Salt Tolerant

Algae are referred to as a third-generation biomass for ethanol production. However, salinity treatment is a problem that needs to be solved, because algal hydrolysates often contain high salt. Here, we isolated the salt-tolerant ethanol-producing yeast Citeromyces matritensis M37 from the east coast of Miura Peninsula in Japan. This yeast grew under osmotic stress conditions (20% NaCl or 60% glucose). It produced 6.55 g/L ethanol from YPD medium containing 15% NaCl after 48 h, and the ethanol accumulation was observed even at 20% NaCl. Using salted Undaria pinnatifida (wakame), we obtained 6.33 g/L glucose from approx. 150 g/L of the salted wakame powder with acidic and heat pretreatment followed by enzymatic saccharification, and the ethanol production reached 2.58 g/L for C. matritensis M37. The ethanol concentration was 1.4 times higher compared with that using the salt-tolerant ethanol-producing yeast Zygosaccharomyces rouxii S11.

Insight Into

The study explored changes in carbon fluxes in the central metabolism of brewer’s yeast in the absence of building blocks such as adenine or nitrogen. These flows provide insight into changes in the central metabolism of brewer’s yeast. It was found that in the absence of a building block, the yeast mainly uses fermentation for growth, producing ethanol. Deletion of Δade1 in purine de novo synthesis reduces ethanol production, and decreased glycerol production in adenine starvation indicates a slowing of central metabolism.
