Abstract

"PROCESSO PARA RECUPERAçãO DE POLIHIDROXIALCANOATOS (PHAs) DE BIOMASSA CELULAR". A partir de uma biomassa bacteriana obtida por fermentação e na forma de um lodo de biomassa celular em suspensão aquosa, compreendendo as etapas de: submeter o lodo a operações de injeção de solvente de PHA, de agitação e de aquecimento, para formar uma suspensão compreendendo solvente de PHA com o PHA dissolvido, água e resíduos insolúveis; recuperar o solvente enriquecido com o PHA; resfriar rapidamente a solução de solvente de PHA, para precipitar o PHA dissolvido; micro-filtrar a suspensão de PHA precipitado no solvente, para separar uma pasta concentrada de PHA precipitado; lavar com água, aquecer e agitar a pasta de PHA concentrada, para prover a evaporação do solvente e a obtenção de uma suspensão contendo grânulos de PHA; agitar e cisalhar os grânulos de PHA e esgotar o solvente residual; e separar as partículas de PHA purificadas da suspensão.
