General description

2,3-Butanediol (2,3-BDO) is used as precursor in the synthesis of cyclic carbonates and methyl ethyl ketone.

Application

  • CRISPR/Cas9 in Pichia pastoris: 2,3-Butanediol (BDO) is used in the construction of P. pastoris cell factories as a representative example to demonstrate the procedures for integrating multiple heterologous genes using the CRISPR-based multiplex genome integration toolkit (Gao et al., 2024).
  • Antifungal activity in sorghum: 2,3-butanediol, a metabolite of A. oryzae YRA3, can induce the production of root exudates which modulate the growth of the rhizospheric fungi and bacteria (Rashad et al., 2023).
