Ralstonia pickettii

Toluene/o-xylene monooxygenase in P. stutzeri strain 0X1 carried ont snccessive monooxygenation of o-xylene (Bertoni et al. 1998), and the tolnene-4-monooxygenase of Pseudomonas mendocina KRl and tolnene-3-monooxygenase of Ralstonia pickettii PKOl can hydroxylate benzene, tolnene, and o-xylene (Tao et al. 2004 Vardar and Wood 2004). [Pg.108]

The poly(HA) depolymerases of the bacteria Alcaligenes faecalis (strains AE122 and Tl), Comamonas acidovorans, Comamonas testosteroni, Comamonas sp., Pseudomonas fluorescens, Pseudomonas lemoignei, Pseudomonas stutzeri, Ralstonia pickettii, Streptomyces exfoliatus, and of the fungi Paecilomyces lilaci-nus, Penicillium funiculosum, and Penicillium pinophilum have been purified and characterized (for details see Table 1). Poly(HA) depolymerases share several characteristics ... [Pg.293]

Radosevich et al. (1995a) studied atrazine mineralization by indigenous microbial communities inoculated with a Ralstonia pickettii (previously strain M91-3 (Stamper et al., 1997)) in surface soil and subsurface zones. The authors found that the mineralization rate constants (k) and overall mineralization (P-max) were higher in microcosms that were not sterilized prior to inoculation, indicating that the native microbial populations in the sediments were contributing to the overall release of 14C02 from (U-14C -ring)-atrazine and (14C -ethyl)-atrazine. They also concluded... [Pg.313]

Radosevich et al. (1995b) studied the biodegradation of binary and ternary mixtures of atrazine, simazine, and cyana-zine using a pure culture of the atrazine-degrading bacterium Ralstonia pickettii (previously strain M91-3). While the bacterium used atrazine and simazine indiscriminately, cyanazine degradation was slow and delayed until the depletion of the two other herbicides. There was no apparent effect of other commonly used herbicides on the rate of atrazine... [Pg.315]

Less is known about the pathways of PAH degradation by co-cultures than about the pathways of degradation by individual bacteria and fungi (Juhasz Naidu, 2000). Four bacteria Pseudomonas aeruginosa, Pseudomonas cepacia (=Burkholderia cepacia).

In addition to these well-known organisms it has however been demonstrated that other organisms (e.g. Burkholderia cepacia, or Ralstonia pickettii) can cause infection when present in pharmaceutical preparations. For this reason the concept of objectionable organisms was originally introduced in the USA. Objectionable micro-organisms are defined as contaminants that, depending on the... [Pg.400]
