Abstract: An apparatus for securing a wrap or sheet roll is disclosed. The apparatus includes a cable in which a first end of the cable is mounted to a structure and a second end of the cable is mounted to a base plate. The apparatus further includes a lock notch provided at the cable. The apparatus has a lock pin removably mounted to the lock notch. The apparatus also has a lock plate mounted to the cable. The apparatus includes a sheet roll mounted to the cable as well. The sheet roll is mounted to the cable by drawing the base plate through an opening provided at the sheet roll. The lock plate is placed above the sheet roll and the lock pin is mounted to the lock notch to secure position of the sheet roll between the lock plate and the base plate.

Abstract: Cells are cultivated in a chamber having a high nutrient humidity. Gas drives liquid nutrient through devices which produce a fine mist within the chamber. Screens or convoluted mesh supports the cells, and provides for drainage of cell products and media away from the cells for processing. The chamber is sealable to provide for axenic conditions.
