30-4 Sanatec starts to distribute free seedlings of genome-edited “Sicilian Rouge High GABA” tomatos

Sanatec Seeds, a venture spin-out of the Japan’s University of Tsukuba, is the first company in the world to commercialize genome-edited tomatoes, “Sicilian Rouge High GABA”

“Sicilian Rouge High GABA” is a strain (variety registration pending) that contains four to five times more gamma aminobutyric acid (GABA), an antihypertensive, than its parent strain, Sicilian Rouge CF. This is the first generation (F1) hybrid created by crossing Sicilian Rouge CF with the genome edited breeding tomato line #87-17 with modified function of the tomato’s inheritant glutamate decarboxylase.

The Ministry of Health, Labor and Welfare has ruled that this tomato does not fall under the category of “genetically modified organisms” under the Cartagena Act and can be distributed to customers.

Accordingly, the marketing concept of Sanatec is in Phase 1 is to distribute seedlings, soil conditioners (microorganisms), and fertilizers to home gardeners, and in Phase 2 is to actually begin paid marketing.

31-3 Will artificial intelligence help us to healthier intestinal microbiomes?

AuB, a Tokyo startup whose president Keita Suzuki is a former member of Japan’s national soccer team, has analyzed the stool of over 700 athletes and analyzed the type, number and composition of their intestinal bacteria, combined with information on eating habits and weight gains. As a result, a new species of Bifidobacterium longum was found to prevail in those athletes  who easily gained muscles and did not gain weight, even though they ate rich meals, Equipment maker Kyocera, which sponsors the soccer club Kyoto Sanga F.C.  has now teamed up with AuB to develop a toilet-based gas sensor by which stool data of 29 players of the club will be related to their intestinal microbiomes. Using AI, it is expected to correlate odor to the composition of the microbiome and draw conclusions on the management of health and physical performance,


14-4 RIKEN-industry consortium tailors E. coli by synthetic biology to produce 1,3-butadiene from glucose

The team of Yutaro MORI at RIKEN, in collaboration with Yokohama Rubber and ZEON Co., has developed a technology to produce 1,3-butadiene from glucose by recombinant Escherichia coli. Butadiene is currently produced at 12 million t/y worldwide and over 1 million t/y in Japan from petrochemical resources. The recombinant Escherichia coli strain used in this process was bred by synthetic biology technology involving four gene deletions, five gene amplifications and introduction of four foreign genes. In addition to conventional genetic engineering, CRISPR/Cas9, was also used. Using DO–stat fed-batch fermentation, 2.13 ± 0.17 g L−1 1,3-butadiene was produced.

18-2 Hokkaido Mitsui Chemicals produces taxan intermediate by plant-cell culture in 800 l bag reactor

Using undifferentiated plant cells from the Yew tree (Genera taxus), Hokkaido Mitsui Chemicals has developed an 800 L single-use bag reactor for their cultivation. In order to prevent the slowly propagating cells from settling down, a special tube was installed at the bottom leading to circulated water flow without using an agitator. Cultured yew cells proliferation was equivalent to that in flasks and eliminated the need for a control unit for the agitator blades. As a result, the cost of equipment was reduced to about one tenth of that of a stainless steel culture tank. The project was supported by NEDO, the project house of METI. The setup is used to produce 10 deacetylbaccatin III, an intermediate for the synthesis of taxane, an anticancer drug.

Two Japanese groups challenge China’s licorice (glycyrrhizin) monopoly

Licorice root containing glycyrrhizin is the most prescribed crude drug in Chinese medicine, included in about 70% of Chinese herbs. It is also used in Kanpo, Japan’s equivalent of TCM. Glycyrrhizin extracted from licorice is 150 to 300 times sweeter than sugar, used as a sweetener and as a remedy to reinforce liver function. In addition, glycyrrhetinic acid, which is obtained by hydrolyzing the sugar chain of glycyrrhizin, is used in anti-inflammatory drugs, cosmetics, and toiletries.

In 2019, over 1000 t of licorice was imported from China to Japan at rising prices, recently 4,287 yen per kilogram (~35 €).

Recently, two Japanese group are engaged to find alternative sources for this valuable compound.

In 2013, Oji, a papermaker, established a Medical Plant Research Institute and started research analyzing the gene expression of licorice under various cultivation conditions. With a new cultivation technique, glycyrrhizic acid content was increased within a short period of 1.5 years from sowing to harvest, and demonstrated in a Hokkaido farm. Next, mechanization technology required for a ha-scale cultivation of licorice (ha scale) was established on two test farms in ​​Hokkaido. In the fall of 2020, Oji Holdings announced that licorice roots could be harvested in the t scale (dry weight).

A second approach by Toshiya MURANAKA and colleagues of Osaka University and RIKEN is based on synthetic biology, using S. cerevisiae. They cloned the CSyGT gene encoding a glucuronosyltransferase from the licorice plant, and expressed it with six other genes into yeast, enabling it to produce about 0.5 mg/L glycyrrhizin from glucose after 5 days of incubation.

Japanese Noster Co. commercializes functional fatty acid which suppresses postprandial glucose levels

The product, 10-hydroxy-cis-12-octadecenoic acid (HYA®), had originally been detected as a metabolite of dietary lipids and fatty acids by intestinal bacteria by the group of Jun OGAWA at Kyoto University. Further research at Nitto Pharmaceutical Co. had shown that this fatty acid inhibits the rise of postprandial blood glucose levels. A process has been developed by Noster Co., a subsidiary of Nitto Co., and supported by NEDO, producing HYA®-50 by reacting naturally occurring vegetable oil with lactic acid bacteria at high density, thus reducing the environmental impact of the production process and positioning HYA®-50 as a “green bioproduct”.

Osaka University team finds clue in microbiota for rheumatoid arthritis

Based on extracted DNA samples and shotgun sequencing collected from stool of 82 untreated rheumatoid arthritis patients and 42 healthy subjects, the team of OKADA Toshihiro at Osaka University School of Medicine has found that some species of Prevotella are significantly increased in the microbiome of rheumatoid arthritis patients. It could not be concluded whether the increase of Prevotella is the cause or the result of disease. However, since the stool of patients at an early stage was analyzed, the finding may be used as a risk prediction marker. As there was no significant difference in the metagenomic diversity between patients with rheumatoid arthritis and healthy individuals, dysbiosis did not seem to be related to rheumatoid arthritis.
