DANISCO US Inc. Modified Yeast Over-Expressing GDS1 for Ethanol Production
Summary
The USPTO granted patent US12606599B2 to DANISCO US Inc. on April 21, 2026, covering modified yeast strains that over-express the glycerol-deficient suppressor GDS1. The patented yeast produces increased ethanol and decreased acetate compared to parental cells, making it suitable for large-scale ethanol production from starch substrates where acetate is undesirable. The patent names Zhongqiang Chen, Min Qi, Luan Tao, and Quinn Qun Zhu as inventors and covers compositions and methods for industrial fermentation applications.
What changed
The USPTO granted patent US12606599B2 to DANISCO US Inc. on April 21, 2026, covering modified yeast strains that over-express the glycerol-deficient suppressor GDS1. The invention increases ethanol yield while reducing acetate byproduct compared to parental yeast strains.
Biofuel producers, fermentation companies, and industrial biotechnology firms should be aware of this intellectual property protection. DANISCO US Inc. now holds exclusive rights to this yeast modification technology for large-scale ethanol production from starch substrates, which could affect licensing negotiations and competitive positioning in the biofuel and industrial fermentation sectors.

Abstract
Described are compositions and methods relating to modified yeast that over-express the glycerol-deficient suppressor, GDS1. The yeast produces an increased amount of ethanol and a deceased amount of acetate compared to parental cells. Such yeast is particularly useful for large-scale ethanol production from starch substrates where acetate in an undesirable end product.
