Potential biotechnology

Molecularly imprinted polymers (MIPs) are of growing interest for their potential biotechnological applications. Recently, the templating processes with living yeast cells were reported107 for the preparation of ordered and... 

The simple-looking task is solved by a sophisticated molecular mechanism. Hydrogenase is a metalloenzyme, harbouring Ni and Fe atoms. Like most metalloenzymes, hydrogenases are extremely sensitive to inactivation by oxygen, high temperature and other environmental factors. These properties are not favourable for several potential biotechnological applications.

The role and function of SM as well as their potential biotechnological applications are the topic of Volume 39 of Tknnual Plant Reviews, Functions of Plant Secondary Metabolites and Biotechnology. 

The peroxidase field was reviewed in depth in two volumes published in 1991 (11). Enzymes belonging to the superfamily of plant, fungal, and bacterial peroxidases were reviewed in Volume II and additionally in two other texts (12,13). General reviews on heme peroxidases since 1992 include those published by Poulos and Fenna (14) and Poulos (15), which highlight structural comparisons and potential biotechnological applications of peroxidases, respectively. One of the present authors also surveyed the heme peroxidase literature in a review published in... 

First, the delivery of any such potential Biotechnological Revolution in agriculture lies squarely in the domain of Chemical Engineering. Second, in tomorrow s world we cannot leave all the issues to science and technology the social/ethical/political questions will need full and open airing.

Since plant tissue culture has become a potential biotechnological field, it is justified to investigate the past of this valuable tool. As early as 1839, Schwann suggested that plant cells should be considered totipotent. This means that each living cell of plant tissue is able to develop into a whole organism provided the cell is maintained in a proper environment, esp. with respect to nutrition.

Early work by Seebach and coworkers demonstrated that both P-peptides and y-peptides are resistant to proteolysis. The incorporation of even one p-peptide residue can impart significantly improved proteolytic resistance to otherwise natural peptides. Several bacterial p-peptidyl aminopeptidases capable of cleaving p-peptides have recently been identified, and while such enzymes would not hinder pharmaceutical applications of p-peptides since they are not present in humans, it is quite intriguing that they may enable the selective cleavage of p-peptides in the presence of a-peptides, and thereby expand the potential biotechnological roles of P-peptides. ...

Enzymes when hosted in reverse micelles can catalyze reactions that are not favored in aqueous media. Products of high-added value can be thus produced in these media. The potential technical and commercial applications of enzyme-containing microemulsions as microreactors are mainly linked to their unique physicochemical properties. The potential biotechnological applications of microemulsions with immobilized biocatalysts such as enzymes are described in Chapter 12 by Kunz and coworkers and in Chapter 13 by Xenakis and coworkers.

Cell-polymer interactions of fluorescent polystyrene (FPS) latex particles coated with thermosensitive PNIPAM and poly(N-vinylcaprolactam) or grafted with poly(ethylene oxide)-macromonomer were analyzed by Vihola et al. [131] by modifying the surface of the FPS particles with the thermosensitive polymer gels or with poly(ethylene oxide)-macromonomer grafts. In all the cases, the FPS were surface-modified by polymerization of both thermosensitive monomers and macromonomer onto the surface of the fluorescent particles. The final surface-coated particles have potential biotechnological applications in the form of either stealth-carrier behavior or enhanced cellular contact.
