Contract awarded for Selective medium of primary enrichment of listeria selective medium of secondary enrichment
of listeria agar for identification and isolation of listeria according to ottaviani and agosti (aloa) selective diagnostic media (palkam agar or oxford agar) medium for determination of listeria mobility
1c) the axillary bud of the prophyll of the enrichment axis generated by the flag leaf, may set a secondary enrichment
axis and so on, always with prophyllar origins (Amsler & Vegetti, 1999).
In the authors' opinion this zone is a secondary enrichment
area where the carbonation of portlandite, and secondary Ca-silicate phases, is inhibited probably due to the slow diffusion of C[O.sub.2].
CSEB (ISO) is based on lauryl sulphate tryptose broth and is used for the secondary enrichment
The property is located in the Silver Bell District, which has produced more than 176 Mt at an average grade of 0.63 percent copper from skarn, secondary enrichment
blankets, and oxide copper deposits associated with a Laramide porphyry copper system, and had 1990 reserves of 185 Mt at 0.61 percent copper.
La Grande is a system of high grade massive sulphide copper veins, around which secondary enrichment
halos up to 50 m developed.
In the 1950s the Anaconda subsidiary, Chile Exploration Co., carried out more detailed exploration which indicated the potential for the existence of a secondary enrichment
Developed as a modification of UVM medium made according to ISO 11290, Fraser Broth is a secondary enrichment
broth for the isolation of Listeria spp.
On many hydrothermal deposits this concern will apply to the secondary enrichment
zone (if there is one).
Since October 1991, drilling has been concentrated at Ujina: reserves so far indicated total 100 Mt of secondary enrichment
mineralisation over 80 m thick, grading around 2% copper.
This highly effective medium allows enrichment to be performed in a single 18 hour incubation, eliminating the need for a secondary enrichment
Production of large nuggets from Venezuela is less-documented, but secondary enrichment
in near-surface workings is common.
