The integral image is typically used for fast integrating a function over a rectangular region in an image. We propose a method that extends the integral image to do fast integration over the interior of any polygon that is not necessarily rectilinear. The integration time of the method is fast, independent of the image resolution, and only linear to the(More)
A second sipS2(BA) gene was PCR cloned from Bacillus amyloliquefaciens. The deduced aa sequence is similar to those of the SPases of B. subtilis, B. amyloliquefaciens, and B. licheniformis and the domain structure of the gene has been preserved. A low level of monocistronic gene transcription could be shown using Northern analysis. The sipS2(BA) gene was(More)
A series of 33 single and mosaic hybrid alpha-amylases was constructed from the genes amyBA or amyLI, encoding the alpha-amylases from Bacillus amyloliquefaciens (AmyBA) and Bacillus licheniformis (AmyLI). The hybrid proteins, consisting of the entire alpha-amylase sequence with a variable portion of AmyBA or AmyLI origin, were characterized in order to(More)
A small (19.8 kDa) protein was identified in Bacillus amyloliquefaciens ALKO 2718 cultures during growth in the presence of yeast extract and chitin, but not with glucose. The protein targets beta-chitin best, then alpha-chitin, but barely any other polysaccharide. This described chitin-binding protein (ChbB) is the first of its type from a Bacillus strain(More)
We isolated the gene amyE(TV1) from Thermoactinomyces vulgaris 94-2A encoding a nonglucogenic alpha-amylase (AmyTV1). A chromosomal DNA fragment of 2,247 bp contained an open reading frame of 483 codons, which was expressed in Escherichia coli and Bacillus subtilis. The deduced amino acid sequence of the AmyTV1 protein was confirmed by sequencing of several(More)
