PRODUCTION OF ERYTHRITOL

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing erythritol by using a strain excellent in thermostability and erythritol productivity, substantially not forming a foam in culture in producing erythritol. SOLUTION: A new variant Aureobasidium sp. SN-γ96 strain (FERM BP-1431) capable of maintaining excellent growth and high erythritol productivity in an environment (medium) having >=40% (W/V) saccharide concentration, comprising a hydrophilic or noncohesive body cell (microbial cell) and not substantially forming a foam when aerobically cultivated in a liquid medium is inoculated into a medium comprising a saccharide as a carbon source and aerobically cultured. Erythritol is formed and accumulated in the culture solution and collected.
