Title: Method of Directing Biosynthesis of Specific Polyketides
Inventor: KATZ LEONARD
IPC: C12N1/21
Filed: 1992-01-17
Abstract: A method to produce novel polyketide structures by designing and introducing specified changes in the DNA governing the synthesis of the polyketide is disclosed. The biosynthesis of specific polyketide analogs is accomplished by genetic manipulation of a polyketide-producing microorganism by isolating a polyketide biosynthetic gene-containing DNA sequence, identifying enzymatic activities associated within the DNA sequence, introducing one or more specified changes into the DNA sequence which codes for one of the enzymatic activities which results in an altered DNA sequence, introducing the altered DNA sequence into the polyketide-producing microorganism to replace the original sequence, growing a culture of the altered microorganism under conditions suitable for the formation of the specific polyketide analog, and isolating the specific polyketide analog from the culture. The method is most useful when the segment of the chromosome modified is involved in an enzymatic activity associated with polyketide biosynthesis, particularly for manipulating polyketide synthase genes from Saccarharopolyspora or Streptomyces.

Abstract: Magnetostrictive powder composite and method for the manufacturing of the magnetostrictive powder composite. The powder composite according to the invention is preferably used as a magnetostrictive element in sound projectors and vibration generators, transducers, actuators and in linear motors. The powder composite consists of magnetostrictive powder grains with chemical composition (RE)xT1-x, where RE represents one or a mixture of several rare earth metals, T represents Fe, Ni, Co or Mn or a mixture of these metals and x represents atomic fraction assuming a value between 0 and 1, whereby the grains are held together by a binder. The powder composite is formed in such a way that it exhibits a homogeneous magnetic flux, has a good strength and can be made with a built-in precompression. It can be equipped with coolant channels and/or with coil loops. The powder composite is produced by pressing together the magnetostrictive powder grains and the binder in order to plastically deform the grains, either completely or partially, which causes the magnetic domains in the grains to align perpendicularly to the applied compression pressure. In an alternative mode of execution according to the invention isostatic pressing is used.
