the magnetic cross-linked enzyme aggregates (CLEAs) activities

Atheer Awad Mehde; Wesen Adel Mehdi; Özacar, Mahmut; Zeynep Ziyade Ozacar (ELSEVIER SCIENCE BV, 2018)

The cross-linked enzyme aggregates (CLEAs) involves formation of a number of covalent bonds between enzyme and the matrix using glutaraldehyde. In general, amino groups of lysine, sulthydryl groups of cysteine, phenolic ...
Genetic polymorphisms of human transcription factor-7 like 2 (TCF7L2), beta-defensin (DEFB1) and CD14 genes in nephrolithiasis patients

Wesen Adel Mehdi; Atheer Awad Mehde; Raha Ahmed Raus; Faridah Yusof; Zaima Azira Zainal Abidin; Hamid Ghazali; Azlina Abd Rahman; Özacar, Mahmut (ELSEVIER SCIENCE BV, 2018)

Conclusions: The present findings are first of its class that validates a considerable connection of DEFB1 and TCF7L2 gene polymorphisms with nephrolithiasis and could probably act as indicators to estimate the risk ...
Lipase-based on starch material as a development matrix with magnetite cross-linked enzyme aggregates and its application

Atheer Awad Mehde; Wesen Adel Mehdi; Severgün, Olcay; Soner Cakar; Özacar, Mahmut (ELSEVIER SCIENCE BV, 2018)

The Fe3O4 magnetic nanoparticles were prepared by precipitating ferrous ion (Fe2+) and ferric ion (Fe3+) in alkaline solution. The Fe3O4 magnetic nanoparticles were modified by tannic acid. After functionalization process, ...
The novel multi cross-linked enzyme aggregates of protease, lipase, and catalase production from the sunflower seeds, characterization and application

Özacar, Mahmut; Atheer Awad Mehde; Wesen Adel Mehdi; Zeynep Ziyade Ozacar; Severgün, Olcay (ELSEVIER SCIENCE BV, 2019)

The cross-linked enzyme aggregates (CLEAs) have numerous economic advantages in the industrial bio catalysis. In the present study, the multi CLEAs containing protease, catalase, and lipase from the sunflower seeds using ...
