摘要:
The present invention disclosed novel recombinant DNA cloning vectors including pMND1000 and vectors derived therefrom for use in Streptomyces and related organisms. These novel cloning vectors contain genetic markers that provide antibiotic resistance or colorimetric selectivity to the host cells. The invention further comprises transformants of the aforementioned vectors.
摘要:
New A83543 components, including fermentation products A83543K, A83543O, A83543P, A83543U, A83543V, A83543W and A83543Y and N-demethyl derivatives, and salts thereof, are useful for the control of insects and mites. The pseudoaglycones of the new A83543 components are useful for the preparation of A83543 components. Methods are provided for making the new A83543 components by culturing of Saccharopolyspora spinosa NRRL 18395, NRRL 18537, NRRL 18538, or NRRL 18539, or NRRL 18743 or NRRL 18719 or NRRL 18823 in suitable culture medium. Insecticidal and ectoparasiticidal compositions containing new A83543 components are also provided.
摘要:
New glycopeptide antibiotic A82846, comprising A82846A, A82846B and A82846C, is produced by Nocardia orientalis strains NRRL 18098, NRRL 18099 and NRRL 18100. The A82846 antibiotics have activity against Gram-positive bacteria comparable to that of vancomycin.
