Abstract

New monobactams, PB-5266 A, B and C were isolated from the culture filtrate of Cytophaga johnsonae PB-5266 by various types of column chromatography and preparative reversephase HPLC. PB-5266 A, B and C exhibited weak antibacterial activity against a sensitive mutant of Escherichia coli to β-lactam antibiotics.
