epigeic earthworm used in vermicomposting processes. Comparing initial wet olive cake and wet olive cake inoculated with Eisenia fetida catechol dioxygenase activity is detected. The catechol-dioxygenase apppears to be due to high microbial activity, catechol-dioxygenase is only detected when a vermincomposting process takes place on the wet olive cake.

physiological function

catechol-2,3-dioxygenase contributes to quinone resistance
physiological function
-
overexpressing TodE is necessary to allow Pseudomonas putida strain F1 to grow on styrene
physiological function
-
catechol 2,3-dioxygenases play a role in the degradation of monoaromatic hydrocarbons
physiological function
-
both the ortho- and the meta-degradation pathways are functional in presence of phenol. However, the activation of the catechol 2,3-dioxygenase, only when phenol is present, and the accumulation of only intermediary compounds related to this pathway lead us to the conclusion that the aromatic ring is preferentially opened through the meta-pathway
physiological function
-
isolate A235 shows high phenol degradation capacity on solid and liquid media containing 20% (w/v) NaCl and phenol as sole carbon and energy source. Degradation of phenol is achieved through a meta-cleavage pathway involving catechol 2,3-dioxygenase
