Title: Xuewu Guo’s Innovations in Brewing Biotechnology.

Introduction

Xuewu Guo is an inventor based in Tianjin, China, whose work focuses on bioengineering and industrial microorganisms for brewing. His patent portfolio includes 3 patents, with inventions aimed at shaping beverage flavor and improving fermentation outcomes.

Latest Patents

One of Guo’s recent inventions concerns a genetically engineered strain for brewing. The strain heterologously overexpresses the genes ALD6, ACS1, and AeAT9. The disclosed approach is designed to increase ethyl acetate production while reducing higher alcohols, while retaining ethanol fermentation characteristics. The invention may support the flavor profile and quality of Chinese baijiu and contribute to improvements in fermentation processes.

Another invention describes a strain engineered for high ethyl butyrate production. It overexpresses the genes Erg10, Hbd, Crt, Ter, and AAT. The patent reports an ethyl butyrate yield of 77.33 ± 3.79 mg/L for the constructed strain. A strain with double-copy expression of Ter and AAT reached 99.65 ± 7.32 mg/L, a reported increase of 28.9% over the EST strain. The engineered strain also produced 40.93 ± 3.18 mg/L of ethyl crotonate.
