18-11 Green Earth Institute uses Corynebacterium resting cells to prepare green chemicals from formaldehyde

In an artificial metabolic system, the formaldehyde is added via aldolase, to appropriate cosubstrates forming 2,4-dihydroxybutyric acid (DHB), homoserine (hSer), and 1,3-propanediol (PDO). As an aldolase, hpal from Escherichia coli was used. It accepts also other aldehydes. The study is considered a proof of principle that high-cell density cultures of resting cells of C. glutamicum can be used to form valuable compounds from toxic precursors such as formaldehyde or phenol (as shown in earlier work on catechol). Metabolic engineering was not rigorously done, yields were not optimised, and by-products occurred.

18-11 Japan reports progress on transgenic pollen-free cedars

The Forest Research Institute’s Forest Biotechnology Research Center (Hitachi City, Ibaraki Prefecture) reports progress on the development of a pollen-less cedar by genome editing of “seminal trees” which grow fast and straight. In the transgenic plant, a single nucleotide has been deleted by CRISPR/Cas9 in the gene responsible for the outer wall of the pollen, inhibiting the production of mature pollen in male flowers. The genome-edited cedars are crossed with wild-type individuals to remove the foreign genes encoding Cas9 and guide RNA, and the resulting seeds contain no foreign genes. Pollen-free cedars could reduce the frequent pollen allergies in Japan by gradually substituting present cedar trees. The institute plans for regulatory submission in 2026.

1-11 Genome-edited tiger puffer fish accepted as food in Japan

Regional Fish Co., Kyoto, has received acceptance from the Ministry of Agriculture, Forestry and Fisheries and the Ministry of Health, Labor and Welfare for sales of genome-edited tiger puffer fish. In the genome-edited fish strain, a leptin receptor reducing appetite was removed, leading to growth at double speed and improved feed utilization efficiency. The high-growth tiger puffer is 1.9 times larger on average and 2.4 times larger than wild-type tiger puffer bred for the same period. It is said that it will be in a state of constantly overfeeding, but it will not become obese, and an edible part with the same composition as the wild type individual is obtained.

This is the second product of Regional Fish Co., following edible red sea bream.

26-10 Japan’s „Green Innovation Fund“ launches construction of „zero-emission“ ships and a supply chain for hydrogen and ammonia fuels

NEDO, the project house of METI, will launch a 32 billion JP¥ (242 million €) program on „next generation ships“, which includes the development of engines fueled by hydrogen and ammonia. In the future, „zero-emission ships“ will emit virtually no greenhouse gases in their operation. According to NEDO, international shipping accounts for about 2.1% of global CO2 emissions. Hydrogen- and ammonia-fueled ship engines have not yet been developed worldwide due to technical issues such as improving combustion control technology. Hydrogen and ammonia, which are gaseous at normal temperatures and pressures, larger storage volumes than conventional fuels and the issue of a „methane slip“ in LNG-powered ships. 

The program will include 4 projects:

  • Development of marine hydrogen engines and marine hydrogen fuel tanks
  • Development of ships equipped with domestic ammonia-fueled engines
  • Integrated project of ammonia-fueled ship development and social implementation
  • Development of technology to reduce methane slip from LNG-fueled ships by improving catalysts and engines

The project consortium will comprise

Kawasaki Heavy Industries, Yanmar Power Technology, Japan Engine Corporation, Japan Shipyard Corporation, IHI,  ITOCHU Corporation Mitsui E&S Machinery, NS United Shipping Corporation, Hitachi Zosen Corporation

18-9 Japan permits marketing of genome-edited fish

In the red sea bream, 14 bases of the myostatin gene suppressing muscle hyperplasia were deleted, using CRISPR/Cas technology. The average amount of the edible portion was increased about 1.2 times, and the ratio of weight gain to ingested feed improved by 14%. Since the bone volume is reduced by about 31%, it is thought that the energy to make bones goes to the muscles. Pertinent research was done at Kinki University and Kyoto University, and commercialization is by Regional Fish https://regional.fish/en/, started by crowd-funding. The Ministry of Agriculture and Fisheries confirmed that the fish is not subject to the Cartagena Law, and the the Ministry of Health, Labor and Welfare confirmed that the fish conform to the Food Sanitation Law. Within a crowdfunding campaign, three types of red sea bream food are presently offered, with prices ranging from 10,000 yen to 15,000 yen for single items and 30,000 yen (77 – 230 €) for a three-item assortment. In addition to red sea bream, Regional Fish Co. plans to develop and market new varieties of marine products such as fish and crustaceans improved by genome editing.

This is the second report of genome-edited foods in Japan, following tomatoes with increased GABA content after deleting a decarboxylase gene, developed and marketed by Sanatech Seed, a startup from the University of Tsukuba.

27-8 Grillus, a startup on edible crickets for human nutrition

Grillus is a startup from the University of Tokushima that produces edible crickets and sells cricket-derived as „circular food“. Basic technology consists of mass production of a highly uniform albino strain of the Dipterocarpus cricket, which has been maintained at the University of Tokushima for generations. The crickets are then dried and grinded providing a highly nutritious powder of about 70% protein and 20% fat. Flavor comes from the aroma produced during the drying process. Presently, the company offers 3 products:

  1. “cricket ramen” made from crickets at a ramen restaurant in Tokyo
  2. “cricket miso ramen” made from crickets and miso at a ramen restaurant in Tokushima Prefecture, and 
  3. “cricket rice crackers” with a shrimp-like flavor produced by MUJI Co.

The company is also considering to develop genome-edited crickets with improved taste, reduced allergens, strains that can be bred at high density, strains with a regulated metabolic system for functional components, and strains with higher nutritional value, e.g., increased content of specific amino acids.

26-8 Japanese consortium achieves solar hydrogen production on 100 m2 scale

A consortium of ARPChem, Fujifilm, TOTO, Mitsubishi Chemicals and the University of Tokyo, supported by NEDO, has installed and operated, since August 2019, a demonstrator for photocatalytic water splitting and succeeded in separating and recovering high-purity „solar hydrogen“ from the mixture of hydrogen and oxygen generated by water decomposition. The system consists of a photocatalytic panel reactor  connected so that it has a light-receiving area of 100m2 and a gas separation module with a built-in separation membrane. The top of this reactor is made of transparent glass and a strontium titanate photocatalyst sheet. There is a small gap of 0.1 mm between the photocatalyst sheet and the glass through which water is supplied for the reaction. The strontium titanate photocatalyst uses sunlight UV for water splitting, with a quantum yield of almost 100%. It is manufactured by spraying photocatalyst onto the substrate. The gas separation module can maintain stable gas separation by properly controlling the gas flow rate regardless of sunlight conditions, and was operated outdoors for 65 days without losing its functionality. In addition, due to the proper design of the photocatalytic reaction system, there was no spontaneous ignition or explosion during the outdoor test. In a separate project, catalysts and process technologies are being developed to synthesize C2 to C4 olefins from hydrogen produced from this module and carbon dioxide emitted from power plants and factories.
