The effect of probiotic use in chicken production has also been studied by several groups. For example, Kralik el al. (2004) have studied the effect of adding probiotics to the drinking water of avian broilers. They reported an increase of live weights of broilers, an improvement in feed conversion ratios and lower population densities of the pathogenic bacteria E. coli and Staphylococcus aureus in the intestinal contents. 

RNA but instead would have to start over. However, an encounter with certain DNA sequences results in a pause in RNA synthesis, and at some of these sequences transcription is terminated. The process of termination is not yet well understood in eukaryotes, so our focus is again on bacteria. E. coli has at least two classes of termination signals one class relies on a protein factor called p (rho) and the other is p-independent.

Philip Evans and his coworkers have determined the crystal structures of phosphofructokinase from two species of bacteria, E. coli and Bacillus stearothermophilus. By crystallizing the enzyme in the presence and absence of the substrate and several allosteric effectors, they obtained detailed views of both the T and R conformations. This work has led to an explanation of why phosphofructokinase appears to be constrained largely to all-or-nothing transitions between these two states, rather than adopting a series of intermediate conformations.

This is interesting for fragile objects such as mammalian cells [13], which should not be squeezed between glass surfaces, and for motility experiments as the displacement of the cells is not limited vertically. The largest available magnification, depending upon the ocular-lens combination is about x 1500. This value limits the observation of the smallest cells such as non filamentous bacteria (E. coli) or plankton.

Besides expression in insect cells and bacteria (E. coli) a variety of other expression systems are used like mammalian cells, V79 hamster cells, systems in yeast (Friedberg 1999 and references cited therein). High expression level and/or high yields in producing cells are achieved in baculovirus and E. coli. Therefore, these systems are nowadays in broad application in the industrial environment, also because of their commercial availability. 

Table 2 Percentage of charged amino acids and (G - - C) content of 10 hyperthermophilic archaea (A), 2 hyperthermophilic bacteria (B), and mesophilic bacteria E. coli. A strong prevalence of lysine over arginine in proteomes of hyperthermophiles is obtained for nine organisms. A bold font marks the exception from the general trend...

Figure 5. Disk assays of plant ALS genes expressed in bacteria. E. coli expressing a wild type or a herbicide resistant ALS gene were tested for their ability to grow in the presence of the active ingredients from two commercial herbicides.

The 2 Fe 2S plant type ferredoxins, MW 12,000 dal ton, Em = —430 mV, were first isolated from chloroplast and photosynthetic bacteria. Similar proteins have been purified from the bacteria E. coli (264) and Pseudomonas putida [ putidaredoxin , Em7 = —235 mV, (275)] and from mammalian adrenal cortex mitochondria [ adrenodoxin Em = — 367 mV, 13,100 dalton (165)] among other sources.
