Abstract

"MéTODO PARA PRODUZIR áCIDO SUCCìNICO". Produz-se o ácido succínico permitindo que uma bactéria modificada para intensificar -a atividade da fumarato reductase, ou uma preparação celular da mesma reaja com uma matéria prima orgânica em uma solução de reação contendo um entre um íon carbonato, um íon bicarbonato e gás dióxido de carbono para gerar ácido, succínico. Mais preferivelmente, o ácido succínico é produzido permitindo-se que uma bactéria modificada para intensificar as atividades da fumarato reductase e da piruvato carboxilase e reduzir a atividade da lactato deidrogenase, ou uma preparação celular da mesma, reaja com uma matéria prima orgânica em uma solução de reação contendo um entre um íon carbonato, um íon bicarbonato e gás dióxido de carbono para gerar ácido succínico. O ácido succínico é obtido coletando-se o ácido succínico produzido.
