A bacterial soil isolate designated 326-32B produces a new member of the monobactam series of antibiotics, MM 42842, and the bulgecins. Identification studies show isolate 326-32B to be a strain of Pseudomonas cocoveneans which is a species previously noted for the production of toxoflavin. A description of P. cocovenenans does not appear to have been previously published and the identify of strain 326-32B was established by means of a direct comparison with the deposited organism P. cocovenenans NCIB 9450. The properties of strain 326-32B, and P. cocovenenans NCIB 9450 were compared with those of the monobactam and bulgecin producing organisms Pseudomonas acidophila ATCC 31363 and Pseudomonas mesoacidophila ATCC 31433. The four organisms were found to share certain properties, including the ability to grow at pH 4.0.
