Special Priority Technology Area

White Biotechnology

Outline of the area

It is expected that the creation of chemicals from biomass by the white biotechnology will largely contribute to the reduction of CO2 emission in light of carbon neutral and energy-saving. In order to develop a practical production process of the biomass based chemicals, it is extremely important to establish the fundamental technologies in the based chemical industries such as (i) efficient separation of objective biomass components, (ii) chemical-engineered and biological-engineered conversion into core chemicals, and (iii) synthesis of high performance polymers and utilization thereof. An innovative elemental technology in the throughout process for producing high added-value chemicals from biomass will be developed to establish the biomass-based chemical industry.

Operationally we cooperate not only within the ALCA technology area but also with other JST programs. In addition, in order to effectively promote the cooperation among the projects with “Technical development of producing process of chemicals from inedible plants” in NEDO, a joint meeting comprising JST, NEDO and concerned parties for the project are established.

In the ALCA white biotechnology, attention is focused on the polymer material as a final product. We promote development of synthesis and a material design for high polymer properties such as high thermal resistance, high strength and also the development of a process for effectively producing a monomer chemical. Operationally, this technology area consists of three types of the team type, the elemental technology type and the Specific technology type. The research and development on "vertical integration type team research", "elemental technology research for solving the technological bottleneck" and "next-generation cellulose fiber" is mainly conducted for 5 fiscal years in each type.

Yukari Ohta
Deputy Group leader, Research and Development Center for Marine Biosciences, Japan Agency for Marine-Earth Science and Technology

Development of bioprocess using marine microbial enzymes for efficient lignin degradation and catalytic generation of super-urushiol from lignin monomers

The non-food biomass containing lignin is pre-treated with an environmental harmonized type approach. By using the so-obtained product, phenyl propanone aromatic monomers are selectively manufactured by using the set of enzymes of marine microorganisms. Further, the monomers will be functionally developed into a “super urushi material” by chemical catalysts.

Yuya Tachibana
Assistant Professor, Faculty of Science and Technology, Gunma University

Development of highly functional polymer using structural characteristics of furan ring

As furfural having furan ring is fatally produced from cellulose and hemicellulose due to the cost competitive edge, the polymer having furan ring would be produced from biomass. We are developing the "bio-based" highly functional polymer with the addition of the peculiar function using the structural characteristics of furan ring.

Extraction and Utilization of Lignin via Sustainable Process

Kazuhiro Shikinaka
Senior Researcher, Research Institute for Chemical Process Technology, National Institute of Advanced Industrial Science and Technology

Extraction and utilization of lignin via sustainable process

In this program, we will prepare sustainable yet effective method for utilization of lignnocellulosic biomass. The effective extraction of lignin and polysaccharides will be achieved by ultrafine bead milling and enzymatic saccharification for plants that never needs some toxic reagents. Furthermore, the obtained lignin will be used as materials with non-flammable, shape memory, and ultraviolet absorption characteristics. In the future, we aim a creation of "Agricultural Industry" in which polysaccharide and lignin of plants are used as sugar/alcohol and high performance polymer, respectively.
