Abstract: A new expression system is provided which comprises component(s) of a lipase regulation cascade. the lipase regulation cascade as disclosed herein includes a kinase, a DNA binding regulator, a polymerase, a promoter, an upstream activating sequence, and secretion factors. Plasmids and transformed cells are also provided as well as methods of transforming host cells using the plasmids. Further, there is provided a kinase that can regulate the expression of a protein, a DNA binding regulator that can regulate the expression of a protein, a Pseudomonas alcaligenes polymerase, a Pseudomonas alcaligenes sigma 54 promoter, a Pseudomonas alcaligenes upstream activating sequence, the Pseudomonas alcaligenes secretion factors XcpP, XcpQ, XcpR, XcpS, XcpT, XcpU, XcpV, XcpW, XcpX, XcpY, XcpZ and the xcp regulators OrfV, OrfX.
Abstract: A multi-layer enzyme granule for use in liquid detergents and cleaners is produced, comprising a seed or carrier particle; an outer coating; and, between the particle and the coating layer, a low-density filler and an enzyme, wherein the granule has a density of less than 1.4 g/cm3. Also disclosed are methods for making such enzyme-containing granules including using fluidized bed technology.
Abstract: A novel cellulase composition is provided which is predicable by an Actinomycete. The cellulase has an approximate calculated molecular weight of 36 kD and has a pH optimum at 40° C. of 8 and at 60° C. of 7. Also provided is a DNA encoding said cellulase, a method for producing the cellulase and applications thereof.
