MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202521121754 A) filed by Indian Institute Of Science Education And Research, Bhopal, Madhya Pradesh, on Dec. 4, 2025, for 'histone mutated yeast strain for delayed flocculation.'
Inventor(s) include Raghuvir Singh Tomar; and Ranu Singh.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a mutant yeast strain which shows delayed onset of flocculation without compromising the strain health or product quality. The mutant yeast strain comprises truncation of 11 amino acids from the N-terminus region of histone H3 from amino acid residue 25 to residue 36 and active FLO genes, shows delay in onset of flocculation but endpoint flocculation is as efficient as the respective wild-type strain. Delayed flocculation allows the strain to digest more wort during the fermentation process which enhances the product's shelf life, yield, and better flavor. Efficient end-point flocculation helps in efficient culture clearance, enhances re-pitching efficiency and is more cost-effective as it reduces the distillation and cooling cost of the brewery."
