Over the past few decades, degradative plasmids have been isolated from bacteria capable of degrading a variety of both natural and man-made compounds. Degradative plasmids belonging to three incompatibility (Inc) groups in Pseudomonas (IncP-1, P-7, and P-9) have been well studied in terms of their replication, maintenance, and capacity for conjugative transfer. The host ranges of these plasmids are determined by replication or conjugative transfer systems. The host range of IncP-1 is broad, that of IncP-9 is intermediate, and that of IncP-7 is narrow. To understand the behavior of these plasmids and their hosts in various environments, the survivability of inocula, stability or transferability, and efficiency of biodegradation in environments and microcosms have been monitored. The biodegradation and plasmid transfer in various environments have been observed for all three groups, although the kinds of transconjugants differed with the Inc groups. In some cases, the deletion and amplification of catabolic genes acted to reduce the production of toxic catabolic intermediates, or to increase the activity on a particular catabolic pathway. The combination of degradative genes, the plasmid backbone of each Inc group, and the host of the plasmids is key to the degraders adapting to various hosts or to heterogeneous environments.

“…To efficiently and economically remediate polluted sites, the ability of microorganisms to degrade PAHs is often exploited. It is known that the first step in the bacterial degradation pathway of PAHs under aerobic conditions is catalyzed by ring-hydroxylating dioxygenases (RHD; Cerniglia, 1993), whose genes are often located on IncP-7 and IncP-9 plasmids (Izmalkova et al, 2005;Sevastsyanovich et al, 2008).

Microbial communities in soil reside in a highly heterogeneous habitat where diverse mineral surfaces, complex organic matter and microorganisms interact with each other. This study aimed to elucidate the long-term effect of the soil mineral composition and charcoal on the microbial community composition established in matured artificial soils and their response to phenanthrene. One year after adding sterile manure to different artificial soils and inoculating microorganisms from a Cambisol, the matured soils were spiked with phenanthrene or not and incubated for another 70 days. 16S rRNA gene and internal transcribed spacer fragments amplified from total community DNA were analyzed by denaturing gradient gel electrophoresis. Metal oxides and clay minerals and to a lesser extent charcoal influenced the microbial community composition. Changes in the bacterial community composition in response to phenanthrene differed depending on the mineral composition and presence of charcoal, while no shifts in the fungal community composition were observed. The abundance of ring-hydroxylating dioxygenase genes was increased in phenanthrene-spiked soils except for charcoal-containing soils. Here we show that the formation of biogeochemical interfaces in soil is an ongoing process and that different properties present in artificial soils influenced the bacterial response to the phenanthrene spike.

“…Recently, several reports have appeared on the involvement of IncP-7 catabolic plasmids, which were isolated from Pseudomonas bacteria, in naphthalene or toluene/xylene degradation (Li et al 2004;Izmalkova et al 2005;Yano et al 2007). The reports indicate that IncP-7 plasmids have an important role in spreading degradative genes among bacteria, as is already known for other IncP degradative plasmids such as IncP-1 or IncP-9 (Nojiri et al 2004).…”

Conjugative transfer of the IncP-7 carbazole degradative plasmid, pCAR1, in river water samples

et al. 2007

The transfer of the IncP-7 carbazole degradative plasmid pCAR1 from Pseudomonas putida SM1443 (derived from strain KT2440) into bacteria of river water samples was monitored using a reporter gene encoding red fluorescent protein (RFP). The number of transconjugants drastically increased in the presence of carbazole, and most appeared to belong to the genus Pseudomonas. The results suggest that the presence of carbazole benefits the appearance of transconjugants belonging to the genus Pseudomonas. Intriguingly, we also detected the transfer of pCAR1 into non-Pseudomonas, Stenotrophomonas-like bacteria.
