- Abstract:
- ... In this study, a novel biocomposite beads is developed by gelling sodium alginate (ALG) solutions in acid whey (Aw). The formation of alginate-whey biocomposite (ALG-Aw) was confirmed by FTIR analysis where the corresponding spectrum showed the presence of characteristic absorption bands of both ALG and Aw. SEM analysis showed the presence of lactic bacteria immobilized in the alginate matrix lead ...

Lytic polysaccharide monooxygenases (LPMOs) have attracted vast attention because of their unique mechanism of oxidative degradation of carbohydrate polymers and the potential application in biorefineries. This study characterized a novel LPMO from Myceliophthora thermophila, denoted MtLPMO9L. The structure model of the enzyme indicated that it belongs to the C1-oxidizing LPMO, which has neither a ...

- Abstract:
- ... Haemophilus influenza (H. influenza) is a gram negative coccobacillus pathogenic microorganism. H. influenza produces beta-lactamases, and it is also able to modify its penicillin-binding proteins, so it has gained resistance to the penicillin family of antibiotics. In this work, a novel sensitive approach was established for the monitoring of H. influenza using DNA based bio-assay. For the first ...

As the active HBsAg used in Hepatitis B vaccine production is in the form of virus-like particle (VLP), therefore the time and stages at which the VLP assembling happened through the process would be important.

- Abstract:

Cyclophilins are chaperones found in both eukaryotes and archaea, which catalyze the reversible cis-trans isomerization around peptidyl-prolyl imide bond (PPIase activity). Eukaryotes possess multiple cyclophilin genes, many of which have acquired divergent ...

While dextran sulfate (DXT) was chosen in most studies as the polyanion for nanoplex formation, drug-DXT nanoplex demonstrated poor long-term physical stability for drugs with high crystallization propensity, such as ciprofloxacin (CIP). Herein we hypothesized that amorph ...
