Concerns about fossil fuel depletion and the environmental effects of greenhouse gas
emissions have led to widespread fermentation-based production of bioethanol from corn …

Humans rely on the ability of budding yeasts to grow without oxygen in industrial scale
fermentations that produce beverages, foods, and biofuels. Oxygen is deeply woven into the …

Background Developing novel microbial cell factories requires careful testing of candidates
under industrially relevant conditions. However, this frequently occurs late during the strain …

In the production of fuel ethanol from sugarcane in Brazilian biorefineries, one way to
achieve lower production costs is the fermentation of sugars into ethanol at high …

Current large-scale, anaerobic industrial processes for ethanol production from renewable
carbohydrates predominantly rely on the mesophilic yeast Saccharomyces cerevisiae. Use …

Both the identity and the amount of a carbon source present in laboratory or industrial
cultivation media have major impacts on the growth and physiology of a microbial species …

In Saccharomyces cerevisiae, acyl-coenzyme A desaturation by Ole1 requires molecular
oxygen. Tween 80, a poly-ethoxylated sorbitan-oleate ester, is therefore routinely included …

All known facultatively fermentative yeasts require molecular oxygen for growth. Only in a
small number of yeast species, these requirements can be circumvented by …

Biosynthesis of sterols, which are considered essential components of virtually all eukaryotic
membranes, requires molecular oxygen. Anaerobic growth of the yeast Saccharomyces …

Neocallimastigomycetes are unique examples of strictly anaerobic eukaryotes. This study
investigates how these anaerobic fungi bypass reactions involved in synthesis of pyridine …
