Pichia anomala 2.2540, isolated from soil contaminated by crude oil, degraded naphthalene, dibenzothiophene, phenanthrene and chrysene, both singly and in combination. The yeast degraded 4.5 mg naphthalene l−1 within 24 h. Phenanthrene was degraded after a lag of 24 h. When a mixture of all four polycyclic aromatic hydrocarbons was treated at either 0.1–1.6 mg l−1 or 3.1–5.3 mg l−1, naphthalene was completely degraded first within 24 h, followed by phenanthrene and dibenzothiophene after 48 h… CONTINUE READING
