Patent
Butamax Advanced Biofuels LLC | Date: 2017-04-12

Dihydroxy-acid dehydratase (DHAD) variants that display increased DHAD activity are disclosed. Such enzymes can result in increased production of compounds from DHAD requiring biosynthetic pathways. Also disclosed are isolated nucleic acids encoding the DHAD variants, recombinant host cells comprising the isolated nucleic acid molecules, and methods of producing butanol.


Patent
Butamax Advanced Biofuels LLC | Date: 2017-01-16

Methods of screening for dihydroxy-acid dehydratase (DHAD) variants that display increased DHAD activity are disclosed, along with DHAD variants identified by these methods. Such enzymes can result in increased production of compounds from DHAD requiring biosynthetic pathways. Also disclosed are isolated nucleic acids encoding the DHAD variants, recombinant host cells comprising the isolated nucleic acid molecules, and methods of producing butanol.


Patent
Butamax Advanced Biofuels LLC | Date: 2016-12-12

The present invention is related to recombinant host cells comprising: (i) at least one deletion, mutation, and/or substitution in an endogenous gene encoding a polypeptide that converts pyruvate to acetaldehyde, acetyl-phosphate or acetyl-CoA; and (ii) a heterologous polynucleotide encoding a polypeptide having phosphoketolase activity. The present invention is also related to recombinant host cells further comprising (iii) a heterologous polynucleotide encoding a polypeptide having phosphotransacetylase activity.


Patent
Butamax Advanced Biofuels Llc | Date: 2016-10-14

The present invention relates to the fermentative production of alcohols including ethanol and butanol, and processes for improving alcohol fermentation employing in situ product removal methods.


Patent
Butamax Advanced Biofuels LLC | Date: 2016-10-18

Methods for the fermentative production of four carbon alcohols is provided. Specifically, butanol, preferably isobutanol is produced by the fermentative growth of a recombinant bacterium expressing an isobutanol biosynthetic pathway.


Patent
Butamax Advanced Biofuels LLC | Date: 2016-11-10

The invention relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed by extraction into a water immiscible organic extractant during the fermentation. The invention also relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed during the fermentation by extraction into a water-immiscible extractant composition. The invention further relates to compositions comprising a solution of butanol in a water immiscible organic extractant composition.


Patent
Butamax Advanced Biofuels LLC | Date: 2016-10-27

Polypeptides having ketol-acid reductoisomerase activity are provided. Also disclosed are recombinant host cells comprising isobutanol biosynthetic pathways employing such polypeptides. Methods for producing isobutanol employing host cells comprising the polypeptides having ketol-acid reductoisomerase activity are also disclosed.


Patent
Butamax Advanced Biofuels LLC | Date: 2016-11-01

The present invention is related to a recombinant host cell, in particular a yeast cell, comprising a dihydroxy-acid dehydratase polypeptide. The invention is also related to a recombinant host cell having increased specific activity of the dihydroxy-acid dehydratase polypeptide as a result of increased expression of the polypeptide, modulation of the FeS cluster biosynthesis of the cell, or a combination thereof. The present invention also includes methods of using the host cells, as well as, methods for identifying polypeptides that increase the flux in an FeS cluster biosynthesis pathway in a host cell.


Patent
Butamax Advanced Biofuels LLC | Date: 2017-06-21

The invention relates to the fields of industrial microbiology and alcohol production including production of yeast products with features suitable for transport, storage, and utilization in fermentation


Patent
Butamax Advanced Biofuels LLC | Date: 2017-02-15

The present disclosure is directed to methods, approaches, devices, equipment, and systems for minimizing or reducing contamination in facilities implementing fermentation or distillation processes. In embodiments, the facility is a biofuel plant that produces fermentation product such as product alcohol like butanol. In some embodiments, the methods, approaches, devices, equipment, and systems are operable to implement clean in place contamination (CIP) mitigation techniques that can also include sterilize in place (SIP) mitigation techniques to decontaminate equipment including surfaces of the equipment that come in contact with materials used in the production of product alcohols. Other cleaning and contamination minimizing techniques are also described.
