Abstract

"PROCESSO PARA A REMOçãO DE MONÈMERO DE AMIDA INDESEJáVEL DE UMA PREPARAçãO DE POLIAMIDA". A invenção presente apresenta um processo para a remoção de um composto de monómero de amida indesejável de uma poliamida ou preparação de amida polimerizada em um pH de cerca de 2 a menos do que 6, por conversão do composto do monómero de amida no composto ácido correspondente utilizando-se uma cultura pura de uma família de microorganismos induzidos capazes de converter um radical amida em um radical ácido.
