摘要:
The present invention provides methods and compositions comprising at least one neutral metalloprotease enzyme in the relative absence of serine protease enzyme contaminants. In some embodiments, the neutral metalloprotease finds use in cleaning and other applications. In some particularly preferred embodiments, the present invention provides methods and composi-tions comprising Bacillus strains engineered to be deficient in multiple serine proteases, and their use in production of recombinant neutral metalloprotease(s).
摘要:
The present invention provides methods and compositions comprising at least one neutral metalloprotease enzyme that has improved storage stability. In some embodiments, the neutral metalloprotease finds use in cleaning and other applications. In some particularly preferred embodiments, the present invention provides methods and compositions comprising neutral metalloprotease(s) obtained from Bacillus sp. In some more particularly preferred embodiments, the neutral metalloprotease is obtained from B. amyloliquefaciens. In still further preferred embodiments, the neutral metalloprotease is a variant of the B. amyloliquefaciens neutral metalloprotease. In yet additional embodiments, the neutral metalloprotease is a homolog of the B. amyloliquefaciens neutral metalloprotease. The present invention finds particular use in applications including, but not limited to cleaning, bleaching and disinfecting.
摘要:
Alpha-amylases from Bacillus subtilis (AmyE), variants thereof, nucleic acids encoding the same, and host cells comprising the nucleic acids are provided. Methods of using AmyE or variants thereof are disclosed, including liquefaction and/or saccharification of starch. Such methods may yield sugars useful for ethanol production or high fructose corn syrup production. In some cases, the amylases can be used at low pH, in the absence of calcium, and/or in the absence of a glucoamylase.

摘要:
The present invention provides methods and compositions comprising at least one neutral metalloprotease enzyme that has improved stability in the presence of a metal chelator. In some embodiments, the neutral metalloprotease finds use in cleaning and other applications comprising citrate. In some particularly preferred embodiments, the present invention provides methods and compositions comprising variant neutral metalloprotease(s) engineered to resist citrate-induced autolysis.
摘要:
An α-amylase from Bacillus subtilis (AmyE) produces significant amounts of glucose from various carbohydrate substrates, including vegetable starch, maltoheptaose, and maltotriose. Among other things, this advantageous property allows AmyE or variants thereof to be used in a saccharification reaction having a reduced or eliminated requirement for glucoamylase. The reduction or elimination of the glucoamylase requirement significantly improves the efficiency of the production of ethanol or high fructose corn syrup, for example.
