Transformation of Bacillus cereus vegetative cells by electroporation.
Transformation of untreated vegetative cells of Bacillus cereus 569 with plasmid pC194 (1.8 megadaltons) by high-voltage electroporation resulted in a maximum of 2 x 10(-5) transformants per viable cell. Transformation of a 130-megadalton plasmid occurred at a comparable frequency. The method was simple, rapid, and yielded transformant colonies in 14 to 24 h. Transformation was obtained with un...
متن کاملMICROBIAL TRANSFORMATION OF CHOLESTEROL BY MYCOBACTERIUM SMEGMATIS
Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...
متن کاملPrumycin produced by Bacillus cereus.
The isolation of prumycin from cultured broths of Streptomyces kagawaensis has been reported by HATA et al.') It inhibits the growth of some bacteria and fungi,') and shows antitumor action.') The structure determined by OMURA et al.3,4) to be 4-D-alanylamino-2-amino-2,4-dideoxy-Larabinose. We isolated this antibiotic from cultured broths of a strain BMG366-UF5 which was isolated from a soil sa...
متن کاملProduction of kanosamine by Bacillus cereus UW85.
Bacillus cereus UW85 produces two antibiotics that contribute to its ability to suppress certain plant diseases (L. Silo-Suh, B. Lethbridge, S. J. Raffel, H. He, J. Clardy, and J. Handelsman, Appl. Environ. Microbiol. 60:2023-2030, 1994). To enhance the understanding of disease suppression by UW85, we determined the chemical structure, regulation, and the target range of one of the antibiotics....
متن کاملAntimicrobial Effects of Honey on Bacillus Cereus
Abstract Background and Objective: Honey is a healthy and nutritious food that has been used for a long time as a treatment for different diseases. One of the applied properties of honey is its antimicrobial effect, which differs between different types of honey due to variation of phenolic and antioxidant compositions. This study aimed to assess antimicrobial effect of honey on Bacillus cereu...
