System biotechnology

The immediate application of phototrophic bacteria in biotechnological systems of H2 generation is not possible due to many scientific and technological problems. Some of them... 

Recent developments in software add a powerful tool to the armament of molecular biotechnology systems. The software systems are capable of analyzing...

The modern methods of three dimensional microfabrication have lead to the development of extremely miniaturized chemical and biotechnological systems. These so called microreactors represent novel approaches in respect of production flexibility and chemical reactions not yet applied in chemical processing. This has stimulated world-wide research in this field so that the technical feasibility of such devices has been demonstrated in the laboratory scale. 

The advantages of microorganisms, which are used extensively in biotechnology systems, are as follows ... 

When isolated biochemical catalysts (enzymes) or specially selected cultures of micro-organisms are to be used and more precisely defined reaction conditions are required, the biotechnological system demands a better controlled environment. Modem biotechnology, therefore, can be addressed as a refinement and further development of spontaneous fermentation with raw material inherent organisms. 

In any case it is important to note that H2 evolving culture must be nitrogen-limited. Deficiency of another element(s) will transfer culture to the double-limited state which is not favorable for H2 production (Tsygankov et al., 1996). However, a requirement for excess of macro- and micro-elements is not considerative for the biotechnological systems since many... 

Whey from the dairy industry is a waste product. Research is being conducted on biotechnological systems for upgrading lactose in whey to human health-care and cosmetic products. 

Special consideration is given to the effects on the increasingly better understood biological, biochemical and genetic networks as well as the chemical and biotechnological systems of manufacture, lecoveiy and formulation.

The first compound to be produced commercially in a biotechnological system was shikonin by Mitsui Petrochemical Industries. Shikonin is a red dye used in cosmetics. Currently, several pharmaceutical companies around the world produce plant secondary terpenoids in biotechnological systems, one of the most... 

Compared to biotechnological systems based on undifferentiated cultures, the advantages of hairy root cultures are ... 

The possible occurrence of these gases, which may be in small amounts, in chemical, technological, and biotechnological systems and the concern over pollution justify an indication of the positions of the R-lines in the spectrum. Apart from nonreversible interaction with water, in every example the Na value for water is less than that for any other examined liquid and is far removed from the respective R-line the absorption coefficient for CF4 (bp gives Ncf4 =...
