18. A process for producing a carboxylic acid ester which comprises reacting a lankacidin antibiotic having a hydroxy group at the 14-position or a maridomycin antibiotic having a hydroxy group at the 9-position with a carboxylic anhydride to esterify said hydroxy group in the presence of carboxylesterase originating from Streptomyces rochei var. volubilis.

19. A process for producing a carboxylic acid ester which comprises reacting a primary or secondary C2-4 alcohol, a lankacidin antibiotic having a hydroxy group at the 14-position or a maridomycin antibiotic having a hydroxy at the 9-position, with a carboxylic anhydride to esterify said hydroxy group, in the presence of carboxylesterase originating from Streptomyces rochei var. volubilis, in an organic solvent.
