The first step in the aerobic degradation pathway is oxidative deamination with the production of catechol, with further degradation to cis, cis-muconic acid by the catechol 1,2-dioxygenase (ortho-cleavage pathway) (Aoki et al., 1984; Loidl et al., 1990; Murakami et al., 2003) or to a yellow compound, 2-hydroxymuconic semialdehyde by catechol 2,3-dioxygenase (the meta-cleavage pathway)(Fujii et al., 1997; Takeo et al., 1998a; Takeo et al., 1998b).
