Abstract

Patente de Invenção: <B>"BACTéRIAS DO áCIDO LáCTICO GENETICAMENTE MODIFICADAS TENDO ATIVIDADES MODIFICADAS DE REDUTASE DIACETILA"<D>. bactérias do ácido láctico geneticamente modificadas tendo uma atividade de redutase diacetila, atividade de redutase de acetoína e/ou atividade de desidrogenase de butanodiol reduzida ou eliminada ou intensificada são proporcionadas. Tais bactérias podem ser usadas em culturas de iniciação na produção de produtos alimentícios, incluindo produtos lácteos onde é desejado ter um elevado teor diacetila e para a redução ou remoção completa da diacetila em bebidas, incluindo cerveja, sucos de fruta e determinados tipos de vinho, onde a presença da diacetila é indesejada.
