Participation in Upcoming Event –October 2026

PtBio Inc. is pleased to announce its participation in the following event.

Data-Driven Breeding of Red Shiso (Digital Breeding)

Together with Mishima Foods and Hiroshima University, we sequenced approximately 99% of the red shiso genome (approx. 1.26 billion base pairs) at the chromosome level, determining genome sequence information for digital breeding.

Gene Therapy for Rare Eye Diseases

In partnership with VC Gene Therapy and Hiroshima University, we are advancing the application of our purely domestic genome editing tool "ZF-ND1" to gene therapy for intractable diseases such as retinitis pigmentosa.

Egg for all — eggs that everyone can eat

For people with egg allergies — research and development of allergy-reduced eggs in which ovomucoid, one of the major allergens, has been removed.

Turning Food Waste into a Valuable Resource

In collaboration with Yanmar Holdings and Hiroshima University, we use metagenomic analysis to advance the recycling of food waste and other unutilized organic matter, aiming to establish a resource-circular food production system.

Next-Generation Sewage Treatment Through Metagenomic Analysis

In partnership with the City of Higashi-Hiroshima, Kanadevia, and Hiroshima University, we use metagenomic analysis (Bio-DX) to visualize the microbiome inside sewage treatment facilities, improving operating efficiency and cutting electricity use and CO₂ emissions, with an eye toward rolling out the "Higashi-Hiroshima model" nationwide and globally.

Genomic Data Analysis Opens the Future of Aquaculture

Together with FOOD & LIFE COMPANIES, the operator of Sushiro, Marine Birth, and Hiroshima University, we are pursuing data-driven selective breeding through genomic analysis to develop superior yellowtail seedlings and other species and achieve sustainable aquaculture.

Carbon Recycling with Microalgae

With Tsuneishi Kamtecs, Phytolipid Technologies, and Leave a Nest, we began a demonstration project in October 2025 that grows microalgae outdoors on factory flue gas. PtBio analyzes genes to help develop strains that hold up in outdoor conditions.
