PROCESS FOR THE PRODUCTION OF BACTERIAL NANOCELLULOSE FROM LIGNOCELLULOSIC BIOMASS OF EUCALYPTUS GLOBULUS AND CULTURE MEDIA AND NANOCELLULOSE PRODUCED ACCORDING TO THE PROCESS

摘要

The present invention relates to a process for producing bacterial nanocellulose using sugar-rich liquor from Eucalyptus globulus lignocellulosic biomass. The process consists on cooking lignocellulosic biomass from Eucalyptus globulus, hydrolyzing the resulting pulp, constituting a culture media which includes the resulting sugar-rich liquor, inoculating the culture media, fermenting the culture media and washing the nanocellulose bacterial obtained. The described process and associated culture media allow the production of bacterial cellulose in yields comparable or even higher than with other common culture media, without requiring any detoxification step and without potentiating any inhibitory effect on the production of nanocellulose. Additionally, it allows for a greater sustainability of the pulp and paper industry and of the production of bacterial cellulose, by enabling the use of residual biomass.
