Dyadic is focused on the discovery, development, manufacture and sale of enzyme and protein products and solutions for the bio-energy, industrial enzyme and biopharmaceutical industries.
The patent is the seventh US patent issued to Dyadic adding to its portfolio of 60 international patents and more than 40 pending patent applications worldwide which cover various features of Dyadic’s proprietary technologies.
The invention embodied by this patent is a novel beta-glucosidase gene and its corresponding enzyme which when used in combination with other enzymes converts lignocellulosic containing biomass into glucose.
The patented beta-glucosidase gene and the corresponding enzyme was isolated from Dyadic’s patented and proprietary C1 fungus and was also identified through the genome annotation project conducted in conjunction with Scripps Florida.
Dyadic president and CEO Mark Emalfarb said the patent continues the company’s mission of both developing and protecting the technology necessary to produce low cost fermentable sugars from biomass for the manufacturing of many types of renewable fuels, specialty chemicals and other bio-based materials as an alternative to petroleum-based products.
"The beta-glucosidase gene covered by this patent has already been incorporated into several advanced C1 biofuel strains resulting in the production of higher levels of glucose which is helping Dyadic and its licensees lower the costs of producing these fuels, chemicals and other biomaterials," Emalfarb said.
