To achieve prebiotic sources, nanonisation had been implemented reduce size polysaccharides nano size. In this study, two techniques were applied which water bath probe sonication. Different sonication power was used at 50 100% amplitude for 3, 6, 9, 12 15 min. maximum particle reduction Arabic gum can be...

In this work, a subtractive inhibition assay (SIA) based on surface plasmon resonance (SPR) for the rapid detection of Campylobacter jejuni was developed. For this, rabbit polyclonal antibody with specificity to C. first mixed cells and unbound subsequently separated using sequential process centrifugation then detected an immobilized goat anti-rabbit IgG SPR sensor chip. This SIA-SPR method showed excellent sensitivity limit (LOD) 131 ± 4 CFU mL-1 95% confidence interval from 122 140 mL-1....

In this work we screen...

Bacillus cereus is increasingly recognized as one of the major causes food poisoning in industrialized world. In a previous publication, sandwich ELISA developed for detection B. whole cells. The curve showed sigmoidal calibration curve, but model used was linear. This study remodels data obtained using four-parameter logistic (4PL) equation that can cover range obtained. efficiently fit by 4-PL equation. A good correlation coefficient value 0.996 indicating fitting. LOD 5.36 x104 CFU/mL...

Abstract Toxicants removal through microorganism’s action is intensely being sought due to economic reasons. The aim of this paper isolate a bacterium that able reduce molybdenum blue and at the same time can grow on detergent Sodium Dodecyl Sulfate (SDS). Biochemical analysis resulted in tentative identification as Enterobacter sp. strain Neni-13. Growth SDS showed 100 % 800 mg/L within 12 days. from media was confirmed Methylene Blue Active Substances Assay. Molybdenum reduction using...

For many years, fertilizers have been utilized in agriculture to increase the fruit yield and quality of various crops, which turn will nutritive content products. Recently, MARDI has developed a nano-fertilizer based on nanoemulsions productivity rock melon. The development nanoemulsion-based fertilizer was carried out using high-energy emulsification method significant advantages, such as enhancing solubilization active constituents while preserving biological activity. In this work,...

Heavy metals pollution has become a great threat to the world. Since instrumental methods are expensive and need skilled technician, simple fast method is needed determine presence of heavy in environment. In this study, an inhibitive enzyme assay for been developed using crude proteases from Coriandrum sativum . assay, casein was used as substrate Coomassie dye denote completion hydrolysis. absence inhibitors, hydrolysed solution became brown, while metal ions such Hg 2+ Zn , hydrolysis...

Bioremediation of monobromoacetic acid, a haloacetic continues to be recommended as acheaper and achievable method in comparison physical chemical techniques. In priorwork, we model the growth bacterium Moraxella sp. B on acid frompublished literature acquire crucial constants. We learned that Buchanan-threephasemodel via nonlinear regression using least square was most effective describe curve.
