In-Depth Information
Two strains of yeast dominated the sample: Debaryomyces occidentalis (P1)
and Trichosporon ovoides (P19), Strain P19 had the highest TOC-decreasing
activity and was immobilized onto chitosan beads. The immobilized yeast
reduced the TOC from 1.2 x 10 3 to 3.0 x 10 2 mg of C/L per day in the fi sh
cannery wastewater (Urano et al., 2002).
