✦ Synopsis

26-Deoxylaidlomycin (I, C,,H,,O, ,Na) was isolated together with its cometabolite laidlomycin (11) from the mycelium of Streptoverticillium olivoreticuli IMET 43782. Its structure was determined by high-field I3C and 'H NMR. and MS spectral studies. The antibacterial activity of I against Burillus subtilis ATCC 6633 was found to be approx. four times higher than that of laidlomycin (11). 37 36 35 M e C H2C 0 0 Me 3L U. CRAW et al.
