Biotechnological products, use

Ethanol is one of the oldest biotechnological products used by humans, even ancient Egyptians were drinking a sort of beer obtained by aleoholic fermentation. More reeently ethanol was involved in first- and then second-generation biofuels. The overall sustainability and economie viability of these approaches remain doubtful. However, the production of bio-ethanol in important amounts led to its eonsideration for bio-based plastics production. Thus, the dehydration of ethanol was extensively studied and improved to produce ethylene, while the further polymerization to polyethylene (PE) and utilization are well known in the plastic industty. Furthermore, bio-ethanol was also used for the production of partially bio-based polyethylene terephthalate (PET). ... 

There are still up-to-date general publications presenting the analysis of specific conditions of drying and preservation of biotechnology products used in many European countries [22-30], and also valuable publications that give an account of experimental results [31-35]. 

There are three basic methods for biotechnological production using living matter. 

The most important microbially derived surfactants are listed in Table 10. In principle, biosurfactants can be used in many food applications. Table 11 lists some important biotechnology products used in the food industry. Some of them are purified end products of fermentation, whereas others are chemically modified.

Fluorescent pseudomonads are capable of synthesizing poly(3HAMCL)s from a large number of substrates. Work on the biotechnological production of poly(3HAMCL) has focused mainly on two model systems - Pseudomonas oleo-vorans and P. putida. P. oleovorans is able to use alkanes and alkenes as substrate due to the presence of the OCT-plasmid while P. putida, which does not have this plasmid, cannot. In contrast to P. oleovorans, however, P. putida can use carbohydrates such as glucose and fructose for the production of poly(3HAMCL). 

A small number of biotechnology products are classified as medical devices and, hence, are regulated by the Center for Devices and Radiological Health (CDRH). The first approved biotech product to come under the auspices of the CDRH was OP-1 implant. Marketed by Stryker Biotech, OP-1 implant is a sterile powder composed of recombinant human oestrogenic protein-1 (OP-1) along with bovine collagen. It is used to treat fractured bones that fail to heal. The product is mixed with sterile saline immediately before application, and entails surgical insertion of the paste into the fracture.

Benefits are often more important than risks to consumers. Consumers become willing to accept products processed with specific technologies when they become convinced that these products offer significant benefits over other products. These benefits can include decreases in price as well as increases in product quality, such as taste and naturalness purity, such as reduced use of chemicals and wholesomeness, such as better nutrition (Kuznesof and Ritson, 1996). Hamstra (1995) reported that perceived benefits of biotechnology products had greater statistical influences on Dutch consumer attitudes and acceptance than perceived risks. 

Care must be taken, however, in how such products are labeled. Results of the 1991 Euro-barometer survey, for instance, reported an interesting finding related to labeling biotechnology products. Results indicated that the way biotechnology products are labeled influenced both perceptions of and attitudes toward such products. The survey was conducted using a split...

CEC is a miniaturized separation technique that combines capabilities of both interactive chromatography and CE. In Chapter 17, the theory of CEC and the factors affecting separation, such as the stationary phase and mobile phase, are discussed. The chapter focuses on the preparation of various types of columns used in CEC and describes the progress made in the development of open-tubular, particle-packed, and monolithic columns. The detection techniques in CEC, such as traditional UV detection and improvements made by coupling with more sensitive detectors like mass spectrometry (MS), are also described. Furthermore, some of the applications of CEC in the analysis of pharmaceuticals and biotechnology products are provided.
