Spirulina cyanobacteria have been widely cultivated to exploit products such as crude protein, vitamins, phycocyanin pigment... with high nutritional and pharmacological values. However, the commercialization of these is still a challenging issue due biomass cost, which mainly caused by expensive nutrients in culture medium. In this study, from 11 freshwater S. platensis strains, screening, we ...

This study investigated the effects of a new strontium-doped bioactive glass and fluoride on hydroxyapatite crystallization. We designed an in vitro experiment with calcium phosphate (CaCl2·2H2O + K2HPO4 buffer solution) different concentrations (1 mg/mL or 5 mg/mL), (0 ppm, 1 ppm ppm). Tris-buffered saline served as negative control. After incubation at 37 ? for 48 h, shape organization crysta...

In the present study, a comprehensive and systematic strategy was described to evaluate the performance of several three-way calibration methods on a bio-analytical problem. Parallel factor analysis (PARAFAC), alternating trilinear decomposition (ATLD), self-weighted alternating trilinear decomposition (SWATLD), alternating penalty trilinear decomposition (APTLD) and unfolded partial least squa...

Gastric ulcer is caused by Helicobacter pylori which also can cause peptic and gastric cancer. The rise in the global prevalence of antibiotic resistance leads to a continuous decrease eradication rate H. infection. Recently, probiotic treatment, especially Lactobacillus reuteri supplementation has proven show inhibitory effects on able reduce antibiotic-associated side effects. Yet, efficacy t...

The development of wastewater treatment industry has gradually entered the high-standard period and technology needs to be refined for different types wastewater. Traditional water quality indicators are not able explain new problems encountered in current process, especially potential removing pollutants via biological methods. This research proposed a method evaluating process by measuring ox...

In this work, the extraction and separation of bovine serum albumin (BSA) from its original matrix, i.e., serum, was performed using a novel ionic-liquid-based aqueous biphasic system (IL-based ABS). To end, imidazolium-, phosphonium-, ammonium-based ILs, combined with anions’ acetate, arginate derived Good Buffers, were synthesized, characterized, applied in development ABS K2HPO4/KH2PO4 buffe...

Pectinases find wide application in different industrial applications, e.g., textile, food, tea, paper and pulp, vegetable oil extractions, saccharification of agricultural remains, fermented drinks. Three fungal strains were screened for pectinase production. Results indicated that all are capable producing a enzyme. Penicillium chrysogenum MF318506 showed the highest activity (0.214 U/ml) on ...

Ultrafine-grained Ti31Mo alloy and Ti31Mo5HA, Ti31Mo5HA-Ag (or Ta2O5, CeO2) composites with a grain size of approximately 2 μm were produced by the application mechanical alloying powder metallurgy. Additionally, surface was modified. In first stage, specimens immersed in 5M NaOH for 24 h at 60 °C. second hydroxyapatite (HA) deposited on sample surface. The cathodic deposition −5 V vs. open cir...
