- Escherichia coli strain DH5 ⁇ (Life Technologies, Rockville, MD, USA) was used for cloning. Plasmids and yeast strains are summarized in Table 1. E. coli was grown in LB-medium (Sambrook et al., 1989) with lOOmg/l ampicillin. Liquid cultures of S. cerevisiae defined mineral medium (Verduyn et al., 1990), supplemented with glucose, xylose or arabinose as carbon source and in necessary, buffered with phthalate (10.21 g/l phthalate, 2.1 g/l KOH, pH 5.5) before sterilization. For plate cultures YPD-agar or SC-plates (6.7 g/l Difco Yeast Nitrogen Base, 30 g/l agar) were used. Geneticin was added to YPD plates at 200 mg/l.
- a single-copy integrative vector carrying a mutant L-ribulokinase from E. coli (Becker and Boles, 2003 Appl Environ Microbiol 69, 4144-50) was constructed for attaining a low-level expression of the gene.
- the KanMX antibiotic marker flanked by lox-sequences was amplified from pUG6 (Guldener et al. 1996) with primers containing the ApaJ restriction site, and the resulting fragment digested with Apal was cloned to plasmid YEparaB (Becker and Boles, 2003 Appl Environ Microbiol 69, 4144-50), also cut with Apal.
- the resulting plasmid was cut with SnaBI and Eco 311 to destroy the 2 ⁇ -sequence of the plasmid.
- the resulting plasmid YIpAraB Figure 1.
- the resulting plasmid pAraBint Figure 1. was digested with Eco ⁇ ll located in the Trpl-marker of the plasmid and transformed in S. cerevisiae TMB 3400, resulting in integration of the plasmid in the Trpl-locus. Transformants were selected on YPD-plates containing geneticin, and the presence of the AraB gene was confirmed by PCR.
- the resulting yeast strain was named TMB 3060.
- plasmid containing two adjacent regions from the S. cerevisiae ribosomal DNA (rDNA) in an ends-in fashion was constructed.
- Two PCR-products were amplified from S. cerevisiae CEN.
- PK 113-5D chromosomal DNA with primers containing restriction sites for Kpnl and Apal or Sad and SacII.
- the 400 - 500 bp- long PCR products were digested with these restriction enzymes and cloned into pBluescript SK cut with the same enzymes.
- the resulting plasmid was named prDNA2 ( Figure 2.).
- strain JBY25 (Becker and Boles, 2003) by progressively integrating PCR-amplified arabinose utilization genes/loxP-kanMX-loxP cassettes into its rDNA locus.
- an araD/loxP-kanM-loxP cassette containing short flanking homologous rDNA sequences was transformed into strain JBY25 selecting for growth with 2% glucose in the presence of the antibiotic G418.
- YEparaA, YEpara ⁇ G361A and YEpGAL2 (Becker and Boles, 2003) were transformed. Transformants growing on L-arabinose as the sole carbon source were cured for their plasmids and the kanMX marker.
- Xylose and arabinose consumption rates and product yields from anaerobic batch fermentations by strains BWY2, TMB 3400 and TMB 3063.
- Mineral medium with mixtures of 20 g/l glucose and 20 g/l xylose or 20 g/l glucose and 20 g/l arabinose as well as 20 g/l glucose, 20 g/l xylose and 20 g/l arabinose were used as indicated.
- Product yields are calculated from the pentose phase of the fermentation.
- TMB 3063 0.042 ⁇ 0.002 0.029 ⁇ 0.002 0.68 ⁇ 0.17 0.11 ⁇ 0.03 0.03 ⁇ 0.00 0.06 ⁇ 0.01 0.16 ⁇ 0.03 0.32 ⁇ 0.06 ⁇ 0.02 14.7 ⁇ 2.0
- Strain JBY25-4M (Becker and Boles, 2003) was selected for improved arabinose fermentation on a medium with 2% arabinose under oxygen-limited conditions over a period of 17 weeks. For this, cells were grown semi-anaerobically in liquid medium with L- arabinose as the sole carbon source for up to 5 days, and progressively diluted into fresh medium whenever the cells had reached the stationary phase. This finally resulted in strain BWY1-4M that shows an increased growth rate on arabinose medium, higher biomass yields and improved arabinose fermentation.
- the integrative vector YIpXR/XDH/XK (Eliasson et al., 2000) harbouring P. stipitis XYLl and XYLZ genes, and S. cerevisiae XKSl and with HIS3 as selectable marker was linearized with Pstl to target integration into the HIS3 locus in the genome of strain BWYl.
- the transformants were selected for growth on a medium without histidine and with 2% glucose as carbon source. After replica plating the transformants were shown to be able to grow on a synthetic medium with 2% xylose as the sole carbon source.
- the araA gene from B. subtilis together with the HXT7 promoter and the CYCl terminator was recloned from plasmid YEparaA (Becker and Boles, 2003) onto plasmid p426H7 with URA3 as the selectable marker, resulting in plasmid YEparaA (URA3).
- Plasmids YEparaA (URA3), YEparaS G361A , YEparaD (Becker and Boles, 2003) were transformed into strain BWYl with YIpXR/XDH/XK integrated into its genome, selecting for growth on synthetic minimal medium with 2% glucose. After replica plating the transformants were able to grow on media with xylose and/or arabinose as the sole carbon source(s), and to produce ethanol from both of them.
- Figure 6 shows the optical density obtained when fermenting a modified TMB 3061 strain comprising one or more copies of araA and/or araD.
- the strain was fermented in a 50 ml medium containing xx /I of xylose and 50 g/l of arabinose.
- the OD was determined at 620 nm and reflects the formation of ethanol during simultaneous consumption of arabinose and xylose.
- TMB 3061 was re-transformed with the AraA gene. Transformants with improved arabinose growth were selected in liquid YNB medium containing 20 g/l arabinose. After three rounds of sequential transfer to new liquid cultures, aliquots were plated on arabinose plates and single colonies were purified and analysed for arabinose growth. The best clone was named TMB 3063.
- the improved strain TMB 3063 grew on 50 g/l arabinose with the growth rate of 0.04 h "1 and the growth continued until OD 62 o of about 6 ( Figure 7).
