The present study illustrates the optimization and characterization of β-glucosidase from a bacterial isolate, strain SG9. Sixty-eight different variables were first screened by one factor at a time method. The screened variable optimization was then performed by Plackett-Burman design followed by Box-Behnken response surface methodology. Thirty-one variables were screened, of which five variab...

The production of halophilic thermostable protease by Haloferax lucentensis VKMM 007 was optimized using a statistical approach. In accordance with factorial design, soluble starch, gelatin, KCl and MgSO4 were selected among 27 variables tested. Next, a second-order quadratic model was estimated and optimal medium concentrations were determined based on quadratic regression equation generated b...

OBJECTIVE To provide guidelines for the use of antenatal magnesium sulphate (MgSO4) for fetal neuroprotection of the preterm infant. OPTIONS Antenatal MgSO4 administration should be considered for fetal neuroprotection when women present at ≤ 31+6 weeks with imminent preterm birth, defined as a high likelihood of birth because of active labour with cervical dilatation ≥ 4 cm, with or without ...

Bu çalışmanın amacı; Gemlik zeytin çeşidinde sulama ile çiçeklenme öncesi ve sonrası dönemlerde yapraktan yapılan farklı gübre uygulamalarının meyve ağırlığı, eni, boyu, indeksi (boy/en), et çekirdek ağırlıkları, oranı üzerine etkilerini incelemektir.

Kaolinite is one of the principal rare earth element (REE) ion-adsorption clays that hosts a wide range elements, including Dy(III) as representative example. Ammonium sulfate typical salt used to leach REEs. Due carbon dioxide emissions which occur during ammonia production, it urgently necessary develop low environmental pollution leaching agents can replace (NH4)2SO4. MgSO4 regarded most pro...

Introduction: Galileo’s Near-Infrared Mapping Spectrometer observed distorted and asymmetric water absorption bands suggestive of H2O in a physical state other than crystalline ice on the surface of Europa.[1,2] The microstructure and related mechanical response of the crust, then, is dependent not on just pure ice, but more likely on a polyphase aggregate of ice and (a) non-ice phase(s). Labor...

Polar microorganisms produce physiologically active substances to adapt harsh environments, and these can be used as biomedical compounds. The green microalga Micractinium variabile KSF0031, which was isolated from Antarctica, produced phytol, a natural antimicrobial agent. Furthermore, several polyunsaturated fatty acids (PUFAs), including omega-3, exhibit antioxidant properties. Here statisti...
