“…However, the presence of ndo genes or the capacity for naphthalene degradation should not be excluded, because the primers employed do not cover the high diversity of known ndo genes [23] and especially not all the pathways involved in hydrocarbon degradation [44]. Moreover, catabolic genes, like ndo, are frequently found in mobile genetic elements, namely plasmids [62]. The lack of a selective pressure that favors the maintenance of these catabolic genes may have led to their loss during the experiment.…”

“…These so-called catabolic plasmids (for a review see Sayler et al, 1990) provide their hosts with the advantage of a broader growthsubstrate spectrum. To be competitive in a certain niche, however, the advantage must be big enough to compensate for the costs of maintenance and expression of the catabolic plasmid.…”

Pseudomonusputidu mt-2, harbouring the TOL plasmid pW WO, was grown in chemostat culture under succinate-, sulphate-, ammonium-or phosphate-limitation at different dilution rates. The fraction of mutant cells lacking the plasmid-encoded enzymes for the degradation of toluene and xylene (TOL-cells), was determined. Genetic analysis revealed that all TOL-cells isolated harboured partially deleted plasmids, lacking the TOL catabolic genes. The growth-rate advantage of the TOL-cells was quantified from the kinetics of their increase as a fraction of the total population. At a dilution rate of 0.1 h-l no growth-rate advantage of TOL-cells was found when phosphate or ammonium were limiting. Under sulphate-limitation, ingrowth of TOL-cells was evident but did not follow a straightforward pattern. Under succinate-limitation the growth-rate advantage was the highest, particularly at low dilution rates (about 50% at D = 0-05 h-l). In phauxostat culture, at the maximal growth rate, the growth-rate advantage of TOL-cells was less than 1 %. The specific activity in TOL+ cells of the plasmidencoded enzyme catechol 2,3-dioxygenase was relatively high at a low growth rate.

“…The plasmid carrying genetic system for the degradation of a complex compound is referred to as the catabolite plasmid. In the literature till date, the catabolite plasmids bearing several bacterial species viz, Klebsiella, Moraxella, Rhodococcus, Pseudomonas, Flavobacterium, Alcaligenes, Acinitobacter and Arthrobacter are reported (Sayler et al, 1990). Recently, the co-metabolic degradation of organophosphorus compound dimethoate is reported by bacterium Raoultella sp.…”
