Title:
NOVEL ORGANIC MATERIAL-BASED NANOFLUID MATERIAL FOR IMPROVING C1 GAS CONVERSION EFFICIENCY
Document Type and Number:
WIPO Patent Application WO/2019/083316
Kind Code:
A3
Abstract:
The present invention relates to an organic material-based nanoparticle for improving mass transfer efficiency in a bioconversion process of C1 gas such as carbon monoxide (CO) and methane (CH4) and a nanofluid formed thereby. The nanofluid comprising the novel organic nanoparticle of the present invention allows gas of low water solubility to be effectively used in an aqueous solution and can be effectively used in a bioconversion process where a microorganism strain utilizes gas to afford bioconversion products while surmounting the cytotoxicity problem with nanoparticles. In addition, the novel organic material-based nanofluid of the present invention can be applied to various cell culture media for microbial conversion and is expected to improve cell growth rates and increase the usage of gas in cells, thus finding useful industrial applications.
