The present invention relates to a method of producing biofuel, more specifically a method of producing biofuel comprising the steps of generating monosugars from marine algae, or from polysaccharides extracted from marine algae by treating the marine algae or the polysaccharides with a hydrolytic enzyme and/or a hydrolytic catalyst; and fermenting the monosugars using a microorganism to produce biofuel. The method of producing biofuel of the present invention solve the problem of raw material suppliance since it uses marine algae as a raw material for biomass, and reduce the production costs by excluding lignin eliminating process that has been required by the conventional method using wood-based raw materials, resulting in economic and environmental advantages.

The present invention is directed to a pharmaceutical compositions improving percutaneous absorbability by absorption assistants, which remarkably increase permeation and dissolution of piroxicam, and penetration enhancers. A further surprising feature of the present invention resides in the fact that absorption assistant which assists penetration enhancer is able to include the active substance excessively in adhesive matrix as solvent of the active substance.

An Escherichia coli (ATCC 68319) containing a gene encoding a novel maltogenic amylase of Bacillus licheniformis (BLMA), wherein said gene has a length of about 3.5 kb; said gene expresses a gene product capable of hydrolyzing cyclodextrin, pullulan, as well as starch at an optimum temperature of about 50.degree. C. at a pH of about 7; said gene product has sugar transferase activity in the presence of glucose; and said Escherichia coli produces said gene product optimally when grown in Luria broth, for 24 hours, at 37.degree. C.
