Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

Advanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Production of mannan-degrading enzymes

Biotechnology Letters, 1988
Production of mannanase by four hemicellulolytic microorganisms was studied. The highest mannanase activity was produced byBacillus subtilis. β-Mannosidase and α-galactosidase were not detected inB. subtilis culture filtrate. The hydrolysis of galactomannans was limited by the increasing degree of substitution of the substrate. No monomeric sugars were

Enzymatic Processes and Enzyme Production

Applied Biochemistry and Biotechnology, 1999
Production and use of enzymes is changing dramatically through innovations in gene expression and protein engineering. Since the establishment of these technologies, scientists and engineers deal with a noticeably different set of challenges in process development.

Modeling of enzyme production kinetics

Applied Microbiology and Biotechnology, 2007
Models of single cells, cell populations, and cultures can be most useful in organizing information in a comprehensive system description, as well as in optimizing and controlling actual production operations. Models discussed in this article are of various degrees of biological structure and mathematical complexity.

Enzymic mechanisms of superoxide production

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1991
The realization that superoxide, and other reactive oxygen species, is produced in significant quantities in biological systems is a relatively recent one and the nature and purpose of the radical-generating systems is in most cases, only beginning to be understood. It is the purpose of this review to describe the known biological sources of superoxide,

Production of Enzymes

2017
The first step in enzyme production is the selection of the enzyme source. Enzymes can be derived from microorganisms through fermentation processes, as well as plant and animal sources. Table 3.1 presents industrially important enzymes and their sources.

Proteolytic Enzymes for Peptide Production

2003
1. I n t r o d u c t i o n There are three main reasons why a protein chemist might wish to cleave a protein of interest into peptide fragments. The first reason is to generate, by extensive proteolysis, a large number of relatively small (5-20 residues) peptides either for peptide mapping (see vol.
