One embodiment of the present invention is an improved sheet glass forming apparatus. for between 1 and 10 minutes in a reactor, collecting the pre-treated material in a cyclone and separating the liquid and solid fractions by filtration in a filter press, introducing the solid fraction in a fermentation deposit, adding a cellulase at a concentration of 15 UFP per gram of cellulose and 12. The outlet element is held substantially immovably in position on a fixed portion of the body surmounting the reservoir, the actuating element being independently mounted relative to the fixed portion of the body. The indicating data and movement data are received in the computer system and the text field is identified from the indicating data. In a preferred embodiment, the process involves providing \u201cclean\u201d precursors as starting materials in the catalyst preparation.
