In current years, so-called `non-conventional’ yeasts have gained considerable interest for various factors. Very first, S. cerevisiae is actually a Crabtree good yeast that covers the majority of its ATP requirement from Sulfinpyrazone Inhibitor substrate-level phosphorylation and fermentative metabolism. In contrast, most of the non-conventional yeasts, such as Yarrowia lipolytica, Kluyveromyces lactis or Pichia pastoris, have a respiratory metabolism, resulting in drastically higher biomass Correspondence: [email protected] 1 Institute of Molecular Biosciences, BioTechMed Graz, University of Graz, Humboldtstrasse 50II, 8010 Graz, Austria Full list of author details is obtainable in the end of your articleyields and no loss of carbon due to ethanol or acetate excretion. Second, S. cerevisiae is hugely specialized and evolutionary optimized for the uptake of glucose, but performs poorly on most other carbon sources. Various nonconventional yeasts, however, are in a position to develop at high growth prices on option carbon sources, like pentoses, C1 carbon sources or glycerol, which might be offered as cheap feedstock. Third, non-conventional yeasts are extensively exploited for production processes, for which the productivity of S. cerevisiae is rather low. Prominent examples are the use of P. pastoris for highlevel protein expression [2] and oleaginous yeasts for the production of single cell oils [3].

A single such tool would be the use of reconstructed metabolic networks for the computational analysis and optimization of pathways and production processes. These genomescale models (GSM) are becoming increasingly crucial as entire genome sequences and deduced pathways are out there for many distinct organisms. In mixture with mathematical algorithms like flux balance evaluation (FBA) and variants 2-Iminobiotin Protocol thereof, GSMs possess the possible to predict and guide metabolic engineering tactics and considerably improve their success prices [4].
