The presence of alkene monooxygenase activity in extracts of vinyl chloride-grown M. aurum LI, combined witli the observation that vinyl chloride degradation can be competitively inhibited by the addition of ethene or propene, which are both oxidized to the corresponding epoxides, is strong evidence that the initial step in vinyl chloride metabolism is indeed catalyzed by alkene monooxygenase (Figure 3) [25].

Combourieu B, P Besse, M Sancelme, H Veschambre, AM Delort, P Poupin, N Truffaut (1998) Morpholine degradation pathway of Mycobacterium aurum MOl direct evidence of intermadiates by in situ H nuclear magnetic resonance. Appl Environ Microbiol 64 153-158. 

This has received widespread application, and a single example has been chosen as representative. The pathway for the degradation of morpholine by Mycobacterium aurum MOl sadMycobacterium strain RPl was examined using whole cells, and this confirmed its identity to the one that had been proposed earlier for M. chelonae (Combourieu et al. 1998 Poupin et al. 1998).

Wear and friction properties. Aurum grades, where Mitsui s unique compounded materials are based on the proper selection of matrix, fillers, and additives, have excellent wear and friction properties. Aurum has both outstanding wear resistance and low friction even at 302°F (150 C) in dry conditions. The PV limit, which can show the maximum capability of high load and high speed, is the highest of all thermoplastics in dry environments (100 kpsi m) (Table 10.4).

Rather than full names, scientists identify elements with one- or two-letter symbols. Some common elements and their symbols are carbon, C oxygen, O nitrogen, N hydrogen, H chlorine. Cl and, sulfur, S. These chemical symbols are derived from the letters of the name of the element. The first letter of the symbol is capitalized, and the second (if applicable) is lowercase. Symbols for some elements known from ancient times come fiom earlier, usually Latin, names for example, Cu from cuprum (copper), Ag from aurum (gold), and Fe from/ern[Pg.12]
