Batch Cultures

The ethanolic fermentation in batch cultures of Pachysolen tannophilus was studied experimentally varying the initial concentrations of two of the components in the culture medium: glucose between 0 and 200 g l-1 and yeast extract between 0 and 8 g l-1. The yeast extract appears to be a significant component both in cell growth and for ethanol production.

Abstract Background Mucor hiemalis is a dimorphic fungus that efficiently produces ethanol from different sugars; however, the yield of ethanol production highly depends on the fermentation conditions. Objective The conditions for obtaining a high ethanol production yield were optimized in this study. Materials and methods A response surface methodology was used to optimize pH, temperature, and time of ethanolic fermentation by M. hiemalis. Additionally, wheat flour was enzymatically hydrolyzed and the hydrolysate solution with high glucose concentration was fermented by the fungus. Results The optimum pH, temperature, and time were 5.5, 30°C, and 36 h, respectively. Maximum ethanol and glycerol yields were 0.48 and 0.06 g/g, respectively. The biomass yield was between 0.01 and 0.16 g/g of consumed glucose. The results showed that the fungus was able to produce ethanol in a medium containing 5.5% (v/v) ethanol, while higher ethanol concentration prevented further production of ethanol. Conclusion At the optimized conditions, the fungus was able to consume glucose with the concentration of 140 g/L and produce ethanol with a yield of 0.45 g/g, which was comparable to that by Saccharomyces cerevisiae.

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.
