1 74 Team of Biomass Engineering
2 Team of Biomass Engineering Brief Introduction The team of biomass engineering focuses on the key scientific problems in the production of bio-based energy, materials and chemicals from non-grain biomass, especially from lignocellulosic biomass. The target is to establish green technology platforms for biomass utilization, provide technical support and theoretical basis for industrialization, and consequently improve the international competitiveness in biomass engineering research. The group is engaged in the major research areas including: 1) component fractionation and directional conversion technologies of lignocellulosic biomass, 2) process engineering for the integrated production of bio-based energy, materials and chemicals from biomass, 3) new process on natural medicine production from medicinal plants, and 4) biodenitrification, bio-desulfurization and bio-removal of heavy metal with petroleum microbe. Research Activities 1. Key Technologies and Demonstration for Straw Ethanol Fermentation Coupled with Solid State Enzymatic Hydrolysis Controversies on bioethanol production from straw have mainly surrounded the economical feasibility and environmental impacts for decades. This is primarily caused by lack of efficient systematic integration of the related specialties regarding to the characteristics of straw. To achieve an economical and environmentally-friend bioethanol production system from straw, a number of breakthroughs are needed, not only in individual process, but also in the balance and integration of these processes. An assembled pretreatment technology by coupling steam explosion with mechanism carding and alkaline hydrogen peroxide was invented which can degrade 85.08% and 97.6% of hemicellulose and lignin, respectively. The cost of cellulase in the straw ethanol production was decreased from 2350 to 1500 RMB/t. Finally, a demonstration production line with annual production of 3000 tons of straw ethanol was established at the cost of straw ethanol of 5500 RMB/t. 2. Industrialized Bio-refining Line for Straw with the Multi-production of Biobased Products The ultimate aim of biomass-economy is to replace the products coming from oil refineries by biomass refineries. Lignocellulosic biomass is an integrator of multifarious functionalized macromolecules coupled with complex chemical bonds. It is difficult to be economically degraded into monosaccharides and used as the raw material for biotransformation. In our group a t/a straw refining industrial production line was established at Jilin Province in In this straw refining industrialization line, butanol, acetone and ethanol are produced from the fermentation of hemicelluloses, long fibers used for paper making, short fibers and lignin used for preparing polyether, phenolic resins and other products. It has the annual capacity of tons of butanol, tons of acetone and ethanol, tons of high purity cellulose. This project could receive total profit of 660 million RMB with the poly-production of solvent (butanol, acetone, and ethanol), phenolic resin and polyether polyols. This production line creates a new industrial refining model using straw as raw material and breaks the technically and economically long-standing problems that bothers the biomass industry. 75
3 3. Process Intensification and Integration on Gas Bio-desulfurization Bio-desulfurization is a novel technology for deeply removing hydrogen sulfide and recovering sulfur, which has many advantages over chemical method, such as simple process, easy operation and low cost. Identification on the key factors restricting the development of bio-desulfurization in order to overcome the deficiency of existing technology has been one of the most important focuses of our research. So far, we have obtained several halo-alkaline sulfide oxidizing bacteria. The mechanism of the sulfur oxidases system in them by identifying the coding genes of key enzyme and the regulation of these genes expression has been illustrated. A novel bio-desulfurization bioreactor has been designed for biogas cleaning. Owing to these achievements, a 1,000 Nm 3 /d pilot plant for biogas bio-desulfurization is going to be built. Infrastructure From 1986, IPE has been carrying out the research on biomass engineering. After development for nearly thirty years, the biomass engineering group has possessed various basic equipments and advanced analytical instruments, such as HPLC, GC, LC-MS, low field nuclear magnetic resonance, near infrared spectroscope. Moreover, several apparatus platforms for biomass engineering have been designed with the completely independent intellectual property rights, including steam explosion apparatus, liquid hot water and microwave apparatus, gas double dynamic solid-phase Fig. 1 Apparatus for biomass engineering designed by biomass engineering group [(A) Low pressure steam explosion apparatus (50 L); (B) Continuous solid-state simultaneous enzymatic hydrolysis, ethanol fermentation and ethanol separation apparatus (500 L); (C) Ultrasound extraction device for the active ingredients in plants (200 L); (D) Gas double dynamic solidstate fermentation reactor (200 L); (E) Continuous microwave pretreatment apparatus for b fermentation reactor, etc. (Fig. 1). Many types of equipment have been scaled up and used in the industrialization project of biomass. For example, the low pressure steam explosion apparatus was designed to realize the effective pretreatment of biomass without adding any chemical reagents and scaled up to 1, 5, 20, 30 and 50 m 3 in size. Gas double dynamic solid-state fermentation reactor was devised to improve the heat and mass transfer during the solid-state fermentation process and consequently enhance the fermentation efficiency. So far, it has been scaled up to 5, 50 and 100 m 3 which can realize the online parameter monitoring. The group has 27 staff members, including 6 professors, 7 associate professors, 7 assistant professors, 5 engineers, and 2 administrators. Many of them are the leading talents in the field of biomass. These entire infrastructures guarantee the successful completion of the research projects and the international advanced level of the research achievements in the biomass engineering group. 76
4 Research Progress 1. Intrinsically Porous Characteristics of Lignocellulosic Biomass and the Concept of Seepage Recalcitrance in Terms of Process Engineering As solid phase substrates, lignocellulosic biomass is characterized with complex porous media, such as porosity, surface area, and permeability. The heat and mass transfer of porous media are involved in a few major operation units of lignocellulose bioconversion. These pores are used for the transfer of fluids (Fig. 2). Based on the cognition of intrinsically porous characteristics of lignocellulosic biomass, the concept of seepage recalcitrance in terms of process engineering was proposed, and defined as the resistance of porous plant biomass to mass transfer. It is determined by porous structure parameters including pore size distribution, specific surface area, tortuosity, fractal dimension and so on. The proposed biomass seepage recalcitrance is distinct from biomass recalcitrance which would advance our understanding about the relationships between structure and enzymatic hydrolysis of lignocellulosic biomass. Moreover, for plant biomass refining, pretreatment technology would be guided with an engineering index (threshold pressure) and enzymatic hydrolysis would be intensified by overcoming the threshold pressure.

Where, (a) can represent the pores on organ level, (b) and (c) can represent the pores on cell level. By illustrating the pore size distribution of corn stalks on different levels, we can reveal the porous media nature of plant biomass.] 2. Metabolic Engineering and Fermentation Regulation for Succinic Acid Production Succinic acid, a 4-carbon dicarboxylic acid, is an important platform chemical. The fermentative production of succinic acid by microbial organisms as a green technology has the advantages of CO2 fixation and using biomass as the feedstock. However, all natural succinic acid-producing organisms have the problems of lower titers, lower yields and other byproducts from mixed-acid fermentations. In our group, a series of engineering strains with higher succinic acid yield were constructed with the strategy of metabolic engineering (Fig. 3). The highest succinic acid yield can reach 1.47 (mol/mol). The fermentation with corn stalk hydrolysate was also Fig. 3 Metabolic flux in the engineered E. coli with enhancement of HCO3 supply 77
5 carried out, which laid the basis for the development of a biorefinery process of succinic acid. On the other hand, ISPR (in situ product removal) strategy through a coupled expanded bed adsorption system was applied to eliminate the product inhibition and consequently enhance the productivity of succinic acid (Fig. 4). The cost of the novel coupled process was much lower than traditional processes in which the fermentation and purification were separated. Take operational cost as an example, it was 60%~70% at a discount. Succinic acid production cost was reduced to $/kg. Fig. 4 Efficient succinic acid production via an integrated fermentation process coupled with in situ separation. 3. Identification on Factors Affecting Biomass Utilization and New Pretreatment Technology Development Based on Liquid Hot Water and Microwave Irradiation The group focuses on biomass utilization including new pretreatment technology development, physical/chemical structure change in pretreatment process, and biomass pretreatment reactor design and lignin conversion to high value-added products. Microwave-assisted CaCl 2, coupling of microwave irradiation and ball milling, and ph value precorrected liquid hot water have been invented to realize the high temperature pretreatment under atmospheric pressure. Through investigations on the correlation between enzymatic hydrolysis and physical/chemical structure changes of biomass during pretreatment process, we found that high concentration of alkali or high temperature was necessary in dissolving or decomposing the cellulose. Appropriate pretreatment severity eliminated the effects of structural diversities in feedstocks, which led to convergence in the ethanol fermentation. Meanwhile, the continuous microwave pretreatment reactor and continuous hot water pretreatment reactor were invented. Perfect efficiency was achieved when they were used for the pretreatment of corn straw, rice straw, and Miscanthus, etc. 4. Key Technologies for Sustainable Use of Elite Medicinal Plants Fig. 5 The raw material (a) and ITS sequence of Maca (b) The increased interest in natural remedies brings great challenge of maintaining a balance between the demand of expanding market for plant-based medicines and the need to protect medicinal biodiversity. Key technologies for germplasm conservation and mass micropropagation of elite medicinal plants, and scale-up production of high-value plant-derived secondary metabolites and proteins in bioreactor systems were developed in biomass engineering group. The development of effective biotechnologies that define plant yield in terms of both biomass and medicinally active phytochemicals is, therefore, extremely important for long-term, sustainable use of medicinal plants. Taking Maca (Lepidium meyenii Walp.), a crop originated from Peru, as an example, a method based on internal transcribed spacer (ITS) sequence was built to identify Maca (Fig. 5), and the HPLC determination method of macamides was established. Based on the molecular and chemical methods, we achieved the authenticity and quality evaluation of Maca, which was useful to regulate the quality of Maca merchandises and to form the Maca industry standard. 78
6 5. Industrialized Biorefinery Lines of Biomass with Economic and Social Benefits By using the technologies achieved in our group several industrialized biorefinery lines have been established successfully in China, such as 3000 t/a straw ethanol production line (Shandong Province, China), t/a straw refining industrial production line (Jilin Province), t/a straw butanol production line (Shandong Province), etc. The t/a straw refining industrial production line was established in 2010 with annual capacity of tons of butanol, tons of acetone and ethanol, tons of high purity cellulose (producing for tons bio-based polyetherpolyol), and tons of high purity lignin (producing for tons of bio-based phenolic resin) (Fig. 6). In this project, hemicellulose hydrolysate (mainly xylose) was used for butanol fermentation instead of cellulose. Therefore, the problem of low hydrolysis efficiency of cellulose and high cost of cellulase in the traditional technology could be resolved. Meanwhile, cellulose and lignin were further converted to the bio-based polyether-polyol and phenolic resin, respectively. This project could receive total profit of 660 million RMB per year with the co-production of solvent (butanol, acetone, and ethanol), phenolic resin and polyether polyols.
