Oxidation of benzene to phenol, catechol, and 1,2,3-trihydroxybenzene by toluene 4-monooxygenase of Pseudomonas mendocina KR1 and toluene 3-monooxygenase of Ralstonia pickettii PKO1

Article Abstract:

The consecutive hydroxylations led to the invention of toluene 4-monooxygenase (T4MO) of Pseudomonas mendocina KR1, toluene 3-monooxygenase (T3MO) of Ralstonia pickettii PKO1 and toluene ortho-monooxygenase(TOM) of Burkholderia cepacia G4 that changed benzene to phenol, catechol and 1,2,3-trihydroxybenzene. The very heavy liquid chromatography and mass spectrometry together were used to discover the catechol and 1,2,3-trihydroxybenzene products.

Modification of spatial distribution of 2,4-dichlorophenoxyacetic acid degrader microhabitats during growth in soil columns

Article Abstract:

The spatial distribution of 2,4-dichlorophenoxyacetic acid (2,4-D) degrader microhabitats as a function of 2,4-D degrader abundance is investigated by using a soil microsampling strategy combined with a mathematical spatial analysis. The findings indicate that the characterization of bacterial microscale spatial distribution is relevant to microbial ecology studies.
