Abstract
Several strains of Micrococcus have been isolated by enrichment with one of several phthalate esters as sole carbon source. They have been separated into four groups by their esterase content and nutritional characteristics. The catabolic potential for phthalate utilization found in these strains provides further support for designation of the four groups. Pathways for phthalate utilization by 4,5-dihydroxyphthalate and/or 3,4-dihydroxyphthalate and protocatechuate and/or 2,3-dihydroxybenzoate are outlined, which suggests that micrococci possess substantial potential for the catabolism of aromatic compounds.
