Is Pichia stipitis homothallic?
Is Pichia stipitis homothallic?
Pichia stipitis has been shown to be haplotonic and homothallic [11] and goes through ascomycetous sexual reproduction [5]. Pichia stipitis is known for its ability to produce ethanol by fermenting xylose [19]. Xylose enters the cell through a proton symport transporter [16].
Can Pichia stipitis ferment xylose to produce ethanol?
The yeast Pichia stipitis NRRL Y-7124 has the ability to ferment xylose to 76% of theoretical ethanol yield. Lignocellulose hydrolyzates containing xylose and glucose provided good substrates for ethanol production by Pachysolen tannophilus NRRL Y-2460 and S. cerevisiae NRRL Y-2235.
What is the size of a single P stipitis?
As with most members of the Saccharomycetales order a single P. stipitis individual has a size of 3 to 5 µm in diameter. Budding from asexual reproduction may cause deviation from the usual spherical or ellipsoidal shape of an individual.
What is Scheffersomyces stipitis?
Scheffersomyces ( Pichia) stipitis is an ascomycetous yeast that has been extensively investigated for the fermentation of xylose to ethanol, L-lactic acid and other products from hemicellulose, the second abundant component of cellulosic biomass (Hahn-Hägerdal et al. 2007, Ilmén et al. 2007, Jeffries 2006 ).
