A polyphenol oxidase (PPO) from Cimin grape was purified 11.2-fold by using a Sepharose 4B-L-tyrosine-p-aminobenzoic acid affinity column. the optimum pH and temperature of PPO purified from Cimin grape were 7.5 and 30 ...

Purification and characterization of an extracellular lipase from Mucor hiemalis f. corticola isolated from soil

Ülker, Serdar; Karaoğlu, Şengül Alpay (Elsevier, 2012)

We have screened 39 microfungi isolates originated from soil in terms of lipolytic activity. Out of all screened, a novel strain of Mucor hiemalis f. corticola was determined to have the highest lipase activity. The ...

Purification and characterization of extracellular a-amylase from a thermophilic Anoxybacillus thermarum A4 strain

Baltaş, Nimet; Dinçer, Barbaros; Ekinci, Arife Pınar; Kolaylı, Sevgi; Adıgüzel, Ahmet (Inst Tecnologia Parana, 2016)

alpha-Amylase from Anoxybacillus thermarum A4 was purified using ammonium sulphate precipitation and Sephadex G-100 gel filtration chromatography, with 29.8-fold purification and 74.6% yield. A4 amylase showed best performance ...

Purification of acetylcholinesterase from Halyomorpha halys (Stal) (Heteroptera: Pentatomidae) and management of control of the Pest through inhibition of the enzyme

Dinçer, Barbaros; Akpınar, Havva (Springer, 2023)

Halyomorpha halys (Stal) (Heteroptera: Pentatomidae) has brought about agricultural harm throughout the Eastern Black Sea coastline since 2017. It continues to come to a threat because there are no adequate studies on ...

Pyronin Y (basic xanthene dye)-bentonite composite: a spectroscopic study

Tabak, Ahmet; Kaya, Mehmet; Yılmaz, Nurdane; Meral, Kadem; Önganer, Yavuz; Çağlar, Bülent; Sungur, O. (Elsevier Science Bv, 2014)

The expansion by 1.43 Angstrom of basal spacing and the shift to higher frequencies of in-plane ring vibrations of the Pyronin Y molecule at 1603 and 1527 cm(-1) on the formation of Pyronin Y-bentonite composite exhibited ...

Quantum emitter interacting with graphene coating in the strong-coupling regime

Günay, Mehmet; Karanikolas, Vasilios; Şahin, Ramazan; Ovalı, Rasim Volga; Bek, Alpan; Taşgin, Mehmet Emre (Amer Physical Soc, 2020)

We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are based on solutions of three-dimensional Maxwell equations, using a boundary element method approach. ...

Quaternionic osculating curves in Euclidean and semi-Euclidean space

Bektaş, Özcan; Gürses, Nurten Bayrak; Yüce, Salim (Taylor & Francis Ltd, 2016)

In this study, the osculating curves in Euclidean space E-3 and E-4, well known in differential geometry, are studied through the instrumentality of quaternions. We inoculate sundry delineations for quaternionic osculating ...
