| titleOfInvention | Continuous fermentation process to produce bacterial cellulosic sheets |
| abstract | The present invention refers to a continuous industrial production process to obtain bacterial cellulosic sheets with high purity and specific chemical and physical properties, which can be used for various purposes. More specifically, the invention refers to a process to obtain multiple bacterial cellulose sheets without the need to replace new fermentation medium in the tray, said process comprising the following steps: a) preparation of the fermentation medium; dissolution of medium components in water; b) sterilization of the medium: heating of medium to 115°C, keeping it at that temperature for 20 minutes; c) cooling of the medium until its temperature reaches 30 °C; d) medium inoculation with a suspension of bacteriae; e) distribution of the medium in the trays; f) the trays are left to rest during fermentation; g) harvest of the sheets, draining them over the corresponding trays; h) repetition of the fermentation in the trays left to rest during fermentation and harvest of the sheets from the trays, draining them over the corresponding trays until, after taking and draining the sheet, the volume of medium in the tray is between 15% and 25% of the initial volume; i) when the volume of 15% to 25% of the initial volume is reached, a new fermentation medium should be added to the tray in order to reach the initial volume again; j) repetition of the fermentation in the trays left to rest during fermentation and harvest of the sheets from the trays, draining them over the corresponding trays until, after taking and draining the sheet, the volume of medium in the tray is between 15% and 25% of the initial volume; when new fermentation medium is added and the cycle is re-started. |
