Growth experiments

Over the last few years, we have made a number of novel discoveries using reactive salt fluxes in the crystal growth experiment of mixed-metal oxides. The most important outcome that these salt-inclusion solids have demonstrated is the propensity for structure- directing effects of the employed salt. These hybrid solids have revealed fascinating solid-state structures ranging from nanoclusters to three-dimensional open frameworks of current interest. Solids featuring mag-...

Growth experiments were conducted using bacteria from oil installations with several chemicals normally used in injection water treatment. The studies revealed that some chemicals could be utilized as nitrogen sources, as phosphorus sources, and as carbon sources for the bacteria [1696]. Therefore it is concluded that the growth potential of water treatment additives may be... 

DCCD and vanadate. This indicates an active process energised by ATP. Ferrozine inhibition of Fe2+ and Fe3+ uptake implied the concerted involvement of both a Fe3+ reductase and FeoB in the uptake of iron supplied as Fe3+. It is concluded that FeoB-mediated Fe2+ represents a major pathway for H. pylori iron sequestration [189], In addition, growth experiments on the human pathogen L. pneumophila using artificial media, as well as replication studies within iron-depleted Hartmannella vermiformis amoebae and human U937 cell macrophages, provided evidence that the FeoB transporter is important for extracellular growth and intracellular infectivity [190],... 

It is difficult to predict these responses directly because they depend upon a wide range of instrumental properties in addition to the material properties of the sample. The onset of this behaviour can be explored through the use of a stress growth experiment. 

In the third study, Miyazaki and Henry (1978) carried out vapor bubble growth experiments with water drops in hot silicone oil under various pressures of argon gas. As conducted, the oil temperature was set so that the interface temperature was below the homogeneous nucleation temperature of water. When bubbles did appear, their growth was followed by...

Growth experiment of S-carboxymethyl-D-cysteine(D-SCMC) in a DL-SCMC supersaturated solution were carried out by a batchwise agitated crystallizer and the growth rates in longitudinal and lateral directions and optical purity of D-SCMC crystal were measured.

The formation of primary nanometer-sized subunits, as an intermediate step in the growth reaction, can also account for the observed induction period that was observed in the seeded growth experiments (13,38,56,57). The condensation reaction can proceed parallel to the hydrolysis reaction from the very first beginning, and still it will take a certain time (induction time) to produce the primary subunits, which then may agglomerate to form the new seed nuclei or, in the case of seeded growth, adhere to the surface of already existing particles. 

The fact that the cytochrome P-450 was induced even in the presence of NH3, which is the end product of assimilatory N-oxide reductions, suggested that it might funciton in dissimilatory N-oxide reductions. Anaerobic growth experiments with induced cells showed that reduction of nitrate to nitrite was energy yielding in F. oxysporum but reduction of nitrite to N2O was probably not (Shoun and Tanimoto, 1991). 

The clinical importance of these mutations has not been clearly demonstrated. In at least one case a drug-resistant mutant was able to grow in vitro in single-cycle growth experiments as well as wild-type HRV14 [28]. Frequently, however, drug-resistant or acid-stable mutants will not grow as well in cell culture as native virus [93].

Figure 4. Comparison between BAF(nP) data from non-limited-growth experiments and values estimated from Figures 2 and 3. Data points represent the average BAF(np)from three time points (t = 8, 16, and 30 days). The solid line is based on data from Connolly and Pedersen (27), and the dashed line is based on data from Gobas et al. (40).
