The present invention relates to a process for reducing and/or preventing an increase in lactic acid levels in a fermentation product production process, such as especially ethanol production, wherein a lytic polysaccharide monooxygenase (LPMO) or an enzyme composition comprising an LPMO is added before or during saccharification and/or fermentation, or before or during propagation, to reduce and/or prevent an increase in lactic acid levels.

Processes for reducing lactic acid in a biofuel fermentation system and processes for producing a fermentation product

Processes for producing a fermentation product

Described herein arestrains MBG5038 and MBG5012 deposited under the Budapest Treaty and having accession Nos. NRRL Y67549 and NRRL Y67700, respectively, or a derivatives of strains NRRL Y67549 or Y67700 which exhibit one or more properties or defining characteristics ofstrains MBG5038 or MBG5012. Also described are compositions comprising theyeast and naturally occurring and/or non-naturally occurring components, as well as are processes for producing ethanol from starch-containing material using the strains.

Yeast for ethanol production

The invention relates to processes of multi-stage hydrolysis where different enzyme compositions are added in at least two stages of hydrolysis. In a first stage, a first enzyme composition of one or more cellulolytic enzymes and at least one of an oxidoreductase and an AA9 polypeptide having cellulolytic enhancing activity is added, followed by a latter stage in which a second enzyme composition comprising one or more cellulases is added. Also provided are processes for obtaining hydrolysis products and fermentation products using processes of the invention.

Two-stage process for enzymatic hydrolysis of lignocellulosic biomass

The invention relates to methods of preconditioning pretreated cellulosic material in the presence of a combination of phenol oxidizing enzyme and glucoamylase. The invention also relates to processes of producing sugars and fermentation products including a preconditioning step. Finally the invention relates to a composition suitable for preconditioning.

Methods of preconditioning pretreated cellulosic material

The invention relates to processes of producing sugars and/or fermentation products from pretreated cellulosic material comprising the steps of: preconditioning pretreated cellulosic material; hydrolyzing using a cellulolytic enzyme preparation; and fermenting sugars with a microorganism; wherein a solid-liquid separation step, resulting in a solid fraction and a liquid fraction, is carried out: after preconditioning, but before hydrolysis; or after hydrolysis, but before fermentation; wherein phenol oxidizing enzyme and hemicellulase are present or added during preconditioning; after preconditioning, but before hydrolysis; or during hydrolysis.

Processes of treating cellulosic material

Described herein are improved methods of degrading or converting cellulosic material into fermentable sugars using dithionite. Also described are improved methods of fermentation in the presence of dithionite.
