Abstract
"PROCESSO CONTìNUO DE FERMENTAçãO PARA A PRODUçãO DE MANTA CELULóSICA BACTERIANA". A presente invenção refere-se a um processo contínuo de obtenção, em escala industrial, de mantas de celulose bacteriana de alta pureza e propriedades físico-químicas específicas, utilizada para diversos fins. Mais especificamente, a invenção refere-se a um processo para obtenção de múltiplas mantas de celulose bacteriana sem a necessidade de repor na bandeja um novo meio de fermentação, dito processo compreendendo as etapas de: a) preparo do meio de fermentação: dissolução dos componentes do meio em água; b) esterilização do meio: aquecimento do meio a 115<198>C, mantendo-o a essa temperatura por 20 minutos; c) resfriamento do meio até sua temperatura chegar a 30<198>C; d) inoculação do meio com uma suspensão de bactérias; e) distribuição do meio nas bandejas; f) manutenção das bandejas em repouso durante a fermentação; g) retirada das mantas, 'ordenhando-as' sobre as respectivas bandejas; h) repetir o ciclo de manutenção das bandejas em repouso durante a fermentação e de retirada das mantas das bandejas, 'ordenhando-as' sobre as respectivas bandejas até que, após a retirada e ordenha da manta, o volume de meio na bandeja seja de 15% a 25% do volume inicial; i) adicionar a cada bandeja, ao se alcançar o volume de 15% a 25% do volume inicial, novo meio de fermentação, de modo a recompor o volume inicial; j) repetir o ciclo de manutenção das bandejas em repouso durante a fermentação e de retirada das mantas das bandejas, 'ordenhando-as' sobre as respectivas bandejas até que, após a retirada e ordenha da manta, o volume de meio na bandeja seja de 15% a 25% do volume inicial, quando se adiciona novo meio de fermentação e se reinicia o ciclo.
