Prophylactic and therapeutic agents for the prevention and treatment of viral-induced tumors and, in particular, compositions derived from an Aspergillus fermentation extract, and the use thereof, either directly or to prepare a medicament, for the prevention and treatment of viral-induced tumors in mammals. Such tumors include papilloma-induced tumors. The composition is topically administered.

Compositions for the prevention and treatment of viral-induced tumors

Method for producing a therapeautic composition for

The invention relates to an acid stable levan sucrase derived from Bacillus licheniformis NRRL B-19862. The levan sucrase is produced by culturing Bacillus licheniformis NRRL B-19862 in a suitable nutrient medium but in the absence of sucrose. The invention also discloses compositions containing the levan sucrase.

Bacillus licheniformis NRRL B-18962 capable of producing levan sucrase

The present invention relates to an acid stable levan sucrase enzyme which is not induced by sucrose. The present invention relates to a process for the preparation of this enzyme and microorganisms producing the levan sucrase enzyme. The invention also provides compositions containing this enzyme.

Process for producing levan sucrase using Bacillus licheniformis

Disclosed is a method for causing the dissociation of microbial mycelium and extracellular lipase bound thereto and increasing the measurable activity of the lipase. The method involves treating an aqueous suspension of the mycelium with the anhydride of a dicarboxylic acid which results in dissociation of the mycelium and lipase thereby facilitating recovery of the lipase.
