Process for biological production of organic acids
 An improved biological conversion of a nitrile such as acrylonitrile or a cyanopyridine into the corresponding carboxylic acid such as acrylic acid or a nicotinic acid by the action upon the nitrile of a nitrilase enzyme, in which the improvement resides in the use as the source of the enzyme of a microorganism of Rhodococcus, such as Rh. rhodochrous J-1, FERM BP-1478, which is cultured in the presence of a lactam compound.
