Process micro

We have seen that both the maintenance energy requirement and the P/O quotient of the process micro-organism influences the rate of product formation. In the following sections we will consider how these two factors can be determined, together with the maximum biomass yield. 

For a high-quality product, the substrate itself must be relatively pure to minimise carryover of impurities to the final product Most industrial process micro-organisms produce optimal yields of exopolysaccharides from carbohydrate and the most commonly used substrates for industrial production are ... 

Addition of antibiotics to the fermentation broth may be used to avoid problems associated with growth revertants (eg auxotrophic back mutation) ensure that genetic material (eg plasmid DNA) is maintained within the process micro-organism. 

In order to supplement micro-mechanical investigations and advance knowledge of the fracture process, micro-mechanical measurements in the deformation zone are required to determine local stresses and strains. In TPs, craze zones can develop that are important microscopic features around a crack tip governing strength behavior. For certain plastics fracture is preceded by the formation of a craze zone that is a wedge shaped region spanned by oriented micro-fibrils. Methods of craze zone measurements include optical emission spectroscopy, diffraction... 

Based on the micro-electronics fabrication process, Micro-Opto-Electro-Mechanical Systems (MOEMS) have not yet been used in astronomical instrumentation, but this technology will provide the key to small, low-cost, light, and scientifically efficient instruments, and allow impressive breakthroughs in tomorrow s observational astronomy. Two major applications of MOEMS are foreseen ...

The same features were found for pilot-size micro-reactor operation (Figure 4.59). Brightness and transparency were the same and color strength could be increased to 149% [55]. The mean particle size was even set to a lower value compared with the laboratory-scale processing (micro reactor, D5Q = 90nm, s= 1.5 ... 

The performance of the Sonogashira reaction is claimed to be the first example of a homogeneously metal-catalyzed reaction conducted in a micro reactor [120], Since the reaction involves multi-phase postprocessing which is needed for the separation of products and catalysts, continuous recycling technology is of interest for an efficient production process. Micro flow systems with micro mixers are one way to realize such processing. 

Kinetic isotope effects during microbial processes. Micro-organisms have long been known to fractionate isotopes during their sulfur metabolism, particularly during dissimilatory sulfate reduction, which produces the largest fractionations in the sulfur cycle... 

Symyx, one of the pioneers in combinatorial screening, presented a chemical processing micro system in 2000 for the screening of 256 catalysts on a silicon or quartz glass wafer [63], The reactant flow was distributed by a micro structured manifold etched into a silicon wafer (Figure 3.34).
