The antibiotic of Formula I is effective in inhibiting the growth of gram-negative and gram-positive bacteria. The compound of Formula I is prepared by cultivating a strain of Streptomyces species 372A in an aqueous carbohydrate solution containing a nitrogenous nutrient under submerged aerobic conditions until substantial activity versus gram-positive and gram-negative bacteria is imparted to said solution and then recovering said compound of Formula I from the solution.
