Santos AA, Kretzer LG, Dourado EDR, Rosa CA, Stambuk BU, Alves SL. Expression of a periplasmic β-glucosidase from Yarrowia lipolytica allows efficient cellobiose-xylose co-fermentation by industrial xylose-fermenting Saccharomyces cerevisiae strains. Braz J Microbiol 2025; 56:91-104.

Abstract
This study aimed to compare the effects of cellobiose hydrolysis, whether occurring inside or outside the cell, on the ability of Saccharomyces cerevisiae strains to ferment this sugar and then apply the most effective strategy to industrial S. cerevisiae strains. Firstly, two recombinant laboratory S. cerevisiae strains were engineered: CEN.PK-X-Bgl1YL, expressing the periplasmic β-glucosidase BGL1 from Yarrowia lipolytica; and CEN.PK-X-B7-T2, co-expressing the intracellular β-glucosidase SpBGL7 from Spathaspora passalidarum and the cellobiose transporter MgCBT2 from Meyerozyma guilliermondii. Both engineered strains were able to grown in media with cellobiose and to ferment this disaccharide. However, CEN.PK-X-Bgl1YL, which hydrolyzes cellobiose extracellularly, exhibited faster growth and superior batch fermentation performance. Furthermore, enzymatic and transport activities revealed that sugar uptake was possibly the limiting factor in cellobiose fermentation by CEN.PK-X-B7-T2. Since extracellular hydrolysis with the periplasmic β-glucosidase was more efficient for cellobiose fermentation, we integrated the BGL1 gene into two industrial xylose-fermenting S. cerevisiae strains. The resulting strains (MP-C5H1-Bgl1YL and MP-P5-Bgl1YL) efficiently co-consumed ∼ 22 g L- 1 of cellobiose and ∼ 22 g L- 1 of xylose in 24 h, achieving high ethanol production levels (∼ 17 g L- 1 titer, ∼ 0.50 g L- 1 h- 1 volumetric productivity, and 0.40 g g- 1 ethanol yield). Our findings suggest that the expression of periplasmic β-glucosidases in S. cerevisiae could be an effective strategy to overcome the disaccharide transport problem, thus enabling efficient cellobiose fermentation or even cellobiose-xylose co-fermentation.

Abstract
The use of plant biomass for biofuel production will require efficient utilization of the sugars in lignocellulose, primarily cellobiose, because it is the major soluble by-product of cellulose and acts as a strong inhibitor, especially for cellobiohydrolase, which plays a key role in cellulose hydrolysis. Commonly used ethanologenic yeast Saccharomyces cerevisiae is unable to utilize cellobiose; accordingly, genetic engineering efforts have been made to transfer β-glucosidase genes enabling cellobiose utilization. Nonetheless, laboratory yeast strains have been employed for most of this research, and such strains may be difficult to use in industrial processes because of their generally weaker resistance to stressors and worse fermenting abilities. The purpose of this study was to engineer industrial yeast strains to ferment cellobiose after stable integration of tabgl1 gene that encodes a β-glucosidase from Thermoascus aurantiacus (TaBgl1). The recombinant S. cerevisiae strains obtained in this study secrete TaBgl1, which can hydrolyze cellobiose and produce ethanol. This study clearly indicates that the extent of glycosylation of secreted TaBgl1 depends from the yeast strains used and is greatly influenced by carbon sources (cellobiose or glucose). The recombinant yeast strains showed high osmotolerance and resistance to various concentrations of ethanol and furfural and to high temperatures. Therefore, these yeast strains are suitable for ethanol production processes with saccharified lignocellulose.

Abstract
The β-glucosidases from Saccharomycopsis fibuligera (SfBGL1) and Trichoderma reesei (TrBGL1) were cloned and expressed in Pichia pastoris. Methanol concentration and pH significantly affected the production. The combined effects of the two factors were optimized by using the response surface method, resulting in a 137% and 84% increase in rTrBGL1 and rSfBGL1 yield compared to single-factor experiment. Structure and biochemical properties of the two enzyme were investigated and compared. They belong to glycosyl hydrolase family 3 and exhibit significant hydrolysis activity and low-level transglycosylation activity. The two enzymes show similar substrate affinity and ion-tolerance, and both of them can be activated by Cr(6+), Mn(2+) and Fe(2+). The rSfBGL1 has greater catalytic speed, higher specific activity and acid-tolerance than rTrBGL1, but rTrBGL1 is more thermostable and has higher optimal temperature than rSfBGL1. This study provides a useful and quick optimal method for recombinant enzyme production and makes a valuable comparison of biochemical properties, which opens important avenues of exploration for relationship between structure and function and further practical applications.
