摘要:
Provided is a production method of a lipophilic bioactive substance, which includes mixing an aqueous suspension of a microbial cell containing the lipophilic bioactive substance or a microbial cell homogenate thereof and an organic solvent in the presence of a particular surfactant, and extracting the lipophilic bioactive substance into the organic solvent phase. This production method enables extraction without using special dehydrating, drying facility, and without causing a decrease in the yield due to degraded separability between solvent and fungus body component, as well as efficient industrial production.

PROBLEM TO BE SOLVED: To provide a treatment method for a cellulose-containing material that is more practicable to decompose cellulose more using an ionic liquid. SOLUTION: The cellulose-containing material is brought in contact with the ionic liquid 1-butyl-3-methylimidazolium acetate to impregnate the cellulose-containing material with the ionic liquid. The structure of the cellulose is alleviated by such a treatment, and is efficiently decomposed by a cellulase. COPYRIGHT: (C)2011,JPO&INPIT
