Effectiveness in the ocean, although comparative tests of toxicants on G. breve cultured in an artificial medium and in sea water from Florida suggested that the Florida water contained an inhibitor that reduced the effectiveness of the toxicants (38). 

In order to put the standard SC generation scenario to a test, we compare the water SC generation simulations with analogous simulations performed using an artificial medium which is the same as the original but with a modified linear dispersion. The later is constructed such that the artificial medium exhibits self-focusing and plasma dynamics that are almost identical to those of the real medium model.

The comparison of the SC spectra obtained using the realistic and artificial water susceptibilities is shown in Fig. 13.10. The original and artificial medium spectra agree quite well in the vicinity of the excitation wavelength. However, at high frequencies the two materials produce drastically different continua. The long-dashed line shows the SC spectrum transformed by the same transformation that produced the artificial medium susceptibility from the water susceptibility. This appears to be very close to the artificial medium spectrum. This indicates that the extent of the spectrum is actually determined mostly by the linear dispersion properties of the medium.

The long-dashed line represents the spectrum edge obtained from the real water spectrum the same way as the artificial susceptibility was obtained from the original water susceptibility. The standard SC scenario predicts the same spectra for both models...

Inoculation of a sandy loam to nutrient broth and incubating for 4 days provided the mixed soil micro-flora source for 1 ml inoculation of the artificial medium. Thus 20 mg of test material was added to 20 ml of the medium in 50 ml flasks, which contained 5 g of a pancreatic digest of casein plus 1 g of dextrose per liter. After sterilization at 121° C for 15 min., the samples were inoculated with 1 ml of the soil micro-flora source and the headspace was flushed with oxygen. Controls consisted of samples tested indent-ically but containing no test material.

Fig. Ic). The inhibition of growth of the larvae in laboratory bioassays is taken as evidence of a resistance factor in corn when it can be shown that the factor occurs at a significant level in the area of the plant that the larvae feed upon. The criterion of larval growth inhibition as the measure of the contribution of a chemical factor to resistance in a plant remains at least partially subjective because it is impossible to exactly match the nutritive value of the intact plant in the artificial medium used in the laboratory bioassay. 

The organisms were grown in an artificial medium. From Shiraishi and Arai (1979). 

The fatty acid composition was determined in three isolates of P. infestans having high aggressivity to potato leaves but losing the ability to colonize the plants after several passages on artificial medium. No correlation between total EPUFA content in zoospores and aggressivity of the fungus was found in these experiments 5. ... 

It was thought probable that if these substances could be obtained ready formed, and were added to some good artificial medium (Dorset s egg medium) the bacillus would grow, and, further that these substances might be elaborated by allied micro-organisms such as the tubercle bacillus, and even stored up as reserves in their envelopes (391, pp. 69-70).. ..
