Abstract

Large differences in colony forming capacity, ethanol production and inhibitor conversion were noted between nine different strains of Saccharomyces cerevisiae in anaerobic batch and fed-batch cultures on dilute acid wood hydrolysate. S. cerevisiae ATCC 96581 was able to metabolize all added glucose and mannose in fed-batch experiments. The choice of production strain will have a significant effect on the performance of a hydrolysate-based ethanol production plant.

    In this rMBR fermentation condition, benefitting from an initial furfural to cell ratio of 0.93:1, a complete furfural bioconversion was achieved within 40 h of fermentation. Although these concentrations of lignocellulosic degradation products have been reported to considerably disturb the fermentation [11,12], such effects were not observed in this rMBR set-up. According to the hypothetical scenarios presented previously [24], this represents sub-inhibitory conditions in which the cells’ physiological and metabolic state are not severely affected as the low diffusion rate of furfural only affects a fraction of cells located in the surface of the cell aggregate, while cells placed in the deeper layers continue to thrive on the nutrients provided in a sub-inhibitory microenvironment.

    These strains while often poly- or aneuploid, offer a greater genetic landscape to potentially deal with the inhibitors found in lignocellulosic hydrolysates. Environmental strains appear to be more robust as strains were found to be more tolerant to the inhibitors found in spruce (Brandberg et al., 2004) and wheat straw hydrolysates (Panagiotou and Olsson, 2007) relative to laboratory strains. The apparent potential of environmental strains for greater tolerance to inhibitors has led to surveys of strains from various environments to find strains with improved tolerance relative to strains currently in use at biofuel production facilities (Choudhary et al., 2017; Favaro et al., 2013; Field et al., 2015; Jin et al., 2013; Pereira et al., 2014).

  • Industrial robust yeast isolates with great potential for fermentation of lignocellulosic biomass

    2014, Bioresource Technology
    Citation Excerpt :

    As general trend, strains isolated from Brazilian ethanol plant and “cachaça” fermentations showed higher detoxification percentage of furans and ethanol production than the laboratory background strains and K. marxianus yeasts. Brandberg et al. (2004) reported an efficient conversion of HMF by isolated strain from spent sulphite liquor from Swedish pulp plant (ATCC 96581). In this case, the authors proposed that the same enzymes were involved in both process (ethanol production and furan conversion).
