Metabolomics Group
Introduction

Metabolomics Group focuses on developing highly efficient whole-cell catalysts, processes, and types of equipment for the industrial conversion of low-value lignocellulosic biomass and artificial polymer wastes to high-value-added bioproducts, including biofuels, single-cell proteins, single-cell oil (DHA, EPA, ARA), lignin-based material, cellulose nanomaterials, and biodegradable plastics. Our general research strategy heavily engages in the development of clean pretreatment methods for agro-wastes, genetic engineering of cellulosome-producing microbes (such as Clostridia thermocellum) and oil-producing microbes (such as Aurantiochytrium sp.), structure-function analysis and rational engineering of industrial proteins, metabolite and metabolic flux analysis, and finally, the equipment and fermentation process design and optimization for industrial production.

Director of Center/Group
Prof. CUI Qiu
Professor CUI Qiu received his Ph.D. degree in Molecular Biology at the Institute of Biophysics CAS in 2004 and worked at the University of Wisconsin-Madison from 2004 to 2008. Since 2009, Dr. Cui received funding from the "Hundred Talents Plan" of the Chinese Academy of Sciences and began to work as the group leader of the Metabolomics group of Qingdao Institute of Bioenergy and Bioprocess (QIBEBT). The central theme of his research focuses on critical features and bottlenecks in the high-value-added bioconversion of lignocellulosic feedstocks. He has obtained several patent authorizations and published over 70 papers in well-known academic journals, including Nature Biotechnology, Nature Communications, Biotechnology Advances, Nucleic acid Research, and Science Advances. In the past years, he received fundings from NSFC, MOST, CAS, and other institutions. Besides, he pioneered the cooperation with companies in the institute and has constructed large-scale pilot demonstrations via long-term industrial corporations.
