(57) [Summary] [Structure] The oil- and fat-containing wastewater is treated using oil- and fat-assimilating yeast belonging to the genera Hansenula, Kluyveromyces, Candida, and / or Trichosporone. [Effect] The yeast is not only excellent in assimilating fats and oils, but also excellent in cohesiveness and adhesiveness, so that the yeast density is increased and the wastewater can be treated very efficiently. |
