Abstract: Described herein are host cells comprising lactate dehydrogenase activity, lactaldehyde dehydrogenase activity, lactaldehyde reductase activity, propanediol dehydratase activity, and/or n-propanol dehydrogenase activity, wherein the cells are capable of producing n-propanol. Also described are methods of producing n-propanol comprising (a) cultivating the host cells having lactate dehydrogenase activity, lactaldehyde dehydrogenase activity, lactaldehyde reductase activity, propanediol dehydratase activity, and/or n-propanol dehydrogenase activity in a medium under suitable conditions to produce n-propanol; and (b) recovering the n-propanol. Methods of producing polypropylene from the recombinant n-propanol are also provided.

Abstract: A screening module 10 comprises a frame component 12 to be secured to an underlying screen deck, in use. A screening panel 14 is carried by the frame component 12. The screening panel 14 comprises an operatively upper screening surface 16 and a support structure 18 underlying the screening surface 16 with a plurality of spaced protrusions 20 being supported by and standing proud of the support structure 18. Operatively upper ends of the protrusions 20 lie substantially in a plane of the screening surface 16 and the protrusions 20 define a plurality of screening apertures 22 in the screening surface 16.

Abstract: A Bacillus licheniformis mutant host cell derived from a parent B. licheniformis host cell, which mutant host cell is mutated in one or more gene(s) encoding one or more polypeptide(s) involved in sporulation which is at least 80% identical to one or more of the polypeptides shown in SEQ ID NO's: 2 to 191, wherein the mutant host cell expresses at least 5% less of the one or more polypeptide(s) involved in sporulation than the parent host cell, when they are cultivated under comparable conditions.

Abstract: A Bacillus licheniformis mutant host cell derived from a parent B. licheniformis host cell, which mutant host cell is mutated in one or more gene(s) encoding one or more polypeptide(s) involved in antibiotic synthesis which is at least 80% identical to one or more of the polypeptides shown in SEQ ID NO's: 2 to 22, wherein the mutant host cell expresses at least 5% less of the one or more polypeptide(s) involved in antibiotic synthesis than the parent host cell, when they are cultivated under comparable conditions.

Abstract: A Bacillus licheniformis mutant host cell derived from a parent B. licheniformis host cell, which mutant host cell is mutated in one or more gene(s) encoding one or more secreted polypeptide(s) which is at least 80% identical to one or more of the polypeptides shown in SEQ ID NO's: 2 to 248, wherein the mutant host cell secretes at least 5% less of the one or more secreted polypeptide(s) than the parent host cell, when they are cultivated under comparable conditions.

Abstract: A Bacillus licheniformis mutant host cell comprising a mutation (deletion) in one or more genes encoding polypeptides having proteolytic activity wherein the mutant host cell expresses at least 5% less of the one or more proteases than the parent host cell, when cultivated under comparable conditions. The mutant host cell is used for producing heterologous polypeptides.
